The following list of references includes many from Myers and Hagstrum 2013 and additional references, websites and annotations are included to expand upon their summary. Several studies predict possible establishment of the khapra beetle, Trogoderma granarium, based upon climate (Banks 1977 for Australia, Sinha 1963 for Canada, Bahr 1966 for East Germany, Dal Monte 1960 for Italy, Mitsui 1965 and Sinha and Utida 1967 for Japan, Howe and Lindgren 1957 and Howe 1958 for U.S.A.). The suitability of climate in Iran (Freeman 1958a), Nigeria (Howe 1952), Pakistan (Freeman 1958b) and Turkey (Freeman 1962) for Trogoderma granarium has also been considered. Some of the references are to research supporting regulatory effort or to educational materials prepared to help involve public in regulatory programs. Additional relevant references can be found on Life History and Population Ecology pages.
Khapra beetle destroys more commodity than it consumes. Khapra in Hindi and Urdu means “the destroyer”. Khapra beetles have wings but cannot fly. Larval diapause allows it to survive for several years without food. Diapausing larvae tend to remain hidden, but may come out of hiding to feed. It feeds on many commodities and is more tolerant than other species to many pesticides and extreme temperature and relative humidity, preferring high temperatures and low relative humidities for larval development. In Australia, Trogoderma variabile was not eradicated as easily as Trogoderma granarium because it was able to disperse by flight (Butcher 1994, Castalanelli et al. 2011, Emery 1999) and a strategy of containment was adopted.
Several dichotomous keys using adult and larval morphology for species identification are available (Anonymous 1955, 2016, Banks 1994, Barak 1995, Beal 1956, 1960; Kingsolver 1963, Mawlood and Abdul-Rassoul 2000, Okumura 1955, 1966, Okumura and Blanc 1955, Zhongping et al. 2017, Zhang et al. 2008) and there have been several studies developing molecular identification methods (Chen et al. 2010, Khidr et al. 2017, Ma et al. 2009, Olson et al. 2014, Shen 1994, Stuart et al. 1994, Yulin et al. 1999, Zhang et al. 2017, Zheng et al. 2016). There are generally more larvae than adults to be identified because larvae diapause and may be in the larval stage for several years while adults are short lived. Burges (1959b) found that insects in larval stage for more than 7 weeks are in diapause. Trogoderma granarium is a species with data in Barcode of Life Database (BOLD) software in the GenBank but this data has not been open to the public (Boykin et al. 2012). Further field validation of the reliability of the molecular identification methods identifying species are likely to be needed before these methods are used.
Six lists of locations (1977 to 2016) at which khapra beetle is reported as currently or previously present or intercepted in imported commodities are compared in Locations with Khapra table. Myers2012 list includes only records for imports into the US and 43 locations. Australia2016 includes 75 locations. The second column of table shows the number of lists in which a location is included. Twenty six percent of 129 locations are on 4 or 5 of lists and 40 % are on only 1 or 2 lists. Yugoslavia may include Croatia, Serbia and Slovakia, and United Kingdom may include England and Ireland. EPPO2016 and Banks1977 list include 75 and 59 locations and categorize all locations while French2005 list includes 90 locations, but does not categorize all (location name is given when not categorized). SPIR2009 list includes 89 locations. The Central or South American countries, Argentina, Bolivia, El Salvador and Uruguay are only on 1 or 2 lists, but Venezuela is on 4 lists. Banks1977 and French2005 provide literature citations for the sources of records.
Before containerized shipping was introduced in the late 1960’s, cross infestation between cargos in a ship’s hold and infestation of commodities from residual insect infestations in ship’s hold were a problem (Hurlock 1962). Shipping containers should reduce the cross infestation problem, but carryover of residual infestations in shipping containers is now a problem. Many of khapra beetle interceptions are probably a result of shipping containers used for agricultural products later being used for non-agricultural products such as screws, rain ponchos, wood veener and automobiles. When khapra beetle infested residues remain undetected in empty shipping containers, a khapra beetle infested shipment may originate anywhere in the world that these shipping containers are used.
The following table sorts locations by their relative importance as sources of khapra beetle infestation in international trade based upon comments from CABI and EPPO. The table also provides a chronology of some of the expansion of khapra beetle geographic distribution. Locations with Khapra table above has an additional 50 locations not in this table. No. Lists column refers to the number of lists in Locations with Khapra table above that included a location.

