European Journal of Entomology, 2015 The Asian chestnut gall wasp (ACGW), Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), is a global pest of chestnut trees. This pest was first recorded in Slovenia in 2005.

Entomologia Experimentalis et Applicata, EarlyView.In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids
Entomologia Experimentalis et Applicata, EarlyView.We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

Wolbachia Infection in a Natural Parasitoid Wasp Population
PLOS ONE, 2015 The maternally transmitted bacterium Wolbachia pipientis is well known for spreading and persisting in insect populations through manipulation of the fitness of its host. Here, we identify three new Wolbachia pipientis strains, wHho, wHho2 and wHho3, infecting Hyposoter horticola, a specialist wasp parasitoid of the Glanville fritillary butterfly.

Entomologia Experimentalis et Applicata, EarlyView.In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

Entomologia Experimentalis et Applicata, EarlyView.This study investigates the laboratory biology and morphology of the parasitoid Trichopria drosophilae, which targets Drosophila flies, including the invasive Drosophila suzukii. Key findings include a detailed description of the parasitoid's egg, three larval instars, and pupal stage, as well as unique behaviors such as siblicide and encapsulation in ...

Entomologia Experimentalis et Applicata, EarlyView.We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.

Entomologia Experimentalis et Applicata, EarlyView.Temperature is an important factor to determine the activity of insects. We tested the performance of the non‐native larval parasitoid Leptopilina japonica (Hymenoptera: Figitidae) under realistic climatic conditions to improve understanding about its ongoing spread and seasonal abundance.

Scientific ReportsParasitoid wasps serve as natural enemies of numerous insect species; therefore, knowledge of host-parasitoid interactions is fundamental for understanding ecosystems. Each endoparasitoid wasp taxon exhibits a specific host range.
