摘　　要：通过应用性信息素搭配诱捕器探究灰茶尺蠖(Ectropisgrisescens)和茶毛虫(Euproctispseudoconspersa)在信阳地区的虫情发生动态,同时对诱捕器不同放置高度和不同类型的诱捕量进行比较,探讨信阳地区灰茶尺蠖和茶毛虫发生期的发生动态情况以及诱捕器在茶园中应用的技术参数、使用效果等。结果表明:信阳地区灰茶尺蠖有三个发生高峰,分别是6月初开始到6月中下旬、8月中旬到8月末、9月中旬到10月初;茶毛虫有一个大发生高峰(6月中下旬),两个小高峰(8月中下旬和9月中下旬)。诱捕器悬挂高于茶蓬10 cm和15 cm灰茶尺蠖的诱捕量差异显著,高出茶蓬15 cm的诱捕量大于高出茶蓬10 cm的诱捕量。相同高度三角诱捕器和船型诱捕器的诱捕量差异不显著。试验结果为信阳地区灰茶尺蠖的绿色防控提供较好的性诱剂防治时间、诱捕器放置方式选择,以其提高灰茶尺蠖和茶毛虫的防治效果,节约防治成本,提高信阳地区茶叶品质。By using applied pheromones combined with traps,this study explores the dynamics of the occurrence of the Ectropis grisescen and Euproctis pseudoconspersa in Xinyang.At the same time,compares the trapping capacity of different placement heights and types of traps simultaneously,and the occurrence dynamics of the Ectropis grisescen and Euproctis pseudoconspersa during their occurrence period in Xinyang are explored.The technical parameters and effectiveness of the traps used in tea gardens are also discussed.The results showed that there were three peaks of occurrence of the Ectropis grisescen in Xinyang,which were from early June to mid to late June,from mid August to late August,and from mid September to early October;The Euproctis pseudoconspersa has one major peak(mid to late June)and two small peaks(mid to late August and mid to late September).There is a significant difference in the amount of Ectropis grisescen caught by the trap hanging at a height of 10 cm and 15 cm.Overall,the amount of traps suspended at a height of 15 cm above the tea canopy was greater than that suspended at a height of 10 cm above the tea canopy.There is no significant difference in the trapping amount between the same height triangular trap and the boat type trap.The experimental results provide a good time for the green prevention and control of the Ectropis grisescen in Xinyang,as well as the selection of bait placement methods,in order to improve the control effect of the Ectropis grisescen and Euproctis pseudoconspersa,save control costs,and improve the quality of tea in Xinyang.
