Abstract:
A mixture of (Z)-11-hexadecenal (Z11-16: Ald), (E)-11-hexadecenal (E11-16: Ald), (Z)-13-octadecenal (Z13-18: Ald), and (E)-13-octadecenal (E13-18: Ald) on rubber septa (100:10:100:10 μg, respectively) was superior to virgin females in attracting male Cryptoblabes gnidiella Mill. (Lepidoptera: Pyralidae) to traps. A dichloromethane extract of 200 female ovipositors was separated into fractions by gas-liquid chromatography (GLC) on OV-101 and Hi-Eff 8BP. Two fractions had significant electroantennogram (EAG) activity, and had the retention times of Z11-16:Ald and Z13-18:Ald on each GLC column. These fractions contained insufficient material for further chemical work. Synthetic Z11-16:Ald and Z13-18:Ald had the greatest EAG activity of a series of monounsaturated 12-, 14-, 16-, and 18-carbon alcohols, acetates, and aldehydes. Various ratios of Z11-16:Ald and Z13-18:Ald were tested in traps, and a 1:1 mixture was the most attractive. Addition of small amounts of the corresponding E isomers significantly increased trap catches. © 1981 Springer Science + Business Media B.V.