Available from: URL: http:// http://www.aphis.usda.gov/import_export/plants/manuals/online_manuals.shtml. * Indicates from another source.
The host range for the khapra beetle, Trogoderma granarium, has been studied in two ways: by recording the commodities infested and by determining in the laboratory whether commodities are suitable for their development. Khapra infested_suitable commodities table shows that 31 commodities have been studied using both methods. Multiple infestation records (2-6) are available for many commodities and more records are available for grains (maize 7, rice 12, wheat 12) and peanuts (11). The majority of these commodities (20) were suitable for development in 1-3 studies or for wheat in 6 studies. In a few cases (4) commodities were suitable in one study but not another. The remaining 7 commodities although found to be infested were not suitable for development in laboratory studies. Another 110 commodities have been studied by one of the two methods. Twenty six of these commodities were found to be suitable for development in the laboratory. The final 44 commodities in the list have been shown to be unsuitable for development in the laboratory.
The Atlas and SPIR together had 104 host commodities and the other five publications, each with 27-38 hosts, added 38 new hosts that were not in the Atlas or SPIR (Host of khapra table). Overall, the 143 hosts were in 22 of the 28 commodity categories in the Atlas (p. 201). Fifteen of the hosts were in 4 to 6 of the publications and these hosts included some of the most prevalent commodities in the marketing system. The majority of these were grains (6) or pulses (6). A little more than half (74) of the host commodities were only in one of the six publications. About one third (27) of these were seed and 22 were from 1955 to 2005 publications. CERIS2004 called several of hosts grocery items (groc) and indicated that khapra beetle could not fully develop on 4 hosts. Strong1959 classified host commodities as primary (prim), secondary (sec) or miscellaneous (misc).
The following table has information from 62 press releases for khapra beetle interceptions between 2010 and 2018 (United States Customs and Border Protection web site, https://search.usa.gov/search?query=Trogoderma&op=Search&affiliate=cbpgov ) and 12 additional interceptions in 2012 (Mason 2013). The number of interceptions included was highest with 16 in 2011 and 19 in 2012, and ranged from 2-11 for the other years. More interceptions were on rice (32) and bean (9) than any other commodity. Khapra beetle was intercepted 1-3 times on each of an additional 21 commodities, many of them legumes. Rice was the only cereal grain. Nearly half of the interceptions were in airline passenger luggage. Interceptions on screws, rain ponchos and wood veener were probably a result of the carryover of khapra beetle infestations in shipping container from previous cargo. The most interceptions were for commodities from India (19) Saudi Arabia (18), Sudan (11) and Pakistan (7). There were 1-6 interceptions from 9 additional countries.

A preliminary survey of 492 warehouses, milling and grain-handling establishments in 10 states – AZ, CA, CO, ID, NV, NM, OR, TX, UT, WA – from early April until mid-June found khapra beetles in 25 warehouses (Padget 1954). The beetle had been shipped from Arizona to New Mexico in sorghum seed. Additional survey of 4,500 properties in AZ, CA, CO, LA, NM, OK, TX and other states, found khapra beetles in 63 in AZ, 158 in CA (of which at least 45 made interstate shipments) and 4 in NM.
Shipping records of the past two years were examined for shipments likely to carry infestation. Inspections were made at destinations and railway cars carrying bulk grain. Four hundred cars were inspected. One dealer whose warehouse was infested with khapra beetle shipped to 30 states in the US and 3 in Mexico.)

