Insecticides on the basis of analogs of insect juvenile hormones

Abstract

Analogs of juvenile hormones (JHAs)—azadirachtin (NeemAzal, EC (10 g/L), fenoxycarb (Phasis, WP (250 g/kg), and pyriproxyfen (Admiral, EC (100 g/L) and Inoxyfen, EC (100 g/L)—have been tested. The effectiveness of insectoacaricide NeemAzal in regulating the population numbers of sucking insects was assessed using glasshouse cucumber in Leningrad oblast. Three applications of this product in 0.5% concentration effectively protected this culture against red spider mite (Tetranychus urticae Koch.) and onion thrips (Thrips tabaci Lind) and, less significantly, against melon aphid (Aphis gossypii Glov). Insecticide Phasis protected vineyards against European vine moth (Lobesia botrana Den&Schiff). Juvenoid Admiral effectively decreased the number of imagoes and larvae of greenhouse whitefly (Trialeurodes vaporariorum Wsfw.) in glasshouse cucumber and tomato in different regions of Russia, while Inoxyfen protected apples against codling moth (Cydia pomonella). The tested products belong to the group of biorational pesticides that can be used in ecologically sound systems of plant protection.
