...: Geographic variability of immune responses in moths is species specific and suggests trade-offs with life-history traits. Parasitoid Climate change Geographic variation Immunology Lepidoptera Life-history traits In the last few decades, there has been increasing interest in research...

... by The Company of Biologists Ltd 2015 Summary: We show that venom injection by the jewel wasp to either the subesophageal ganglion or the central complex in the brain is, by itself, sufficient to induce a long-term hypokinetic state in its cockroach prey. Cockroach Wasp Parasitoid Central...

... of dietary protein. We further predicted that this response would enhance the melanization response, a component of the immune system that acts against parasitoids. We challenged the immune system using either tachinid fly parasitoids or a bead injection technique that has been used in studies to simulate...

... parasitoid Parasites, by definition, are organisms that take advantage of their hosts. They do this in many ways, for example through the exploitation of their nutritional resources (e.g. haemolymph, lipid or tissues) and by changing behaviours. From a bio-energetic viewpoint, the host–parasite...

...Roberto Ferrarese; Jorge Morales; Daniel Fimiarz; Bruce A. Webb; Shubha Govind SUMMARY Parasitoid wasps produce virulence factors that bear significant resemblance to viruses and have the ability to block host defense responses. The function of these virulence factors, produced predominantly...

...-hydroxy-4-decanolide Hymenoptera mating behavior Nasonia vitripennis parasitic wasp parasitoid Pteromalidae sex pheromone Parasitic wasps are carnivorous insects that develop by feeding in or on the body of other insects. They play a crucial role in natural and agricultural ecosystems...

... egg parasitoids. Odour from twigs of Pinus sylvestris laden with egg masses of the pine sawfly Diprion pini attracts the eulophid egg parasitoid Chrysonotomyia ruforum. Volatiles released from pine twigs without diprionid eggs are not attractive. Oviposition by the sawfly onto pine needles induces...

...J. M. Schmidt; J. J. B. Smith ABSTRACT The parasitoid wasp Trichogramma minutum Riley (Hymenoptera: Chalcidoidea: Trichogrammatidae) adjusts its progeny allocation and host examining behaviour to the exposed volume of its host – an insect egg. The female wasp examines a potential host by walking...

...J. M. Schmidt; J. J. B. Smith ABSTRACT The parasitoid wasps of the genus Trichogramma use the surface curvature of their insect egg hosts to set an upper limit to the number of progeny allocated to the host, as well as the duration of their host examination. In addition, host recognition and host...
