SEX PHEROMONE OF THE MAPLE LEAF ROLLER CENOPIS ACERIVORANA (LEPIDOPTERA: TORTRICIDAE)

Abstract

AbstractPheromone gland rinses of female maple leaf roller moths were analyzed by capillary gas chromatography and found to contain (Z)-11-tetradecenal, (E)-11-tetradecenal, tetradecanal, (Z)-11-tetradecenyl acetate, (E)-11-tetradecenyl acetate, and tetradecyl acetate in the average ratio of 33:20:8:21:17:2 for single female analysis and 31:16:6:16:27:3 for a pooled extract of 55 females. Identity of the tetradecenals, the tetradecenyl and tetradecyl acetates was confirmed by gas chromatography/mass spectrometry. Electroantennogram analysis indicated that (Z)-11-tetradecenal followed by (E)-11-tetradecenal were the most stimulating compounds tested. In field tests, only three components (Z)-11-tetradecenal, (E)-11-tetradecenal and (Z)-11-tetradecenyl acetate, in the microgram ratio of 65:35:10, were necessary for optimum attraction. Another tortricid moth, Archips griseus, was attracted to some of the aldehyde mixtures.
