Thermal Disinfestation of Stored Grain Insects Using Solar Energy

Abstract

system has been developed to achieve this high temperature/short time technique to control Callosobruchus maculatus , one of the most common pests of many legumes. The solar heating system provides an attractive alternative to conventional electric heating systems or gas-fired heating systems. The present results show that the proposed system is successful in suppressing C. maculatus population within 115 min under temperatures from 55 to 57 o C. This thermal range is capable of controlling most of the stored grain insects. Employing solar heating provides a simple, energy-saving alternative to small and medium-scale applications.
