Abstract:

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.
