Laboratory Biology, Immature and Adult Morphology of Trichopria drosophilae (Perkins) (Hymenoptera: Diapriidae), Parasitoids of Drosophila Flies

open access: yesEntomologia 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 ...

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

open access: yesEcological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...
