Sex pheromone components of the blueberry leaftier mothCroesia curvalana kearfott (Lepidoptera: Tortricidae).

The GC-MS and GC-EAD analyses of sex-gland components and sex-gland-released volatiles have identified (E)- and (Z)-11-tetradecenal (90∶10) and (E)- and (Z)-11-tetradecenyl acetate (85∶15) as components of the sex pheromone chemical communication system ofCroesia curvalana (Kearfott). The aldehyde-to-acetate ratio of 9∶1 was found in the gland-released components. This blend at a 0.1-1 μg/day release rate from PVC lures was shown to be as effective as virgin females in the trapping of maleC. curvalana.
