Do parasitized caterpillars protect their parasitoids from hyperparasitoids? A test of the ‘usurpation hypothesis’ [PDF]
Caterpillars that are attacked by some species of parasitoid wasps are known to survive for several days after the parasitoid larvae emerge and pupate. It has been argued that the behaviour of the parasitized larva is ‘usurped’ by the parasitoid and that

A molecular detection approach for a cotton aphid-parasitoid complex in northern China
Aphid-parasitoid interactions have been widely used as a model system in research studies on the structure and functions of arthropod food web. Research on aphid-parasitoid food webs is hindered by their micromorphological characteristics and the high ...

Comparing and contrasting life history and development strategies in the pupal hyperparasitoids Lysibia nana and Gelis agilis (Hymenoptera : Ichneumonidae) [PDF]
Since the concept of the 'niche' was proposed by Hutchinson almost 50 years ago, many researchers have investigated factors that enable species within 'guilds' (i.e., species that exploit a common resource and are likely to compete with one another) to ...

New data on Microgastrinae in Serbia and Montenegro (Hymenoptera: Braconidae) and their hosts
The fauna of Microgastrinae wasps was investigated on the territory of Serbia and Montenegro. Eighteen species were recorded and most of them emerged from the previously identified hosts.

Host location by hyperparasitoids: an ecogenomic approach
It is fascinating that our ecological systems are structured by both direct and indirect species interactions. In terrestrial ecosystems, plants interact with many species of insects that include both harmful herbivores and beneficial natural enemies of herbivores.
