Journal of the Royal Society Interface, 2020 Nectar is a common reward provided by plants for pollinators. More concentrated nectar is more rewarding, but also more viscous, and hence more time-consuming to drink.

Air pollution and its multifaceted effects on insect pollinators: A review
Ecological Entomology, EarlyView.Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.

Gyne and drone production in bombus atratus (Hymenoptera: Apidae) [PDF]
, 2017 For over a decade, our research group has studied the biology of the native bumblebee, Bombus atratus, to investigate the feasibility of using it to pollinate crops such as tomato, strawberry, blackberry and peppers.

Insect Conservation and Diversity, EarlyView.Across 12 farmland sites, we deployed wild bee traps in deciduous woodland canopies and understories, and in an open habitat (at field margins) before and after canopy closure. Post‐canopy closure, understory activity (relative to field margins) generally decreased, but higher temperatures may have increased its likelihood.

Feeding frequency and caste differentiation in Bombus terrestris larvae [PDF]
Insectes Sociaux, 1999 The frequency with which bumble bee larvae are fed during their development was studied using video-recordings. The behaviour of the workers while feeding worker, male and queen larvae of Bombus terrestris was recorded. At the beginning of development, female larvae of both castes were fed at a similar frequency.

Discriminations of Color and Pattern on Artificial Flowers by Male and Female Bumble Bees, \u3ci\u3eBombus Impatiens\u3c/i\u3e (Hymenoptera: Apidae) [PDF]
, 2018 This study examined the performance of male bumble bees (Bombus impatiens) in color and pattern discriminations and compared it to that of female bees. Bees were trained to forage from rewarding (S+) and unrewarding (S-) artificial flowers which differed

Insect Conservation and Diversity, EarlyView.Wild bee functional groups consist of species that are grouped together based on their similarity in multiple nesting and foraging traits. These functional groups have their own specific association with suitable habitats and urban or agricultural landscapes.

Greenhouse bumblebees (Bombus terrestris) spread their genes into the wild [PDF]
Conservation Genetics, 2010 Bumblebees (Bombus spp.) are commonly used for greenhouse pollination of tomatoes and other crop plants. The colonies used for this purpose are provided by commercial bumblebee breeders, which by now operate at a professional company level. As a result of this practice commercially bred bumblebee colonies are transported and used over large distances ...

Space use of bumblebees (Bombus spp.) revealed by radio-tracking. [PDF]
PLoS ONE, 2011 Accurate estimates of movement behavior and distances travelled by animals are difficult to obtain, especially for small-bodied insects where transmitter weights have prevented the use of radio-tracking.Here, we report the first successful use of micro ...
