This study exhibits how depletion of nesting substrates combined with increases in urban cover can affect pollinators, a concerning scenario as most bees nest in friable soil and thus are strongly susceptible to urbanization. We emphasize that urban planning policies to protect ground-nesting bees ...
Insect pollinators are threatened by multiple environmental stressors, including pesticide exposure. Despite being important pollinators, solitary ground-nesting bees are inadequately represented by pesticide risk assessments reliant almost exclusively o

Honey bees process nectar into honey by active evaporation on the tongue and passive evaporation involving nest ventilation and fanning behaviour, as well as enzymatic action. The elimination of excess water from nectar carries considerable energetic costs. The concentration of the nectar load is assume...
There are several species of ground-nesting wasps and bees that deserve attention. We're talking about solitary wasps and bees that are not part of a colony, but nest individually (not the social ground-nesting wasps and bees such as yellowjackets and bumble bees). The important things to re...
(Megachilidae:MegachileandRozenapis, and Colletidae:HylaeusandMeroglossa) (Table1). No cleptoparasitic bees emerged. There were 70 above-ground cavity nesting bees collected in the field, and therefore the number of species that were recorded using trap-nests was only 34.3% of bees that could ...
Meliponine colony mortality from predators averaged 12 percent/yr and those near ground were most affected. Tool-using humans and chimpanzees caused 82 percent of stingless bee nest predation. Selective factors affecting nest heights and habit may include auditory hunting by predators for buzzing bees...
Within the test arenas, the presence of colony odour specifically reduced the total recognition errors in honey bees, although this reduction still fell short of bringing error levels down to what was found at the colony entrance. Lastly, in honey bees, the data show that the in-nest ...
Sleep plays an essential role in both neural and energetic homeostasis of animals. Honey bees (Apis mellifera) manifest the sleep state as a reduction in muscle tone and antennal movements, which is susceptible to physical or chemical disturbances. This social insect is one of the most important...
