摘　　要：2019—2023年每年的2月下旬至11月下旬在四川雅安市名山区3个茶树主栽品种‘名山特早213’‘福鼎大白茶’‘名山白毫131’茶园内,采用性诱捕器和检叶法对茶细蛾成虫和幼虫发生动态进行监测,每7 d调查1次,并于2021年开展性引诱剂对茶细蛾防治效果试验。调查结果发现,茶细蛾在当地茶园每年发生6代,以蛹越冬。成虫最早始见于2月下旬,终见于11月下旬。越冬代成虫羽化盛期为3月中、下旬至4月上、中旬,第1代为5月上、中旬至6月上旬,第2代为6月下旬至7月上旬,第3代为7月下旬至8月上、中旬,第4代为8月下旬至9月上、中旬,第5代为9月下旬至11月上、中旬。幼虫最早始见于3月中旬,第1代和第2代虫口量极低,第4代或第5代后虫口量显著增加。茶细蛾呈5月至7月和9月至10月两个发生盛期,主要危害夏、秋茶。应用性引诱剂对第2代至第5代幼虫防治效果为55.56%~100%,平均防效为75.92%。应用性引诱剂能有效监测茶细蛾发生动态并控制其危害,适合大面积推广应用。During late February to late November of each year from 2019 to 2023,the occurrence dynamics of adults and larvae of Caloptilia theivora were monitoried by sex pheromone traps and leaf inspection methods in the tea gardens of three main tea varieties Mingshan Tezao 213,Fuding Dabai Cha and Mingshan Baihao 131 in Mingshan District,Ya'an City,Sichuan Province.The investigation was conducted once every 7 days,and an experiment on the control effect of sex pheromone traps on C.theivora was carried out in 2021.The investigation results found that Caloptilia theivora occurs 6 generations per year in the local tea gardens,and overwinters as pupae.Adults first appeared in late February and finally appeared in late November.The peak period of adults of overwintering generation emergence was from middle and late March to early and mid April,the first generation was from early and mid May to early June,the second generation was from late June to early July,the third generation was from late July to early and mid August,the fourth generation was from late August to early and mid of September,and the fifth generation was from late September to early and mid November.The larvae first appeared in mid March,with extremely low population in the first and second generations,and a significant increase in population after the fourth or fifth generation The larvae of Caloptilia theivora has two peak periods of occurrence from May to July and from September to October,which mainly damage summer and autumn tea.The application of sex pheromone has a control effect of 55.56%to 100%on the second to fifth generation larvae,with an average control effect of 75.92%.The application of sex pheromone can effectively monitor the occurrence dynamics of Caloptilia theivora and control their harm,which is suitable for popularization and application in a large area.
