Abstract:
Taking Cacopsyllachinensis as material,conducting in pear orchard,Taigu,Shanxi,respectively in 2012 and 2014,aiming to find the relationship between temperature together with phenology and the development of Cacopsyllachinensis.The results showed that when the average temperature within 6 days was 0℃ in pear orchard (the flower bud of Yuluxiang pear just bloomed in late Feb to early Mar),the overwintering adults started to be active;when the average temperature increased to 8.5℃ (pear flower buds come out in mid to late Mar),the overwintering adults achieved the peak.And this process spent 25 days.Besides,when the average temperature within 6 days was 12℃ (pear flower bloomed in early to mid Apr),overwintering adults achieved the peak of egg production,the time from the beginning to lay eggs to the peak is 18 days;when the average temperature climbed up to 15℃ (80%-90% pear flower fell in late Apr),the first generation of nymphal achieved the peak,and the peak is 18 days after they first showed up.We concluded that the best time for Cacopsyllachinensis control in early spring is the peak time of overwintering adults’ post-hibernation(pear flower buds come out in mid to late Mar) and egg hatching(80%-90% pear flower fell in late Apr).
