The Puzzle of Partial Resource Use by a Parasitoid Wasp [PDF]
The American Naturalist, 2015 When there is conspicuous under-exploitation of a limited resource, it is worth asking what mechanisms allow presumably valuable resources to be left unused? Evolutionary biologists have generated a wide range of hypotheses to explain this, ranging from interdemic group selection to selfishly prudent individual restraint.

Characterizing virulence differences in a parasitoid wasp through comparative transcriptomic and proteomic. [PDF]
BMC GenomicsBackground: Two strains of the endoparasitoid Cotesia typhae present a differential parasitism success on the host, Sesamia nonagrioides. One is virulent on both permissive and resistant host populations, and the other only on the permissive host. This interaction provides a very interesting frame for studying virulence factors.

Parasitoid Wasp Community Dynamics in Vineyards Following Insecticide Application
Frontiers in Environmental Science, 2022 In order to integrate parasitoid wasps in agroecosystems as biological control agents, we need to understand how insecticides affect the parasitoids in the crops and their surroundings.

Diversity of parasitoid wasps in conventional and organic guarana (Paullinia cupana var. sorbilis) cultivation areas in the Brazilian Amazon [PDF]
Acta Amazonica, 2019 We surveyed parasitoid wasps (Hymenoptera) in two guarana plantations in the central Brazilian Amazon (one conventionally, and one organically managed), as well as in adjacent forest and edge areas between crop and forest.

High hemocyte load is associated with increased resistance against parasitoids in Drosophila suzukii, a relative of D. melanogaster. [PDF]
PLoS ONE, 2012 Among the most common parasites of Drosophila in nature are parasitoid wasps, which lay their eggs in fly larvae and pupae. D. melanogaster larvae can mount a cellular immune response against wasp eggs, but female wasps inject venom along with their eggs

The Unconventional Viruses of Ichneumonid Parasitoid Wasps
Viruses, 2020 To ensure their own immature development as parasites, ichneumonid parasitoid wasps use endogenous viruses that they acquired through ancient events of viral genome integration. Thousands of species from the campoplegine and banchine wasp subfamilies rely, for their survival, on their association with these viruses, hijacked from a yet undetermined ...

Take-off mechanisms in parasitoid wasps [PDF]
Journal of Experimental Biology, 2017 High speed video analyses of the natural behaviour of parasitoid wasps revealed three strategies used to launch themselves into the air. Which strategy is the most energy efficient? In Pteromalus puparum, 92% of take-offs by were propelled entirely by movements of the middle and hind legs which were depressed at their coxo-trochanteral and extended at ...

Similar Is Not the Same – Mate Recognition in a Parasitoid Wasp [PDF]
Frontiers in Ecology and Evolution, 2021 Finding and recognizing a suitable mate is a key prerequisite to reproductive success. Insects often recognize prospective mates using chemical cues and signals. Among these, cuticular lipids commonly serve for mate recognition at close range. The lipid layer on the surface of insects is comprised predominantly of cuticular hydrocarbons (CHCs), though ...

Does Bacillus thuringiensis have adverse effects on the host egg location by parasitoid wasps? [PDF]
Revista Brasileira de Entomologia, 2018 This study investigated the interaction between two pest biological control agents, the parasitoid wasp Trichogramma pretiosum (Hymenoptera: Trichogrammatidae) and the entomopathogen Bacillus thuringiensis (Bacillales: Bacillacea) (Bt).
