| Abstract: | Leptocybe invasa produces four generations a year in Guangzhou city,lives through the winter as the nymph and pupae,the first generation to 4th generation had the longest life span respectively for 100,64,68 and 133 days.In variable temperature condition,developmental starting point 0.00±0.03℃,effective accumulated temperature 1 776.40 day degrees.In eucalyptus grows areas in south China,the south and west coastal areas of Hainan island happened 5 generations in a year,the central and north of Hainan island,Guangdong province,the central and south of Guangxi municipality,the south of Yunnan province and the south-central coastal of Fujian province happened 4 generations in a year,other areas happened 3 generations in a year. |