(Khapra beetle was found in >200 establishments in Arizona, >300 in California, 19 in New Mexico, 22 in Texas and 84 in Mexico. For eradication, buildings were wrapped with gas tight tarpaulins and fumigated with 5 lbs of methyl bromide per 1,000 cu ft for 48 hours. The area surrounding the structures was treated three times at 3-7 day intervals with a spray containing 5 lbs of malathion in each 100 gallons of diesel fuel. The sprayed area was raked or harrowed between applications to assure wetting of all debris and other materials.
When infested premises were treated in this manner, they can be released from regulation immediately. If infestations are light, other approved procedure may be used. Only part of the structures on infested premise may be treated or structures may be treated without draping with tarpaulins. If the modified procedure is used, the infested premise must remain under regulation for a year. Three inspections at least 90 days apart with the final during the last month of period must show that the premises are free of infestation before they can be released.)
Anonymous 1978. Khapra beetle (Trogoderma granarium). USDA. Cooperative Plant Pest Report 3(10): 76. The first active infestation by Trogoderma granarium (Everts) in the eastern USA was detected in a warehouse at Linden in New Jersey in February 1978, where 2 larvae and some cast skins were collected from wood-borer holes in imported wooden crates containing wooden screens; additional larvae, cast skins and 1 dead adult were subsequently found at large in the same warehouse. Fumigation of the warehouse and delimiting surveys are planned. The last active infestion by T. granarium in the USA occurred in the west of the country in 1966.

Presented at the 10th Annual Conference, North Central Branch, Entomological Society of America, East Lansing, Michigan, March 24-25, 1955. (At the invitation of the Directors of the Western State Experiment Stations, the Stored-Product Insect Section of the Agricultural Marketing Service established a field station at Mesa, Arizona in August 1954 to conduct research on the khapra beetle under the direction of G. H. Spitler.
The Western States Cooperative Regional Project WM-16 was already set up for Maintaining Grain Marketability by Insect Control in Storage so this project was broadened to include a study of the khapra beetle, and a subcommittee headed by A. E. Michelbacher of California was established to coordinate research on this insect by the USDA, Arizona and California.)
Cotton, R. T. 1960. Let’s kill the Khapra beetle invader. Northwestern Miller, 264(8), 42-44. (Perez Simmons in February 1939 received a khapra beetle from wheat in Madera County California. Larvae seek hiding places for aestivation in many nonfood commodities so they can be found in an endless variety of products. If allowed to spread, khapra beetle could be a major pest of seed establishments, feed mills, malting houses, flour mills, powdered milk factories, cereal plants, grain elevators, nut storage and packing plants, warehouses handling dried food products and in farm grain storage.
During 1954 and January 1955, quarantine measures were adopted by the states of AZ, CA, CO, GA, KS, LA, NV, NM, OK, OR, TX, UT and WY. By October 1960, the number of properties found and fumigated since the beginning of the program in 1955 are: Arizona 242, California 341, New Mexico 19, Texas 28 and Republic of Mexico 87 representing 170, 945, 254 cu ft. All of the formerly infested properties except three in Texas have been released from quarantine.
During the period of July 1, 1959 to June 30, 1960 the pest was intercepted 133 times on 82 ships with approximately 58, 900 inspections by Plant Quarantine Division. Subsequently, khapra beetle was found in imported peanuts in New York and through June 24, 1960, 55 cargoes have been found to be infested involving 45 different ships.
Khapra beetle ntercepted at ports of entry on gum karaya, gum Arabic, seed lac, baled bagging, crude guar meals and hulls, cotton card strips, tumeric roots, baled crepe rubber, automobiles, steel wire, steel beams, kegs of bolts, metal drums, soiled linen, oil paintings, rice, myrobalan, nuts, peanuts, cumin, poppy seeds, guar embryos and dried animal skins.)

Further inspections in 1954-59 showed that the beetle was present in cargoes from various countries of the Middle East, and local infestations were found to have become established at Trapani (Sicily), Gravina and Castellammare di Stabia. Control and preventive measures were intensified, and the beetle is thought not to be permanently established anywhere in the country, although the climate in many areas seems suitable. A related species imported in wheat from North America was identified as T. inclusum Lec.)

