Sex pheromone of Acrolepiopsis nagaimo Yasuda (Lepidoptera : Acrolepiidae), a predominant leafminer on Chinese yam in Tottori Prefecture: identification and field attraction
Applied Entomology and Zoology 36 (1), 71-76
Abstract: Three EAG-active components were detected in the GC-EAD analyses of the hexane extracts of abdominal tips from virgin females of Acrolepiopsis nagaimo Yasuda (Lepidoptera: Acrolepiidae). These components were identified as (Z)-11-hexadecenyl acetate (Z11-16:Ac), (Z)-11-hexadecenal (Z11-16:Ald) and (Z)-11-hexadecen-1-ol (Z11-16:OH) at 1.8, 0.6, and 0.2 ng/female, respectively, by subsequent GC-MS analyses and chemical derivatization. In a field test conducted at Daiei-cho, Tottori in 1998, more males were captured with blends of Z11-16:Ac and Z11-16 Ald (0.1 mg/septum) at ratios of 50: 50 and 75: 25 than with two 2- to 3-d-old virgin females while the effect of an addition of Z11-16:OH to the blends was unclear.
