New data regarding the bumblebee fauna (Hymenoptera: Apidae) of the northern part of Murmansk Region
Fauna NorvegicaThe focus of this study is to present new data regarding the bumblebee fauna of the northern part of Murmansk Region (Northern European Russia). A total 15 species of bumblebees were found here that cover almost all species that may be found in the ...

The dual crisis: Climate change simultaneously drives pollinator decline and Pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Causes of rarity in bumblebees
, 2005 Many bumblebee (Bombus) species are thought to have declined in abundance in the last 50 years, while a small number of species remain abundant. Here we examine which factors render some British bumblebee species more susceptible to environmental change ...

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Acta Agrobotanica, 2014 This study was an attempt to show synanthropic phytocoenoses of the city of Lublin which are potentially valuable to pollinating insects such as bumblebees. B. terrestris and B. lapidarius as well as B. lucorum, B. hypnorum and B. pascuorum were found to

Entomologia Experimentalis et Applicata, EarlyView.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 ...

SOCIAL INFORMATION USE IN SOCIAL INSECTS [PDF]
, 2014 Social learning plays a valuable role in the lives of many animal taxa, sometimes allowing individuals to bypass the costs of personal exploration. The ubiquity of this behaviour may arise from the fact that learning from others is often underpinned by ...

Journal of Apicultural Science, 2016 Due to fewer bumblebees in rural areas these days, it is necessary to look for alternative habitats for the active protection of these very important pollinators.

Entomologia Experimentalis et Applicata, EarlyView.Lethal (mortality) and sublethal (fecundity, fertility) effects of the biopesticide Prev‐Am Plus (containing ~6% sweet orange essential oil) were assessed on the tachinid fly Exorista larvarum. Mated females were exposed via contact and oral routes across five concentrations (0.25%–20%) using protocols adapted from Apis mellifera.
