Department of Plant protection, College of Agriculture. University of Guilan. Rasht. P. O. Box 41635- 1314


Aqueous extract from leaves of Sambcus ebulus L. were tested for antifeedant, growth regulation and ovicidal effects against the red floor beetle Tribolium confusum Duv. under laboratory condition (29?1?C, RH 60?5% and 12L:12D). The results indicated a significant deterrence for feeding, and comparatively significant larval, pupal and adult weight decrease in treated vs. controlled insects. Similarly the ovicidal effect of the extract was significant, thus reducing the number of F1 generation of resulting adults.
