Abstract：
:Mating in moths is generally mediated by female-produced sex pheromones. Mating activity, female pheromone production/release and male pheromone responsiveness all show diurnal variations in many species. We found that the response of the male Egyptian cotton leafworm, Spodoptera littoralis, to sex pheromone gland extracts showed a diel rhythm in olfactometer tests, and the variation was persistent for at least 1 day in constant darkness. High male response to sex pheromone was correlated in time with high mating and locomotor activity. Male S. littoralis, maintained in constant darkness and exposed to pheromone gland extracts on a daily basis, showed an induced temporal variation in response after several days, in contrast to unexposed males. This suggests that in the absence of other external zeitgebers, exposure to sex pheromone may function to synchronise circadian behavioural rhythms in male moths. The daily rhythm in mating activity in S. littoralis is also shown to be persistent for at least 2 days in constant darkness. Pairs mated significantly less when either the male or female had been raised in a light:dark cycle 10 h out of phase, indicating that the proposed circadian rhythm in mating activity is composed of rhythmic mating preference/ability in both sexes.

abstract：:Endoparasitoid insects have evolved mechanisms to counteract host immune defences. At oviposition, the endoparasitoid Venturia canescens injects virus-like particles (VLPs) together with the egg that interfere with the immune system of the host.
