Pesticide Resistance in Stored-Product Insects and Alternative Biorational Management: A Brief Review

Abstract

Conventional pesticides are being used as the major tools for stored grain and food  protection. Many conventional pesticides  have created problems including pesticide resistance, toxic residues in the treated products,  handling hazards, health hazards to operatives and pest resurgence. Among these, the incidence of  pesticide resistance is a growing problem in stored product protection. Problems associated with  synthetic pesticides, especially pesticide resistance, have created a worldwide interest in the  development of alternative biorational strategies. Plant-derived materials, biological control  agents, insect growth regulators, solar disinfestation systems, use of inert dusts and diatomaceous  earth, etc., are potential viable alternatives. Most of these alternatives have low toxicity or are not toxic to humans, making them environmentally acceptable and enabling them to be incorporated in  stored product protection.
