Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Local habitat, not landscape diversity, drives richness and reproduction of cavity‐nesting bees and wasps in agricultural landscapes

Insect Conservation and Diversity, EarlyView.
Local habitat type and hedgerow cover strongly shape bee and wasp richness, but only weakly their reproductive output, outweighing the landscape diversity effects at the 1‐km2 scale. Forests host more wasp but fewer bee species, whereas orchards support high richness of both; bee reproduction patterns are driven by one dominant species, while wasp ...

Declining habitat directive butterflies within a major stronghold: Challenges for conservation Rückläufige Tagfalter der FFH‐Richtlinie in einer bedeutenden Hochburg: Herausforderungen für den Naturschutz

Insect Conservation and Diversity, EarlyView.
Myrmecophilous Phengaris nausithous and P. teleius are highly specialized grassland butterflies and flagship species for European nature conservation, but they exhibit ongoing population declines. We show strong declines for both species in the Westerwald mountain range, western Germany, since 1994, driven by inappropriate timing of mowing, grassland ...

Food resources are more important than nesting resources for explaining wild bee diversity in urban gardens Nahrungsressourcen haben einen größeren Einfluss auf die Wildbienendiversität in urbanen Gärten als das Nistangebot

Insect Conservation and Diversity, EarlyView.
Urban community gardens showed a high wild bee diversity with 168 recorded species, representing roughly 30% of Germany's wild bees, including threatened species like Osmia mitis and Coelioxys lanceolata. Floral resources, not nesting resources or habitat availability, were the main drivers for wild bee taxonomic and functional diversity.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.
