New paper "Avenues towards reconciling wild & managed #bee proponents" led by Alex Beaurepaire. Hopefully a useful addition to discussions about the risks posed by managed bees to wild bees, highlighting knowledge gaps that hinder development of evidence-based policies: www.cell.com/trends/ecolo...

While female squash #bees avidly collect pollen from pumpkin/squash #flowers to feed their offspring, other flower visitors (e.g., honey & bumble bees) often groom cucurbit pollen off their bodies because it doesn't pack well into their pollen baskets or meet their dietary needs🎃🐝

Quite a lot of pollen produced by male squash flowers is wasted (~13%). About 9% of the remaining pollen is transferred to stigmas of female flowers to generate seeds & fruits (plant reproduction). The remaining 91% of pollen is available for squash #bee reproduction #Pollinators

Central to Halloween celebrations,🎃s are entirely dependent on insect #pollinators for reproduction. To find out more check out Dr. Susan Chan and my study on pollen partitioning in a Cucurbita crop pollination system with reference to the wild squash #bee: doi.org/10.26786/192... #HappyHalloween

Our results show that effects of #pesticide exposure from residues in soil depend on intrinsic traits of #bumblebee queen physiology and challenge our understanding of how #bees respond to pesticides under environmentally realistic exposure scenarios.

Exposure to the diamine #insecticide cyantraniliprole led to lethal and sublethal post-hibernation effects that were dependent on #bumblebee queen size, with larger queens showing higher mortality rates, delayed emergence of their first brood, and producing smaller workers.

We found that exposure to boscalid fungicide residues in soil doubled the likelihood of #bumblebee queens surviving through the colony initiation period (after successful hibernation) and laying eggs.

We exposed #bumblebee (Bombus impatiens) queens to soil treated with field-realistic concentrations of 1 of 2 diamide #insecticides (chlorantraniliprole or cyantraniliprole) and/or 1 of 2 #fungicides (boscalid or difenoconazole), either alone or in combination, during a 30-week #hibernation period

How does exposure to commonly encountered #pesticide residues in soil during hibernation affect #bumblebee queens? Find out more about size-dependent lethal and sublethal effects of pesticide exposure in soil from Dr. Sabrina Rondeau and my new-ish paper: doi.org/10.1016/j.sc...

This apparent preference for pesticide-contaminated soils increases the likelihood of exposure to and potential hazard from #pesticide residues in soil for #bumblebee queens during hibernation, a critical and highly vulnerable period of their annual life cycle

#Bumblebee queens consistently avoided hibernating in pesticide-free soil at both contamination levels, while showing no avoidance for any pesticide-treated soil types (lower = field-realistic levels, and higher were 10x max. concentrations detected in soil: doi.org/10.1016/j.en...)

#Bumblebee queens had access to arrays of 36 crates of soil treated with 1 of 5 different #pesticides & untreated (control) soil. After mating, queens were free to choose and dig into any of these soil crates to undergo hibernation. Later, we excavated soil crates to locate queens

We used 5 of the most commonly encountered #pesticides in agricultural soils (boscalid, chlorantraniliprole, clothianidin, cyantraniliprole, difenoconazole) for testing at 2 contamination levels (lower or higher) based on field-realistic exposure estimates: doi.org/10.1016/j.en...

To work out if #bumblebee queens can detect and avoid pesticide-contaminated soils we performed a multiple-choice preference test in which newly emerged queens were given access to arrays of soil treated with different #pesticides in large mesh-covered enclosures
