桉树枝瘿姬小蜂Leptocybe invasa Fisher & La Salle喜好在桉属（Eucalyptus）植物的新生部位产卵。本研究以尾赤桉为寄主研究其产卵模

式发现，当天羽化且没有产卵经验的雌成虫在经过寄主识别（11687 s）和寄主评估（20827 s）后即进行产卵循环（平均587次），每

个产卵循环产2粒卵，且搜索行为的发生一般伴随产卵位置的变换。在被观察的15头雌成虫中，平均每头产卵1360粒，每次产卵持续1731

s。在产卵过程中，其刺探行为所占总时间的比例和发生频次最大，而静息行为最小。在不同寄主植物间，桉树枝瘿姬小蜂喜好在尾赤桉的叶

柄和叶脉处产卵，且2个部位间无显著性差异，而在尾叶桉、巨尾桉、隆缘桉和小果灰桉上，其喜好在叶柄处产卵且显著大于其它2个部位。

Leptocybe invasa Fisher & La Salle prefer laying eggs on new branches of Eucalyptus plants. The oviposition behavior of this

insect on E. urophylla × E. camaldulensis was investigated. Before comming in  the laying cycle L. invasa must go through a

process of host discrimination and exploration. It can lay two eggs in one cycle, and running or walking while drumming

followed changing in oviposition sites. Based on a sample of 15 female wasps, the average number of eggs per female was 13

60 and the average duration for laying one egg was 1731 s. In the L. invasa laying egg process, the frequency of prying

behavior was significantly higher, and standing behavior was obviously lower, than other behaviors. On E. urophylla × E.

camaldulensis, L. invasa favored laying eggs on petioles and midribs, and there were no significant differences in the

number of eggs laid on these sites, but on E. urophylla, E. grandis ×E. urophylla, E. exserta, and E. propinqua, it

significantly favored petioles to midribs and twigs.
