| 桉树枝瘿姬小蜂在广州1年完成4世代，以幼虫和蛹在虫瘿内越冬，第1代至第4代的历期分别为100天、64天、68天和133天。在变温状态下，发育起点温度4.0408×1015±0.0266℃，有效积温1776.3964日度。在我国华南桉树种植区，海南岛南部和西部沿海地区为年发生5世代区，海南岛中部和北部、广东省全境、广西壮族自治区中南部地区、云南省南部地区和福建中南部沿海地区为年发生4世代区，其他桉树种植区为年发生3世代区。 |

| 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 days, 64 days, 68 days and 133 days. In variable temperature condition, developmental starting point 4.0408 x 1015 + 0.0266 temperature ℃, effective accumulated temperature 1776.3964 day degrees. In eucalyptus grows areas in south China , the Hainan island in the south and west coastal areas happened 5 generations area in a year, Hainan island in the central and north of area, all Guangdong province area, Guangxi municipality in the central and south of area, Yunnan province in the south of area and Fujian province in the south-central coastal areas happened 4 generations area in a year, other areas happened 3 generations area in a year. |
