Chromenes, chromanones and alkyl substituted phenols as antifeedants to storage pests and aphids
Journal of Plant Protection Research 41 (3), 229-239
Abstract: The aim of the work was to study the feeding deterrent activity of precocenes, their synthetic analogues, and some related compunds to storage pests: Sitophilus granarius L., Tribolium confusum Duv., Trogoderma granarium Ev., and aphids: Myzus persicae (Sulz.). Among all tested compounds precocenes I and Il exhibited the best feeding deterrent activity against all tested insects. 4-Chromanols (16, 17 and 18), alcohols 19, 20 and 3-chromanone (15) showed high deterrence towards the larvae of T. confusum. The best antifeedant activity towards the adults of both T. confusum and S. granarius was observed for substituted phenols with methoxy group at benzene ring. The biological tests carried out on aphids showed that the presence of methoxy group in the molecule was a crucial structural factor for the appearance of antifeedant activity against these insects.
