为深入了解小地老虎性信息素通讯系统,利用风洞技术测定了小地老虎雄蛾对性信息素各组分及其不同组合的行为反应。结果表明,5种单一组分Z7-12:Ac(A)、Z9-14:Ac(B)、Z11-16:Ac(C)、Z5-10:Ac(D)、Z8-12:Ac(E)只能引起雄蛾兴奋,均不能引起雄蛾向性信息素源定向飞行;当性信息素释放源为二元混合物AB时,能引起15.71%的雄蛾完成从兴奋到搜索释放源,并表现出预交尾的完整行为反应;在同等使用剂量下,三元混合物ABC的引诱效果最好,有40.58%的雄蛾能搜索释放源,26.15%的雄蛾表现预交尾行为。三元混合物ABC在最佳比例(3:1:1)下,制成不同剂量的诱芯进行风洞试验,结果发现剂量为100μg时雄蛾反应最强烈,有29.87%的雄蛾表现预交尾行为,50μg次之,二者间差异不显著(P≥0.05)。
In order to further understand the sexual pheromone communication system of the small earth tiger, the behavioral responses of male tiger moths to sex pheromone components and their different combinations were determined by the wind tunnel technique. The results showed that the five single components Z7-12: Ac (A), Z9-14: Ac (B), Z11-16: Ac (C), Z5-10: Ac E) can only cause male moth excitement, can not cause male moth directional pheromone directional flight; when the sex pheromone release source for the binary mixture AB, can cause 15.71% of the male moths completed excitement to the search release source, At the same dose, the abstraction effect of the ternary mixture ABC was the best, 40.58% of the male moths could search for the release source, and 26.15% of the male moths showed the pre-mating behavior. The results showed that the male moths reacted the most strongly at a dose of 100μg with 29.87% of the male moths pre-mating at the optimum ratio (3: 1: 1) Behavior, 50μg second, the difference between the two was not significant (P> 0.05).
