Lactones 10. Hydroxy and acetoxy terpenoid lactones - synthetic insect feeding deterrents
Committee on Biotechnology PAS ; Institute of Bioorganic Chemistry PAS
Several terpenoid 8-hydroxy-y-lactones, y-hydroxy-5-lactones and their acetates were tested for feeding deterrent activity on three storage pest insects,the granary weevil beetle (Sitophihis granarius L.), the confused flour beetle (Tnboliiim confusiim Duv.) and the khapra beetle (Trogoderma granarium Ev.). Homoterpenoid trans 5-hydroxy-y-lactone 12 showed high, comparable with azadirachtin, activity against the adults of Tribolium confusiim. Its cis isomer (17) wasalso very strong antifeedant but towards the larvae of Trogoderma granarium.The results indicate that the feeding deterrent activity depends on the shape ofthe molecule of the tested compounds. The effect of the configuration of chiralcentres present in the molecule as well as geometry of substituents at the lactone ring on the deterrency was observed. The antifeedant activity also dependson the developmental stage of the insects.
