Exposure to pesticides is a potential concern for pollinators that may forage on plants containing residues. A key element of estimating dietary risk to pollinators is to determine the nature and amount of food consumed by individuals. Recent efforts have focused on honey bees (Apis mellifera), of which nectar foragers are thought to be at greatest risk of dietary exposure due to their foraging behavior and high energy requirements for the flight-foraging activities. At upper tiers of pesticide ...

The need for basic information on tropical crop pollinators remains a key priority. Here, we used a dataset on Brazilian bee-crop interactions to determine important bee species for crop pollination and discuss their management in Brazilian croplands. We developed an analytical approach to select key bee species and genera from datasets based on different criteria, selecting only interactions reported as effective pollination events. Data on pollination included 261 records of unique crop-pollin...

Brood parasites need to overcome host detection in order to exploit their target resource. Nest invasion by brood parasites is possibly enabled either by chemical mimicry (innate odour match with host), camouflage (acquired odour match with host) and/or chemical insignificance (odour reduction). We analysed which of these strategies may be used by the cuckoo bees Sphecodes monilicornis and S. puncticeps to sneak into the nests of their social Lasioglossum bee hosts. In staged dyadic encounters, ...

This research investigates the development of an attract-and-kill bait for in-hive control of the small hive beetle, Aethina tumida. The control method employs attracting the beetles to an in-hive trap with a feeding attractant/stimulant where a toxicant is delivered by consuming an edible bait. Investigations into mild insecticides led to the use of boric acid. At low doses, boric acid is non-toxic to humans but lethal to insects. This research was designed to identify key compounds that would ...

In an enclosed glasshouse with sucrose provisioned artificial flowers, we observed nectar-foraging bumble bees and honey bees under several resource conditions to determine potential for displacement. Different responses were displayed for varying resource treatments. Overall, bumble bees did not show reduced foraging in the presence of honey bees. When resources were reduced, bumble bees did not change their foraging behavior, whereas honey bees responded by decreasing their visitation rate. Wh...

The Cape honey bee (Capensis) is unusual in that workers can produce viable female offspring via thelytokous parthenogenesis. In contrast, mated queens never reproduce thelytokously, even though they could benefit from doing so when generating daughter queens. Nonetheless, virgin Capensis queens induced to lay without mating by CO2 narcosis produce a high proportion of thelytokous eggs, and instrumentally inseminated queens produce triploid offspring as the result of the fusion of two egg pronuc...

The mechanisms by which pollen is digested by honey bees are incompletely understood. Potential methods are thought to include pseudogermination, mechanical disruption, enzymatic breakdown, or osmotic shock. Understanding the role of pseudogermination in this process has been hampered by a lack of tools demonstrating retention of metabolic activity in pollen collected by honey bees. Here, we show that pollen collected by honey bees produces reactive oxygen species (ROS) at robust levels upon ger...

The aim of this study was to assess potential harmful lethal and sublethal effects of commercial plant protection product containing Bacillus amyloliquefaciens QST 713 (formerly subtilis) spores on winter adult honeybees according to OECD 245 (2017). Caged winter honeybees fed 10 days with a sucrose solution (50% w/w) ad libitum spiked with a maximum application field rate of 1/1 and its 1/10 showed no dose-dependent mortality under laboratory conditions; the No Observed Effect Concentration (NO...

Determining bee flight capacity is crucial for developing management strategies for bee conservation and/or crop pollination and purposes. In this study, we determined the flight distance of the stingless bee Melipona fasciculata using the radiofrequency identification (RFID) technology. For this, we conducted two translocation experiments using workers equipped with RFID microsensors: (1) release of bees at seven distances between 100 and 3000 m from experimental colonies in Belem, Brazil, and ...