In early 2013 live khapra beetle larvae were found by Customs and Border Protection at Pembina, North Dakota in a seemingly low-risk shipment of clothes moving from Alberta to Texas. In 2014, larvae and cast skins were detected in dried pigeon peas in passenger luggage arriving from Sudan; in a traveller’s rice package from Saudi Arabia; and stopped in Abu Dhabi, United Arab Emirates in dried chick peas destined for the U.S. In five cases in Dallas, passengers had not declared packages of rice, dried beans, coriander seeds and fava beans from Sudan and India that carried cast skins and live larvae. At the Lewiston Bridge on the Canada and U.S. border, three live larvae were detected in a sea container being hauled into the U.S carrying a shipment of rain ponchos from China. Organic soybeans from India were intercepted in November 2014, and split lentils and spices from United Arab Emirates were intercepted in January 2015. Other live intercepts in 2015 include, declared rice from Saudi Arabia via London; a 2 kg bag of dried beans originating from Somalia; undeclared dried chick peas and peanuts originating from India; and a 13.7 tonne shipment of chickpeas, lentils and other Indian foodstuffs refused entry and re-exported. Cast skins were also detected on dried hibiscus leaves that were packaged with other plastic bags of rice and spices from Iraq. In early 2016, a 25 tonne shipment of cumin seed from India infested with dead larvae was sealed and re-exported.

Risk of introduction of khapra beetle is at a minimum, since foreign barleys are not used; hence there is every opportunity for the eradication of these pests from maltings without fear of re-introduction.

(Today Trogoderma granarium is regularly introduced on oilcakes from Burma, India, Sudan and Nigeria, but was probably introduced to maltings between 1908 (Walker 1917) and 1918 (Mason 1921) in barley from Indian subcontinent. It must have been introduced earlier many times but fail to establish. Douglas (1860) reported khapra beetle in London in rice from Burma. In modern maltings, khapra beetle infestations are prevented by storage of malt under cool conditions.)
Freeman, J. A. 1974. A review of changes in the pattern of infestation in international trade. EPPO Bull. 4: 251-273. Trogoderma granarium may be able to establish in heated buildings such as maltings in temperate climates. Khapra beetle was intercepted 46-131 times per year (6-18 times per 1000 cargos inspected) between 1967 and 1973 in rice, rice bran, groundnuts, cotton seed or groundnut seed cake and gum imported into Great Britian from India, Myanmar, Nigeria and Sudan. In 1969, there was an increase in interceptions on groundnut cake from Nigeria but by 1973 incidence was at a low level again. Rice from Burma is more likely than rice carried in dry cargo containers from Australia and US to be infested by khapra beetle which has not yet (1974) been found in rice from Thailand and China. Trogoderma granarium may be found in rice bran from Myanmar and India and this rice bran is a frequent source of cross infestation of other commodities during international transport. Review of rice bran infestations from Myanmar has resulted in significant reductions in the proportion of heavily infested cargoes.
A large quantity of goods can be inspected rapidly and economically in ship hold and the cargo treated in port before distribution but this is not possible with shipping containers. Shipping containers have not yet (1974) been used for countries whose exports may be infested by khapra beetle. Transhipment into containers in European ports of infested cargoes from the Far East and their movement by short sea routes to minor ports in Great Britain may avoid inspection. Similarly, the increase use of roll-on, roll-off lorries from as far away as Iran and Afghanistan is a problem. Because of difficulty of inspection of shipping containers on arrival, it would be highly desirable for all cargoes liable to insect infestation to be treated in countries of origin and for spot checks to be made on arrival. There is a risk that insects will be spread by remaining after the removal of the infested load and contaminate future loads.

Lefroy said that khapra beetle has been found in wheat in Sidney, Australia but no khapra beetle were found with a very thorough search of the stacks at White Bay and Enfield nor at other locations. There is reason to believe that khapra beetle would not do as much damage as under the dry summer heat of Northern India if it were introduced into Australia where climate is different.

