摘要
在实验室条件下利用Y型嗅觉仪测试了小菜蛾Plutellaxylostella成虫对多胺的嗅觉反应。结果表明:与蒸馏水对照比较,小菜蛾在交配前和交配后对精胺、亚精胺和腐胺这3种被测的多胺均有明显的趋性反应,但对3种多胺两两之间的选择则无显著差异;在对3种多胺和甘蓝Brassicaoleracea叶汁之间的选择中,除未交配雄蛾对腐胺有明显的趋性(与甘蓝叶汁比较)和交配后雌蛾对甘蓝叶汁有明显的趋性(与精胺比较)外,其他均没有显著差异。表明多胺对小菜蛾具有引诱作用。
Olfactory responses of Plutella xylostella to polyamines were measured using a Y-tube olfactometer in the laboratory. The results indicated that the diamondback moth adults both unmated and mated had an obvious orientation response to the three polyamines tested （spermine, spermidine, and putrescine） compared with distilled water; but no significant difference in their choice between these three polyamines. Except that unmated males had an obvious orientation response to putrescine compared with cabbie had an obvious orientation response to cabbage juice compared with spermine, the orientation response to the three polyamines and cabbage juice. juice and mated male moths had the same
