摘要
为评估防蛾灯对茶园主要蛾类害虫的防控效果,于2021年在贵州瓮安县和四川邛峡市两个地区的茶园开展防蛾灯防控效果评估.结果表明,贵州瓮安县茶园的茶尺蠖和茶毛虫每调查日的平均防效均在70%以上,茶尺蠖的最高防效达91.67%,茶毛虫的最高防效为93.77%.四川邛峡市茶园,茶尺蠖、茶毛虫和茶细蛾3种蛾类害虫在大部分调查日的防效在50%以上,平均最高防效分别达65.33%、66.67%、80.00%.距离光源不同调查点之间的防效差异显著分析显示,贵州瓮安县茶园在5、10m和15m之间差异不明显,四川邛峡市茶园在大部分调查 日期差异明显,距离光源越近防效越好.该研究结果为防蛾灯在茶园的应用和推广提供了必要的参考依据.
Abstract
This study aimed to evaluate the effectiveness of yellow light in controlling major moth pests in tea gardens.The experiments were conducted in Weng'an County of Guizhou Province and Qiongxia City of Sichuan Province in 2021.The results showed that the yellow light had a significant impact on controlling Ectropis oblique subsp.hypulina Wehrli and Euproctis pseudoconspersa Strand in tea gardens in Weng'an County.The average control effect was over 70%per survey day,with the highest control effectiveness for Ectropis oblique subsp.hypulina Wehrli being 91.67%and for Euproctis pseudoconspersa Strand being 93.77%.In the tea gardens of Qiongxia City,Sichuan Province,the control effects of the three kinds of moth pests,namely Ectropis oblique subsp.hypulina Wehrli,Euproctis pseudoconspersa Strand,and Caloptilia theivora Walsingham were more than 50%on the survey day.The average highest control effect was 65.33%,66.67%,and 80%,respectively.There was not much difference in the control effect at positions 5 meters,10 meters,and 15 meters away from the light source in the tea gardens of Weng'an County,Guizhou.However,in the tea gardens of Qiongxia City,Sichuan,the difference was quite obvious on most survey dates.The closer the tea plants are to the light source,the better the control effect.The research results provided essential experimental evidence for the application and promotion of yellow light in tea gardens.