(In 2011, Khapra beetle larvae were detected twice in USA in rice shipped from Pakistan and in 2014, 43000 pounds of infested rice was returned to Pakistan. In 2013, 3000 metric tons of rice from Pakistan infested with Khapra beetle was rejected at Mexico border and returned. Khapra beetle in rice and stiff competition in world rice market resulted in decline of rice exports from 42 million tons to 37 million and 1000 million dollar loss to rice industry in Pakistan.)
Howe, R. W. 1952. Entomological problems of food storage in northern Nigeria. Bulletin of Entomological Research 43: 111-144. The khapra beetle was first observed in Nigeria in 1948 on stored sorghum (guinea corn) stored as a reserve for feeding school children and civil prisoners in Kano. Infestation was eradicated but in January 1949 infested groundnut storage was discovered and khapra beetle was soon too widespread to eliminate, being found at Kaura Namoda 140 miles west north-west of Kano. Evidence was obtained that it had been present on groundnuts in 1946 and probably in 1944. Adults cannot fly and both adults and larvae can be dispersed by wind and on the clothing of workers. The larvae feed on the groundnuts, powdering more than they consume, and also cause weakening of the sacks which ultimately tear. Before 1940 groundnuts were all moved out of storage by April of each year, but in 1946 some were still in storage in November when the next crop was harvested and with overlapping crops since then some were stored for 18 months. Petty theft of nuts and sale of these nuts with the new crop increased the khapra beetles around at the beginning of storage.

Res. 54 pp. Warmth of kiln and malt stores are essential to the development and population growth of Trogoderma granarium and this species is of greatest importance to the brewing and distilling industry in England. Dead larvae render grain sour and raise the water content of malt, making it unfit for use by brewer. The use of English barley is increasing but some is still imported from California, Poland, Australia, India and Chile. Thirteen out of 27 maltsters refuse khapra beetle infested grain and one grain merchant refused delivery of Indian barley to his customer when he found it infested in the ship. In spite of its know preference for warm temperatures, it was found in large numbers in groundnut cake and Indian wheat cargoes on ships and in the fabric of a warehouse in the port of Aberdeen during March. Brewers, maltsters and distillers have spent large sums in replacing wooden bins with steel bins, making other structural alterations and fumigating to eliminate khapra beetle. Complete demolition of two malt bins and treatment of the walls with a blowlamp were successful in its eradication at a distillery in the Highlands. Wet and dried grain, malt culmings and spent hops by-products sent directly from malting to agricultural merchants and farms are occasionally infested by Trogoderma.

Trogoderma granarium was found infesting wheat in 4 of 7 geographical areas of India and was not found in southern, central and eastern areas. It was found on barley in northern region. The lowest percentage damage in the southern area may be a result of Trogoderma granarium being absent. Humidity was lower in areas where khapra beetle was present.

