Modern groups of insecticides: diamides and meta-diamides

Abstract

The review summarizes and analyzes the data of foreign authors on the practical efficacy, mechanisms of action and insect resistance concerning insecticides of the groups of diamides and meta-diamides. The prospects of their application in Russia in agriculture and medical disinsection are considered. Insects resistant to OР’s, carbamates, pyrethroids remain the susceptibility to diamides and meta-diamides. Broflanilide, a pro-insecticide, which, due to its transformation into desmethylbroflanilide in the body of arthropods, acquires physicochemical properties leading to improved lipophilicity, water solubility, stability, affecting systemic activity, slowing down the action on harmful insects and increased selectivity for non-target species, is considered in detail. In several countries of the world where diamides are widely used in the controlling agricultural pests, a high resistance of several species of noctuids, diamondback moth, pyralid moths, tomato leafminer, etc. has been established. The key factors that determined the resistance to diamide in Thailand were the lack of insecticide rotation, minimal crop rotation, insufficient insecticide dosage, and irrigation. The necessity of introducing diamides and meta-diamides into the insecticide rotation schemes in order to control the insects resistant to traditionally used active substances was revealed.
