【摘要】 在风洞中观察了枣镰翅小卷蛾Ancylissativa雄蛾对合成性信息素不同组分 (E9 12∶Ac和Z9 12∶Ac)的行为反应。E9 12∶Ac组分能够引起少量雄蛾 ( 8 3% )完成从兴奋到接触诱芯并呈现交配企图的全部行为反应 ,而雄蛾对Z9 12∶Ac组分无反应。E9 12∶Ac +Z9 12∶Ac混合物中前者占 60 %～ 65%效果最好 ,能使 71 7%～ 76 7%雄蛾到达诱芯并呈现交配企图。E9 12∶Ac与Z9 12∶Ac为 6 5∶3 5时 ,2 0 0ng～2 0 0 0ng的剂量效果最好 ,有 76 7%～ 81 7%雄蛾到达诱芯更多还原

【Abstract】 The behavioural response of individual male Ancylis sativa Liu to synthetic sex pheromone components,E9 12∶Ac and Z9 12∶Ac was observed in a wind tunnel. The lures containing only E9 12∶Ac could stimulate some males (8 3%) to perform all the typical behaviours including exiciting,taking off,flying upwind,landing on the lure and exhibiting their hairpencils,while none of them showed any response to another component, Z9 12∶Ac.71 7%～76 7% of the males displayed their hairpencils in response to the mixture of these two components(E accounting for 60%～65%).The pheromone(E∶Z=6 5∶3 5) from 200 ng to 2 000 ng per lure caused more male response than that of 20 ng or 20 000 ng.更多还原