Padget, L. J. 1954. Status of the Khapra beetle in Western United States Spring 1954. USDA Coop. Econ. Ins. Rpt. 4(28): 557-562. (In 1946, khapra beetle was found at J. B. Hill Warehouse Company, Fresno, California and incorrectly identified by pest control company as black carpet beetle. Fumigation was unsuccessful so by 1949 the 300 tons of grain in warehouse was a total loss and warehouse was no longer used for grain storage. Warehouse was gone over with a blowtorch and residual spray, but used bags were moved to Alpaugh and Angola in Tulare, Co., spreading the infestation, filled with grain and used as bulkheads between piles of loose grain. Two infestations in Portales and Texico, New Mexico can be attributed to shipments of sorghum seed for planting from infested facility in Arizona. Three shipments from same facility to Texas and another to Oklahoma were negative.
In November 20, 1953 Cooperative Economic Insect Report discovery of khapra beetle in California was reported and in December 18 infestation in Phoenix warehouse was reported. R. T. Cotton and K. S. Rohwer were assigned by USDA to assist in survey beginning early April. State Pest Control officials provided valuable assistance in selecting mills to inspect and routes to follow. Nevada, Utah and Oregon supplied personnel for survey in those states. Large wholesale grain-handling establishments were included in survey and also feed-mixing plants because they have a wider assortment of ingredients. For example, Farmer’s Cooperative warehouse had several hundred tons of barley and wheat of local origin. Poultry or Dairy Producers Association had smaller tonnage of grain, but also cotton seed meal from Arizona or California, soybean from Minnesota, corn from Iowa and copra from Philippines.
Feed grains, barley and wheat from Arizona and California generally are not shipped north or east. Negligible amounts are shipped to Nevada, Utah and Colorado. Cottonseed meal and cake for areas west of Rockies is supplied exclusively by Arizona and Colorado. Arizona Certified Sorghum seed is prized throughout western states. Burlap bags are supplied to survey area from Los Angeles, San Francisco and Portland.
All commercial warehoused in Arizona and 150 warehouse in California had been inspected so only a few warehouses in these states were included in the survey. Survey included 67 warehouses in Colorado, 77 in Utah, 29 in Idaho, 21 in New Mexico, 6 in Texas, 10 in Nevada and 36 in Oregon and no khapra beetles were found. No warehouses in Wyoming and Montana were inspected.)

(Malt stored in cold bins is never affected by the khapra beetle, infestations only appearing where the temperature approximates 90o to 110o F. Generally speaking the greatest infestation occurs around the walls adjoining the kiln or kiln shafts. The larvae migrate from one part of the building to another, but so far have not been observed on barley floors. Fumigation of the whole premises is the best remedy, though it is difficult to remove all the malt and leave the premises vacant for two or three weeks.)

Pasek, J. E. 1998. Khapra beetle (Trogoderma granarium Everts): pest-initiated pest risk assessment, USDA APHIS, Raleigh, NC. Khapra beetle infestation was detected in 1997 in a spice processing warehouse in Owings Mills, Maryland. Actions taken to contain and eliminate the infestation included: fumigating all shipments leaving the facility, surface spraying the facility with malathion, vacuuming all surfaces to remove dust and insects, sealing surfaces with several coats of thick latex paint, and decontaminating and replacing spice processing equipment. The methods used likely are not economically feasible for most commodity handlers and were chosen, in part, in this instance because the plant intended to remodel the facility anyway. The facility itself was not fumigated due to citizen opposition.
Six countries (India 34% % > Saudi Arabia 22% > Iran 14% > Pakistan 9% > Kuwait 3% > Sudan 2%) accounted for 84% of interceptions of khapra beetle in US from 1985-1998. During 1971-1984, the order was India 44% > Sudan 24% > Pakistan 15% > Iran 5% > Saudi Arabia = Kuwait < 2%.

In 1965, native storehouses containing mainly beans and grains at Kaura Namoda, Northern Region, Nigeria were heavily infested by Trogoderma granarium. Infestation was eradicated by spraying walls with malathion and fumigating, but a storehouse that had just received a fresh stock of grains was found to be heavily infested by Trogoderma granarium. Continued monitoring will be needed since this has long been a source of infestation from which Trogoderma granarium can spread southward along the trade routes.

Meeting of specialists on stored food products. Commission for Technical Co-operation in Africa South of the Sahara Publication No. 31, 1957, Salisbury. Wind currents tended to carry smaller khapra beetle larvae from the walls of shed, some larvae to heights of 12-15 ft above ground. Trogoderma granarium larval (adult) populations on girders were 1915 (100) on rail side of shed; 2584 (570) on south end; 54 (8) on other ground level girders; 166 (82) 5 ft above ground level girders; 8 (nil) and 124 (311) on top girders. Totals of 3150 larvae and 20 adults were collected per 40 sq ft of brick and concrete wall base; 2836 larvae and 45 adults were collected per 40 sq ft of floor/wall edge; 1217 larvae and 73 adults were collected per 100 sq ft of floor area below edges of ruberoid felt covering concrete; 174-291 larvae and 19 to 53 adults were collected per 40 sq ft of wall. Most of larvae were alive; most of adults dead and fewer were collected from outside surfaces of the warehouse. Ground sample and maize spillage 6 ft from warehouse had nil khapra beetle larvae and adults. These residual populations in warehouse make regular sweeping of floor and cleaning girders important before insecticide application.

