Solar Disinfestation

The use of solar heating in excess of 50 degrees centigrade to disinfest stored commodities was reviewed by Hansen et al. 2011. Additional references not included in their review are given here. Early papers include Thompson 1915, Rahman 1942 and Reppert and Bentley 1936. An additional 5 papers were published between 1968 and 1977. The majority of the work (61 papers) have been done more recently.

Aspects of solar disinfestation have been investigated for 16 insect species infesting stored products (Acanthoscelides obtectus, calliphorids, Callosobruchus chinensis, Callosobruchus maculatus, Callosobruchus subinnotatus, Caryedon serratus, codling moth, dermestids, nitidulids, Prostephanus truncatus, Rhyzopertha dominica, Sitophilus oryzae, Sitophilus zeamais, Tribolium castaneum, Trogoderma granarium and Zabrotes subfasciatus) and 20 commodities. The commodities included cereal grains (maize, sorghum and wheat), grain legumes (azuki bean, black gram, chickpea, cowpea, gram, lentil, mung, pea, Phaseolus beans and pigeonpea) and others (bambara groundnuts, catfish, cocoa beans, figs, museum artifacts, peanuts and tamariad pods).

Solar heating of commodities was done in plastic bags, metal tins, cardboard boxes and clay pots, by spreading commodity on various surfaces and in solar ovens of various designs. Studies measured the commodity temperatures reached after various exposure times to solar heating and the effect of commodity depths. Effects solar heating on seed germination and cooking qualities were also considered.
