河南信阳地区茶毛虫发生代数研究

Studies on the yearly generations of Euproctis pseudoconspersa in Xinyang Henan Province

通过连续4年的调查研究表明,茶毛虫Euproctis pseudoconspersa Strand在河南信阳茶区年发生3代,而不是过去认为的每年发生2代。第1、2、3代幼虫分别在4月中旬至5月下旬、6月下旬至7月下旬、8月中旬至9月下旬为害茶树。

Four consecutive years of observation and field investigation indicates that the tea tussock moth Euproctis pseudoconspersa Strand produces three generations per year,rather than two,as previously thought,in Xinyang,Henan Province.The first,second and third generation larvae damage tea plants in the middle of April to late May,late June to late July and middle of August to late September,respectively.