Between 1971 and 1984, the frequency in percent of khapra beetle interception in United States were by commodity: Gum (17.4%), Sheepskin (16.0%), Artware (13.2%), Capsicum (10.7%), Cotton piece goods (6.2%), Cucurbit (5.4%), Cumin (5.3%), Carpets (4.4%), Foodstuff (3.6%), Automobile (3.2%), Celery seed (2.2%), Cassia (2.1%), Brassware (2.0%), Hibiscus (1.3%), Peanut (1.1%), Rice (1.1%), Pistachio (1.1%), Screens (0.9%), Coffee (0.8%), Niger (0.7%), Goatskins (0.7%), Container (0.7%) with a total of 757 interceptions. Number of other identified hosts with less than five interceptions was 44, total identified hosts = 801 (60%) and total unidentified hosts was 535 (40%). Between 1971-1984, frequency in percent of khapra beetle interceptions in imports into United States by country was India 44% > Sudan 24% > Pakistan 15% > Iran 5% > Saudi Arabia 2%.
For imports from Pakistan into United States for 1982 through 1984, frequency in percent of interceptions of khapra beetle by commodity were Cumin seed (43.2%), Curcurbit seed (18.9%), Bagging (with cargo) (10.8%), Foodstuffs (10.8%), Rice (bagging) (2.7%), Rosa sp. (2.7%), Chickpea (2.7%), Fennel (bagging) (2.7%), Sheepskins (2.7%), Cargo not identified (2.7%) with a total of 37 interceptions
For imports from India into United States for 1982 through 1984, frequency in percent of interceptions of khapra beetle by commodity were Crating (26.2), Cargo not identified (18%), Celery seed (bagging) (9.0%), Gum (bagging) (8.2%), Gum (8.2%), Foodstuffs (bagging) (5.7%), Brassware (crating) (5.7%), Cumin seed (bagging) (4.1%), Rice (bagging) (2.5%), Niger seed (bagging) (1.6%), Cloth (bagging) (1.6%), Dill seed (1.6%), Coriander (bagging) (1.6%), Coffee (bagging) (0.8%), Lentil (bagging) (0.8%), Carpets (0.8%), Beans (bagging) (0.8%), Psyllium sd. (0.8%), Sheepskins (0.8%), Bagging as cargo (0.8%) with a total 122 interceptions.
For imports from Sudan into United States for 1982 through 1984, frequency in percent of interceptions of khapra beetle by commodity were Cucurbit seed (26.6%), Sheepskins (25.0%), Cargo not identified (17.2%), Hibiscus (bagging) (14.1%), Cassia senna (bagging) (7.8%), Gum (bagging) (6.3%), Pepper (bagging) (3.1%) with a total 64 interceptions.
The frequency in percent of the pathways of khapra beetle entry into United States for 1982 through 1984 were Cargo (56.7%), Baggage (29.9%), Ship’s stores (9.5%), Holds (3.2%), Mail (0.5%), Ship’s quarters (0.2%) with a total of 432 interceptions of khapra beetle.
Most khapra beetle infested commodities were accompanied by burlap (bagging). Port of New York accounts for 65% of all cargo interceptions of khapra beetle and eight ports account for 95% of interceptions. Interceptions associated with crating, usually a single specimen, only involved India during 1984 and 1985. There was a recent upsurge of infested celery seeds. Threat posed by carriers to United States has diminished in recent years with the introduction of sea containers and improved sanitation on arriving vessels. In 1979, 33-50% of annual interceptions of khapra beetle were arriving ships and with sea containers they constitute only 9.5% between 1982 and 1984.
Shapas, T. J.; Burkholder, W. E. 1979. Program for using sex pheromones to detect khapra beetle at U.S. ports. Proceedings of the North Central Branch of the Entomological Society of America 33: 30. The trapping method used in a survey and detection programme against Trogoderma granarium Everts at ports in the USA is described. The traps contain dichlorvos (DDVP) for killing the insects, wheat-germ oil to attract the larvae, and 1 mg of the sex pheromone of the species ((Z)-14-methyl-8-hexadecenal) to attract adult males. The use of such traps should greatly increase sensitivity for detection of the pest.

