Venom Proteins from Parasitoid Wasps and Their Biological Functions

Toxins, 2015
Parasitoid wasps are valuable biological control agents that suppress their host populations. Factors introduced by the female wasp at parasitization play significant roles in facilitating successful development of the parasitoid larva either inside ...

A novel negative-stranded RNA virus mediates sex ratio in its parasitoid host. [PDF]

PLoS Pathogens, 2017
Parasitoid wasps are important natural enemies of arthropod hosts in natural and agricultural ecosystems and are often associated with viruses or virion-like particles.

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]

, 2014
Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

Visualization of Polydnavirus Sequences in a Parasitoid Wasp Chromosome [PDF]

Journal of Virology, 2002
ABSTRACT Polydnaviruses, obligatorily associated with endoparasitoid wasps, are unique in that their segmented genome is composed of multiple double-stranded DNA circles. We present here the first cytological evidence that virus segments are integrated in the wasp genome, obtained by using in situ hybridization of virus probes with viral ...

Recombination and its impact on the genome of the haplodiploid parasitoid wasp Nasonia [PDF]

, 2013
Homologous meiotic recombination occurs in most sexually reproducing organisms, yet its evolutionary advantages are elusive. Previous research explored recombination in the honeybee, a eusocial hymenopteran with an exceptionally high genome-wide ...

Ovipositor characteristics differ between two parasitoids (Hymenoptera, Figitidae) of Drosophila suzukii (Diptera, Drosophilidae) in an adventive landscape [PDF]

Journal of Hymenoptera Research, 2023
Different ovipositor characteristics among parasitoid species that share similar niches are associated with different wasp life histories and selective pressures.

The transcriptomic basis of oviposition behaviour in the parasitoid wasp Nasonia vitripennis [PDF]

, 2013
Linking behavioural phenotypes to their underlying genotypes is crucial for uncovering the mechanisms that underpin behaviour and for understanding the origins and maintenance of genetic variation in behaviour.

Circadian Activity and Clock Genes in Pachycrepoideus vindemmiae: Implications for Field Applications and Circadian Clock Mechanisms of Parasitoid Wasps

Insects, 2023
Despite the importance of circadian rhythms in insect behavior, our understanding of circadian activity and the molecular oscillatory mechanism in parasitoid wasp circadian clocks is limited.

Parasitoid load affects plant fitness in a tritrophic system [PDF]

, 2008
Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont ...

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 ...
