摘要
[目的]探讨马铃薯薯块挥发物对马铃薯块茎蛾的引诱效果。[方法]利用Y型嗅觉仪测定马铃薯块茎蛾成虫对自然贮存不同时间(0、15、30、45、60d)完整的和切开的马铃薯块茎挥发物的嗅觉行为反应。[结果]不论是新鲜的还是放置不同时间的完整马铃薯块茎释放出的气味对马铃薯块茎蛾雌、雄虫均无显著引诱效果。剖开的新鲜马铃薯块茎能显著引诱已交配雌蛾,但对处女雌蛾和雄蛾无显著引诱效果。室内自然放置15d以上的马铃薯块茎被切开后所产生的气味不能显著引诱雌、雄两性成虫。剖开的新鲜马铃薯块茎气味不能显著加强雌性信息素对雄虫的引诱效果。[结论]剖开的新鲜薯块挥发物对马铃薯块茎蛾雌虫有显著的产卵引诱效果,但对两性成虫的交配行为无影响。
[ Objective ] The research aimed to explore the attractant effect of volatiles from potato tubers to Phthorimaea operculella. [ Method ] The olfactory behavioral responses of P. operculella adult to the volatiles from intact and cut potato tubers in natural storage of different time （0, 15, 30, 45 and 60d） were determined by using Y-tube olfactometer. [ Result] The odor released from intact potato tuber whether it was fresh or placed in different time had no obvious attractant effect on both male and female P. operculella. The cut fresh potato tuber could seduce the mated female moths significantly, but had no evident attractant effect on virgin female and male ones. The odor produced from cut potato tubers that placed over 15d indoor could not significantly attract male and female adults. The smell from the cut fresh potato tuber was not able to strengthen the female sex pheromone on attractant effect to male worms. [ Conclusion] The volatiles from cut fresh potato tubers had obvious oviposition attractant effect to P. operculella female moth, but no influence on mating behavior of male and female adults.
