摘　　要：为明确豫南茶园中茶毛虫年发生代数和各代成虫发生高峰期,摸清茶毛虫的发生规律,2019—2021和2023年利用性信息素诱捕器监测了信阳市茶园中茶毛虫的发生动态。调查结果发现,2019、2020年发生2代,2021年发生不完全3代,2023年发生3代;第1代、第2代和第3代的成虫发生高峰期分别在6月中下旬、8月中下旬和11月上旬。茶毛虫成虫发生量在不同年份之间存在显著差异,4年成虫年诱捕量分别为80.6、50.2、36.0和488.0头/台;其中2023年最多,第1代、第2代和第3代成虫诱捕量分别为50.8、61.4和264.9头/台。茶毛虫成虫年发生量在各个茶园中存在显著差异。平地茶园的年发生量高于丘陵茶园,信阳群体种的年发生量多高于薮北品种。本研究明确了豫南茶园中茶毛虫的年发生代数、成虫发生量和各代成虫发生高峰期,对茶毛虫的准确预测预报及绿色防控措施的制定具有重要意义。The objective of this study was to clarify the annual occurrence of generations of Euproctis pseudoconspersa and the peak period of each generation in tea plantations in southern Henan Province,as well as to find out its occurrence pattern.To achieve this,sex pheromone traps were used to monitor the occurrence dynamics of E.pseudoconspersa in tea plantations in Xinyang City in 2019-2021 and 2023.The results showed that two generations occurred in 2019 and 2020.three incomplete generations occurred in 2021,and three generations occurred in 2023.The peak periods for the first,second,and third generations of adults were observed to be in mid-late June,mid-late August,and early November,respectively.There were significant differences in the number of adults across different years.In 2019,2020,2021,and 2023,the annual occurrence of adults was recorded,with a mean of 80.6,50.2,36.0,and 488.0 per trap,respectively.The largest number of adults was recorded in 2023,with 50.8,61.4,and 264.9 individuals per trap in the first,second,and third generations,respectively.There were significant differences in the annual occurrence of adults in various tea plantations.The annual occurrence of E.pseudoconspersa was higher in tea plantations situated in the plain than in those located in hilly areas.Additionally,the annual occurrence of E.pseudoconspersa in the Xinyangqunti variety was larger than that in the Soubei variety in most cases.In this paper,the number of annual occurrence generations,the number of adults,and the peak of each generation of E.pseudoconspersa in tea plantations in southern Henan Province are clarified,which is of great significance for accurately predicting and forecasting E.pseudoconspersa populations and for developing green control measures.
