Gustatory sensitivity to amino acids in bumblebee mouthparts

open access: yesRoyal Society Open Science
Bees rely on amino acids from nectar and pollen for essential physiological functions. While nectar typically contains low (less than 1 mM) amino acid concentrations, levels in pollen are higher but variable (10–200 mM).

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

open access: yesIntegrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

open access: yesAgricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

open access: yesAgricultural 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

EFFICIENCY OF CUCUMBER (Cucumis sativus L.) POLLINATION BY BUMBLEBEES (Bombus terrestris)

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2011
The cucumber crop size depends not only on the cultivar and agrotechnical conditions but also on proper pollination of flowers. The aim of the work was the investigation of the efficiency of bumblebees used in the cultivation of cucumber on the yield ...

Comparing time‐lapse photography and traditional human observation in collecting crop pollinator visitation data Ajastetun valokuvauksen ja perinteisen suoran havainnoinnin vertailu kerättäessä tietoa pölyttäjien kukkakäynneistä viljelykasveilla

open access: yesAgricultural and Forest Entomology, EarlyView.
Time‐lapse photography with commercially available trail cameras provides a competitive alternative to direct human observations for documenting pollinator flower visits, but its performance varies between crops. In apple, the cameras recorded more diverse pollinator assemblages than the human observer due to larger temporal coverage of the camera ...

New data regarding the bumblebee fauna (Hymenoptera: Apidae) of the northern part of Murmansk Region

open access: yesFauna Norvegica
The 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 ...
