“…Overall, we observed some sort of increase in mortality of cowpea bruchid eggs and decrease in adult emergence with an increase in exposure time of solar heat treatment as indicated by the correlation and regression analyses. This is in consonance with earlier reports by Lale and Ajayi (2001) and Lale and Vidal (2003) who studied the effect of solarization on egg mortality and progeny emergence of C. maculatus and showed that; solar heat treatment of cowpea seeds can adequately control infestation by cowpea seed bruchids. It has been shown that exposing infested cowpea grains to a temperature of 57 0 C for 1 h in an oven kills all the immature stages (eggs, larvae and pupae) of C. maculatus within the seeds -this temperature per exposure time was thus reported as the thermal death point of C. maculatus (Murdock and Shade 1991).…”

“…Post-harvest losses of up to 90% due to heavy infestation by C. maculatus on stored cowpea have been reported (Radha and Susheela 2014). The infested cowpea seeds become less desirable for human consumption and most times are not used for seeds and market purposes as a result of insect eggs and exit holes appearance on seeds (Lale and Ajayi 2001).…”

Post-harvest losses caused by Callosobruchus maculatus is a major constraint to cowpea production and the improper use of synthetic insecticides by most farmers have resulted in environmental, health hazards, and development of insecticide resistance in insects. This study evaluates the efficacy of solar heat treatment using double-layered black polypropylene sheets in suppressing the development of the cowpea bruchid eggs and the effect of the heat absorbed on the germination potential of cowpea seeds. Five pairs of 2 – 3-day old adult C. maculatus were allowed to oviposit for ten days on 50 g cowpea seeds in a glass jar in the laboratory before exposure to 24, 48, 72 and 96 h solar heat treatment regimes. Infested cowpea seeds but not exposed to solarization was set along with the treatments while uninfested cowpea seeds was also set along and used as part of the germinability test. The experiment was laid out in a completely randomized design and treatments were replicated four times. The results showed that there were no significant differences among the number of eggs laid by adult C. maculatus on the cowpea seeds before solar heat treatment. Solar heat treatment of the cowpea seed at 24 h achieved 100% egg mortality of C. maculatus thus preventing adult emergence. The effect of solarization on seed viability showed that there were no significant differences between the infested cowpea seeds exposed to different solar radiation regimes when compared to uninfested cowpea seeds – range; 74% – 99% germination. The results showed that 24 h solar heat exposure of cowpea seeds in double-layered black polypropylene sheets could be the thermal death point of C. maculatus eggs on the seeds in the study area.

“…These results were similar to the findings of Mekasha (2004) who reported that exposure to solar heat for 75 and 90 minutes significantly affected seed viability of adzuki bean. In contrast, Lale and Ajayi (2001) found that solarization in metal tins for 7 hours with temperatures of up to 57 °C had no significant adverse effect on germinability of bambara groundnut seeds.…”

“…Insects (mainly stored grain pests) have been controlled by soil solarization to some extent as well. Soil solarization was observed to change soil chemistry which may weaken or kill some kinds of soil organisms ( McFarlane, 1989 ; Elmore et al, 1997 ; Lale and Ajayi, 2001 ; Minarro and Dapena, 2003 ; Gill and McSorley, 2010 ; Summers et al, 2010 ).…”

Plant protection represents one of the strategies to fill the yield gap and to achieve food security, a key topic for India development. Analysis of climate risks for crops indicates that South Asia is one of the regions most exposed to the adverse impact on many plants that are relevant to inhabitants exposed to food safety risks. Furthermore, accumulation of pesticide residues in the aquatic and other ecosystems is becoming a significant threat in India. These perspectives require to develop programs of crop protection that can be feasible according to Indian rural development and pollution policy. Here we review the research works done on soil solarization in India. Soil solarization (also called plasticulture) is an eco-friendly soil disinfestations method for managing soil-borne plant pathogens. This is the process of trapping solar energy by moist soil covered with transparent polyethylene films and chemistry, biology and physical properties of soil are involved in pest control. So far, this technique is applied in more than 50 countries, mostly in hot and humid regions. India has 29 states and these states fall under five climatic zones, from humid to arid ones. We report pest management application in different climatic zones and their effects on production, weeds, nematodes, and pathogenic microorganisms. The analysis of soil temperatures and crop protection results indicate as environmental requirement for soil solarization fits in most of Indian rural areas. Soil solarization is compatible with future Indian scenarios and may support Indian national food security programs.
