【摘要】The actual emission rates and their relative ratios of multi-component pheromone blend of the normal and mutant cabbage looper moth from rubber septa were determined by analyzing the extracts of airborne collection in Gas Chromatography-Mass Spectrometry. Dodecyl and dodecenyl acetates emitted significantly faster than tetradecenyl acetates from the septum containing these two groups of acetates at equal amounts. The emission rate increased with the increase of loading dosage, but reach its maximum at 100 μg. Emission rates of all pheromone components decreased dramatically after baits were exposed for one week. Frozen-stored pheromone baits decreased their emission rates of pheromone compounds starting from the second day, conpared to those of fresh ones. There was no increase in male behavioral response of male mutants towards the elevated mutant pheromone bait, which was equivalent to what a mutant female produced. But the normal nale cabbage looper moths do prefer to the pheromone bait emitted less amount of Z9-14:OAc. The influence of release rates on mating disruption was also discussed.%用空气收集法收
