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

open access: yesInsect 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

open access: yesInsect 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.

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

open access: yesInsect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Effects of Early Season Temperature on Adult Life History Traits of Wheat Stem Sawfly, Cephus cinctus (Hymenoptera: Cephidae) and Bracon cephi (Hymenoptera: Braconidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), is a long‐standing and serious pest of wheat, Triticum aestivum Linnaeus (Poaceae), in the northern Great Plains region of North America. Over the last decade, research efforts have aimed to better understand C.

Floral Trait Influence on the Foraging Decisions of a Fly Pollinator

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flies foraging for floral resources provide important ecosystem services through the pollination of myriad angiosperms, including many crop species. However, the specific floral cues used by fly pollinators to locate and discriminate among floral rewards and the preferences they may have for specific cues remain poorly understood.
