摘要
马尾松毛虫是一种主要林业有害生物,通过黑光灯诱蛾试验对越冬代马尾松毛虫成虫种群进行动态监测,采用t检验法进行样本差异显著性检验,在可靠性95%的情况下差异显著,分析得出羽化盛期为5月24日前后,这段时间为黑光灯诱蛾的最佳时期。
Dendrolimus punctatus is a kind of important forestry harmful organism.The population dynamics of its winter adults was obsreved and surveyed through the experiment of black lights trapping moths.Then,by using the t examination the significance test of sample difference was made.The test results show that under the confidence coefficient of 95% the differece is significent.h can be concluded that its peak emergence peak perional is about the 24th of May,which is the best time to trap moths with black lights.
