摘要
应用茶毛虫、茶细蛾性引诱剂在重庆、云南、河南、湖北等省茶区进行田间诱蛾试验。结果表明,性诱剂分别对茶毛虫(♂)、茶细蛾(♂)具有较强的引诱活性。通过在重庆和河南的茶园调查显示,使用性引诱剂诱杀成虫后,茶毛虫幼虫数量平均下降79.81%、76.83%;在重庆地区,第2、3代茶细蛾每平方米幼虫比空白对照区平均下降了98.67%。性引诱剂的应用,减少了靶标害虫的田间落卵量以及后代幼虫的数量,防治效果明显。
Field trapping trials was made using sex pheromone of Euproctis pseudoconspersa and Caloptilia theivora in Chongqing,Yunnan,Henan,Hubei province and so on.The results showed that the sex pheromone had strong attractive activity to Euproctis pseudoconspersa（♂） and Caloptilia theivora（♂）.In tea garden of Chongqing and Henan,the investigation showed that after using sex pheromone trapping adults,the number of Euproctis pseudoconspersa larvae decreased 79.81 %,76.83 %;in the Chongqing area,the second and third generation larvae of Caloptilia theivora per square meter decreased by an average of 98.67 % than the control area. The application of sex pheromone,reducing the egg and larva amounts of the target pest in area,controlling effects was obvious.
