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 maleCryptoblabes 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 ofZ11–16∶Ald andZ13–18∶Ald on each GLC column. These fractions contained insufficient material for further chemical work. SyntheticZ11–16∶Ald andZ13–18∶Ald had the greatest EAG activity of a series of monounsaturated 12−, 14−, 16−, and 18-carbon alcohols, acetates, and aldehydes. Various ratios ofZ11–16∶Ald andZ13–18∶Ald were tested in traps, and a 1∶1 mixture was the most attractive. Addition of small amounts of the correspondingE isomers significantly increased trap catches.
