Sex pheromone components of the redbanded leafroller,Argyrotaenia velutinana (Lepidoptera: Tortricidae)

Abstract

Secondary pheromone components of the redbanded leafroller from female moth extracts have been identified as dodecyl acetate andtrans-11-tetradecenyl acetate (t11–14∶Ac). The ratio of t11–14∶Ac to the primary pheromone componentcis-11-tetradecenyl acetate wasca. 9∶91 in abdominal tip extracts and 12∶88 in female effluent collections, whereas the optimal ratio for attraction in field test was 6∶94 in the spring flight and 6–10∶94-90 in the summer flight. Dodecyl acetate was collected from calling females in ratios to the 14-carbon acetates as high as 5∶:4; in field tests these chemicals were the most attractive in ratios of 3∶2 and 2∶1.
