| 中文摘要: |
| 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。

| From 2010 to 2012, systematic investigation of Dasychira baibarana was carried out in tea field of Yunnan Puer It has been found that D baibarana occurred five generations a year in this area The high peak period of larvae of D baibarana took place from June to October，and the third and fourth generation were the major pestilent generation moths The longest development duration of larvae of D baibarana was the 1st generation，which was 33-34 d at average；The second was the fifth generation，which was 26 d at average And the development duration of larvae of the second, third and fourth generation were between 20 and 21 d The high peak period of adult of D baibarana took place from July to September Furthermore, it was found the peak of emergence of adult of D baibarana could predict the optimum control stage by means of periodic distance, and the larvae of D baibarana were controlled in accordance with the prediction of the time or ahead of the time. |
