摘　　要：为探索灰茶尺蠖性信息素诱捕器在闽北乌龙茶区最佳悬挂密度及其对后代幼虫的防治效果,设置每667 m^(2)茶园放置2套、4套、6套诱捕器和不放置诱捕器等不同处理,调查各处理下灰茶尺蠖成虫诱集数量和后代幼虫种群数量。试验结果表明,不同悬挂密度下诱捕器平均诱虫数量为(14.33±5.24)头/周,4次调查诱捕害虫总数达到102头;其中,以每667 m^(2)放置4套诱捕器为闽北乌龙茶茶园灰茶尺蠖性信息素诱捕器的最佳悬挂密度,最佳悬挂密度处理区内的第一代幼虫种群数量最低,平均为(2.00±0.58)头,而CK为(4.33±1.86)头。In order to explore the best hanging density of sex pheromone trap for Ectropis grisescens in the Oolong tea field in northern Fujian,the control effects of 0,2,4,6 sets of traps per 667 m^(2) tea gardens on the number of adults and first generation larvae were compared.The results show that the average number of insects caught by the traps under different hanging densities was(14.33±5.24)heads/week,and the total number of trapped insects reached 102 in 4 surveys.Among them,treatment of 4 sets of traps per 667 m^(2) had the best effect.The number of the first generation larvae under treatment of four traps per 667 m^(2) was the lowest,with an average of(2.00±0.58)larvae,while CK was(4.33±1.86)larvae.
