摘要

I tested the hypotheses that gum-frass semiochemicals induce oviposition by mated female peachtree borers, Synanthedon exitiosa (Say) and attract S. exitiosa larvae. In coupled gas chromatographic-electroantennographic detection (GC-EAD) analyses of Porapak Q-collected gum-frass volatiles, 21 compounds elicited responses from male or female antennae. These compounds included four acids, four hydrocarbons, four ketones, three acetates, two aldehydes, gamma-decalactone, conophthorin, 2-phenylethanol, and 2-isopropyl-3-methoxypyrazine. All groups of compounds, except the acetates, were needed to induce oviposition by females. Two of these components, (9Z,12Z)-octadecadienyl acetate and (9Z)-octadecenyl acetate, are larvae-produced. When they were tested as candidate pheromone components, they attracted larvae in Y-tube olfactometers. My data suggests that gum-frass semiochemicals play a significant role in oviposition decisions by female S. exitiosa, and that larvae produce a pheromone of as yet unknown biological significance.; Keywords.
