2010-2012年对云南省普洱市茶黑毒蛾Dasychira baibarana Matsumura的发生规律开展了系统调查,结果表明,茶黑毒蛾在云南普洱市一年发生5代,6-10月为茶黑毒蛾幼虫的发生高峰期,3-4代为主害代。茶黑毒蛾幼虫历期以第1代最长,平均33-34 d,其次是第5代,平均为26 d。第2、3、4代幼虫历期为20-21 d。7-9月为茶黑毒蛾成虫的主要发生期。此外,研究发现,根据茶园茶黑毒蛾的发蛾高峰日,采用历期法预测防治时期基本可行,可按照预测的时间进行防治或适当提前进行防治。
A systematic investigation was carried out on the occurrence of Dasychira baibarana Matsumura in Pu’er City, Yunnan Province from 2010 to 2012. The results showed that the occurrence of Dasychira baibarana Matsumura in Pu’er City of Yunnan Province occurred for 5 generations in a year, Peak, 3-4 generations of the main victims. The duration of larvae was the longest in the first generation with an average of 33-34 days, followed by the fifth generation with an average of 26 days. The 2nd, 4th, 4th larvae lasted for 20-21 days. July-September is the main occurrence period of the adult black moth. In addition, the study found that, according to the peak day of the hair moth of tea garden black moth, it is basically feasible to predict the period of prevention and control using the period method, and the prevention and treatment can be carried out according to the predicted time or the prevention and treatment can be carried out in advance.
