The effect of competition on oviposition decisions of Leptopilina heterotoma (Hymenoptera: Eucoilidae)
Article Abstract:
Insect parasitoids, Leptopilina heterotoma, can distinguish between unparasitized, once parasitized by a cospecific, once parasitized by the female herself and twice parasitized hosts. Those which are less profitable are rejected in the foraging bout only to be accepted later on leading to partial preferences. Sometimes some prey types are rejected and accepted even within the same foraging bout. However in the absence of competition, there is no change of behaviour among the parasitoids.

Oviposition and incubation environmental effects on embryonic diapause in a ground cricket
Article Abstract:
Maternal influence on the incidence of diapause among laid eggs was investigated to determine the ability of the female ground cricket, Allonemobius socius, to transmit climate information to her brood. Environmental manipulation in both maternal and egg abiotic environment were undertaken in the investigation. Results reveal that maternal environment has little contribution over the incidence of diapause. The implications of these findings are discussed.

Worker oviposition and policing behaviour in the myrmicine ant Aphaenogaster symthiesi japonica Forel
Article Abstract:
The worker policing behavior of the myrmicine ant Aphaenogaster smythiesi japonica, in which queen and worker castes are morphologically distinguishable and differ in reproductive functions, are observed. The results indicate that worker policing potentially inhibits the workersE production of males in this species, contrary to the prediction that worker policing is not predominant in monogynous and monandrous societies.
