Laboratory test on the control efficacy of green insecticides against Spodoptera frugiperda.

Abstract

In order to retard the increase of resistance of Spodoptera frugiperda to chemical pesticides, reduce the use of traditional chemical pesticides, and improve the control effect of S. frugiperda, the indoor toxic effects of 15 kinds of green insecticides, including biological, mineral and insect hormones to the S. frugiperda eggs and second instar larvaes were studied. The results showed that chlorbenzuron, guanidine urea, short-lived bacillus and Bacillus thuringiensis were the preferred pesticides to replace traditional chemical pesticides against S. frugiperda, especially low-toxic and easily degradable insect hormone pesticide chlorbenzuron and living microorganism short-lived bacillus had the best effects, which had good application value in practical production. The botanical pesticides veratrine, rotenone, azadirachtin, matrine, pyrethrin, teasaponin and mineral pesticide mineral oil had poor control effects on S. frugiperda, which were not recommended touse alone in large-scale.
