A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids
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.

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 ...

In the face of environmental contamination to copper, mainly resulting from frequent copper‐based fungicide applications, it is crucial to understand the side effects of these pesticides on non‐target organisms to improve pest management. Trichogramma cordubensis, used as a biological control agent against grape berry moths in vineyards, shows strongly

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 ...

Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

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.

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.

In central Ukraine, the migratory butterfly Vanessa cardui emerged as a key pest of organic soybean during its outbreaks in 2019 and 2022. Despite early defoliation, crops recovered strongly due to high parasitism by Cotesia vestalis, reaching 100% in some fields.

This field mesocosm study examined the top‐down effects of hyperparasitoids, parasitoids and aphids on plant growth and fitness. Parasitoids reduced aphid populations, but this effect was attenuated by hyperparasitoids. However, these multitrophic interactions did not affect plant traits and reproduction, likely due to the plant's fast life cycle and ...
