The impact of microwave radiation and cold storage on Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) under laboratory conditions
Abstract :The feasibility of using different types of microwave radiation and cold storage to control the Callosobruchus maculatus (F) in stored grains was evaluated. The mortality rate of adult insects at 200 W power level, different exposure times (0, 2, 4, 6 and 8 min) and 48 h cold storage period was determined. Moreover, different age groups of C. maculatus´s eggs were exposed to 100 W power level and 0, 2, 4, 6 and 8 min exposure periods at 48 h cold storage period. There was a direct relationship between mortality rate and exposure times. Furthermore, the results imply a significant difference in susceptibility of adult insects in using radiation priori or post cold storage treatment. Likewise, a direct positive relationship between mortality rates and microwave radiation exposure times was observed. At the power level of 100 W and 48 h cold storage period, 3-4 days-old eggs were more tolerant than the other age groups, followed by 4-5, 1-2, 2-3 and 0-1 days-old eggs
