TL;DR: Results show that short exposure to an elevated temperature, which is frequently experienced by parasitoids during the summer, resulted in high mortality rates in a parasitoid population and strongly affected the fitness of survivors by drastically reducing reproductive output and triggering a sex-dependent effect on lifespan.

TL;DR: It is demonstrated that populations showing low diapause levels may recover higher levels through transgenerational plasticity in response todiapause-induction cues, provided that environmental conditions are reaching the induction-thresholds specific to each population.

TL;DR: Using a nine-year dataset of aphid-parasitoid winter trophic webs in cereal fields of Western France, it is reported that the community structure and composition that prevailed before 2011 have recently shifted toward a more diversified community, with the presence of two new braconid parasitoid species.

TL;DR: This experiment is the first to test the effect of arrival order on patch exploitation strategies in nonfighting species, and confirms the theoretical prediction: first-arriving females stay longer on a patch of hosts than second-arrived females.

TL;DR: The results showed that the cues used for interspecific host discrimination depend on the specific identity of the interaction, and these differences seemed strongly linked to the way the different species respond to defensive behaviours of their aphid hosts.
