印楝对假眼小绿叶蝉鸣声通讯影响的研究

采用自行设计的微音监控系统,研究了植物杀虫剂印楝对茶树害虫假眼小绿叶蝉鸣声通讯的影响。结果表明,印楝种子提取物内吸处理茶梢,对假眼小绿叶蝉雄虫的正常鸣声和雌雄虫交尾行为有不同程度的干扰作用,而且,随着处理用印楝种子提取物浓度的升高,影响程度增加。雄虫异常鸣声引发的雌、雄虫间的求偶声很微弱,交尾前雌雄相遇所需时间延长,交尾持续时间缩短。印楝种子提取物喷雾处理茶梢,对假眼小绿叶蝉雄虫鸣声以及雌雄虫间的交尾行为无影响。

Study on the Influence of Neem to Acoustic Communication of Tea Leafhopper Empoasca vitis

Authors studied the influence of neem to acoustic communication of Empoasca Vitis by using the feeble sound monitoring system. The results indicated that, after feeding the tea shoots that systemic treated by neem seed extracts (NSE), the sound of male Empoasca vitis and sexes’ mating behavior were all affected. The higher the concentration of NSE, the bigger the influence was. The courtship sounds between the sexes that induced by male’ abnormal sound were very feeble, and the times using for mate meeting prolonged, their mating behavior lasted for shorter time. After spraying tea shoots with NSE, the acoustic comuunication and mating behavior of Empoasca vitis were not affected.
