Genomic analysis reveals an exogenous viral symbiont with dual functionality in parasitoid wasps and their hosts.

PLoS Pathogens, 2020
Insects are known to host a wide variety of beneficial microbes that are fundamental to many aspects of their biology and have substantially shaped their evolution.

Estimating some demographic parameters of Aphidius matricariae Haliday (Hymenoptera: Braconidae), the parasitoid of the greenbug aphid, Schizaphis graminum (Rondani) (Hemiptera: Aphididae), at different temperatures

Egyptian Journal of Biological Pest Control, 2020
Some demographic parameters of the indigenous parasitoid, Aphidius matricariae Haliday (Hymenoptera: Braconidae) parasitizing the greenbug, Schizaphis graminum (Rondani) (Hemiptera: Aphididae), were estimated at 3 different temperatures (20, 25, and 30 ±

Evolution of flexible biting in hyperdiverse parasitoid wasps [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2022
One key event in insect evolution was the development of mandibles with two joints, which allowed powerful biting but restricted their movement to a single degree of freedom. These mandibles define the Dicondylia, which constitute over 99% of all extant insect species.

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.

Multi-trait mimicry of ants by a parasitoid wasp [PDF]

Scientific Reports, 2015
Many animals avoid attack from predators through toxicity or the emission of repellent chemicals. Defensive mimicry has evolved in many species to deceive shared predators, for instance through colouration and other morphological adaptations, but mimicry hardly ever seems to involve multi-trait similarities. Here we report on a wingless parasitoid wasp

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.

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.

An Endoparasitic Wasp, Diachasmimorpha longicaudata (Ashmead) (Insecta: Hymenoptera: Braconidae)

EDIS, 2004
Diachasmimorpha (formerly Biosteres or Opius) longicaudata Ashmead (Wharton 1987) is a solitary braconid wasp parasitoid of Caribbean fruit fly, Anastrepha suspensa (Loew), larvae.