First khapra beetle infestation in the territory of former USSR was found in 1986 in Turkmenistan in malt at Merken brewing plant. In the next two years, 21 infestations were found (Turkmenistan (8), Uzbekistan (4), Tajikistan (5), Russia (2) and Kazakhstan (2)) and infestations in Turkmenistan were eradicated within 3 years. The first detection of khapra beetle in warehouses in the territory of Russia was in May 1987 and two additional infestations were detected in the Stavropol region with live larvae in the batch of fodder corn imported from the United States to the Kochubeevskiy plant of cereal products and Nezlobnenskiy feed milling plant. Both were eradicated.

In 1964, a nation-wide search of 30 properties in Japan found khapra beetle at four breweries some distance from each other in Tokyo, Osaka, Hyogo Prefecture and Fukuoka Prefecture and in two maltings in Tochigi Prefecture near Tokyo and in Shiga Prefecture near Osaka that supplied these breweries. An eradication program involving fumigation with methyl bromide at infested premises, and filling crevices of warehouses and silos with mortar was undertaken.)

Swaine, G. and Mutter, S. 1961. The khapra beetle. Tanganyika Ministry of Agriculture Bulletin No. 7. Tanzania, Kenya, Uganda and Zanzibar passed legislation requiring compulsory treatment of grains, flours, edible oil seed, pulses and beans from India, Pakistan, Myranmar and Thailand in 1956 when khapra beetle infested spices were imported into Zanzibar from the Far East. Bags from all countries except Kenya and Uganda also required fumigation. Early in 1960, serious outbreaks of khapra beetle were discovered at 8 stores in Dodoma, Tanzania and controlled by fumigating the infested articles and spraying interior of the building with insecticides. Only one store at Dodoma had a second outbreak. Legislation was amended to include additional importing countries and commodities. Inspection services were expanded beyond port and search revealed a number of very small outbreaks at widely scattered points that were controlled.

Stored Prod. Res. 26: 43-51. The first record of Trogoderma granarium in South Africa was at Pietermaritzburg in May 1954 in a consignment of malt imported from England in 1953. The malt was promptly processed into beer and no more Trogoderma were found in the premises. There is no evidence of spread to other areas. The second, in June 1955, was a heavy infestation in a mill at Bon Accord near Pretoria, in a stack of sweepings and tailings collected from various sources over 3 years. These were promptly milled as stock feed and the area previously occupied by the stack was heavily sprayed with insecticide. Although the infestation had ample opportunity to spread throughout the warehouse and mill and to disperse further, there have been no further records in the Pretoria area. Between 1955 and 1968 there were poorly documented reports of light infestations of “khapra beetle” at Heidelberg, Transvaal (1955) Lichtenburg horizontal bulk storage (1956) and Standerton (1961) where no beetles seem to have been collected, and from Potchefstroom (1964) Klerksdorp (1965) and Pietersburg (1968). The insects from Potchefstroom and Klerksdorp were identified as Trogoderma versicolor (Creutzer) (now inclusum Le Conte), and those from Pietersburg deposited in the National Collection of Insects have been identified as Phradunoma sp. (Jonsson, personal communication). Thus there is no evidence that Trogoderma granarium was found over this period. In 1972 a severe infestation of T. granarium was discovered in locally produced wheat at Onseepkans, a small irrigation settlement some 190 km west of Upington on the south bank of the Orange River.

Rough cloths suspended over and in contact with grain surface trap Trogoderma granarium larvae prior to pupation and they can be destroyed.
