茶毛虫性信息素对茶毛虫防治效果研究

The control Effectiveness of Tea Tussock moth（Euproctis pseudoconspersa）with Synthetic Sex Pheromone by Mass Trapping

在贵州湄潭茶场和平坝茶场研究了茶毛虫性信息素引诱剂大面积诱杀茶毛虫的效果，结果表明，茶毛虫性信息素引诱剂以B型效果最好，42天内两地每盆每晚平均可诱到3.41头和7.51头，最高可诱到198头，大面积使用区内茶毛虫雌蛾怀卵量比对照区减少93.50%，卵块减少85.21% ，幼虫数量减少81.15%，说明茶毛虫性信息素引诱剂诱蛾效果非常明显。

The synthetic sex pheromone of tea tussock moth（Euproctis pseudoconspersa）was tested by mass trapping for controlling tea tussock moth in Meitan and Pingba tea plantation of Guizhou province in 2001. The results showed the maximal trap caught of tea tussock moth was observed in the B type of synthetic sex pheromone, which catch the averages of 3.41 males and 7.51 males of tea tussock moth per trap everyday during 42 days in Meitan and Pingba tea plantation, respectively. The numbers of females with eggs, eggs and larvae of tea tussock moth were decreased 93.50%， 85.21% and 81.15% in control tea plantation by mass trapping compared with check tea plantation, respectively. Our results suggested that the efficacy of the synthetic sex pheromone for controlling tea tussock moth was obvious.
