| Abstract: | After systemic investigation,it is preliminary revealed that the Pealius mori Takahashi occurs 8 generations in Wujiang city,Jiangshu Province.At average daily temperature 26.6～27.9 ℃,the average developmental duration of adults,eggs,larvae and pupae of Pealius mori Takahashi is 3.2,4.5,16.5 and 5.7 days respectively,the whole generation is about one month.The sex ratio of female to male is 12.3∶1.The grownth and development law is determined by climate,natural enemy and prevention.For the first time,we have found the natural enemy Eretmocerus longipes Compere of Pealius mori Takahashi in the research. |
