<i>Bombus terrestris</i> Complementary Sex Determiner (BtCSD) is identified as a conserved hymenopteran sex determination region: evolution, breeding, and conservation implications Open
All Hymenoptera (bees, sawflies, ants, wasps) are haplodiploid. Haploid males develop from unfertilized eggs and diploid females from fertilized eggs. Many species also have single locus complementary sex determination (sl-CSD): hemizygosi…

Climate Change Influences on Central European Insect Fauna over the Last 50 Years: Mediterranean Influx and Non-Native Species Open
The Central European fauna, in the last decades, has been undergoing a strong transformation due to four main factors: the retreat of living organisms that require cool and wet habitats, the proliferation of organisms that thrive in warm a…

Examining the effects of repeated pesticide exposure on bumblebee queen survival and reproduction Open
Bees are key pollinators, and thus declines in their populations around the world may lead to negative consequences for both the environment and agricultural systems. While these declines are caused by multiple factors, the use of pesticid…

No impact of cyantraniliprole on the hibernation success of bumble bees (<i>Bombus terrestris audax</i>) in a soil‐mediated laboratory exposure study Open
Increasing evidence shows that wild bees, including bumble bees, are in decline due to a range of stressors, including pesticides. Our knowledge of pesticide impacts has consequently grown to enable the design of increasingly realistic ris…

Potential costs of learning have no detectable impact on reproductive success for bumble bees Open
Development and maintenance of neural architecture supporting learning and memory, as well as active storage of learnt information, are predicted to carry significant energetic costs. Here we explored whether the demands of learning about …

Changes in Population Densities and Species Richness of Pollinators in the Carpathian Basin during the Last 50 Years (Hymenoptera, Diptera, Lepidoptera) Open
Temporal changes in population densities and species richness of three main pollinator groups—moths and butterflies (Lepidoptera); bees, wasps and sawflies (Hymenoptera); and hoverflies, horseflies, tachinids and bee flies (Diptera)—were i…
