摘要
通过对比分析近两年黑光灯诱蛾量和田间调查幼虫发生动态,并结合越冬试验,明确了二点委夜蛾在鲁西南地区发生世代情况。结果表明:二点委夜蛾在鲁西南地区可以越冬,一年发生4代。
By comparing and analyzing the capture numbers with light traps and larval dynamics investigated in the fields, and combining with the wintering test, the generations of.4thetis lepigone in the Southwest region of Shangdong were studied.
