🚨🐝 FUN SCIENCE ALERT! 🐝🚨Hibernating bumblebee queens can survive up to a WEEK underwater!! The discovery stems from an oversight leading to these tough little queens defying the odds, emerging alive after an accidental underwater stint! 🌊🐝 #FunScience #BumblebeeSuperheroes

Can #bumblebee queens endure periods of inundation while overwintering underground? New Biology Letters paper from Dr. @SabRondeau suggests that hibernating queens can survive up to 1 week submerged under water: doi.org/10.1098/rsbl.2… #OpenAccess #Pollinators @RSocPublishing

L’automne est arrivé, les feuilles sont colorées et les citrouilles pollinisées par les #abeilles de la courge sont maintenant bien mûres dans les champs. En cette période de récolte, rappelons-nous de remercier les 🐝 pour leur importante contribution! 🎃🍂🍎

Septembre est une période cruciale pour les #pollinisateurs. Les fleurs, comme la verge d'or, sont abondantes, permettant aux reines #bourdons d'accumuler les réserves de graisses dont elles auront besoin pour passer l'hiver. 🐝🌺🍂

🗞️ "Understanding and comparing relative pesticide risk among North American wild bees from their association with agriculture" ⤵️ @uofg @uOttawa With #NSERCsupport.
Sabrina Rondeau, PhD@SabRondeau

Recently published in @SciTotEnv w/@Squash_Bee : sciencedirect.com/science/articl… This study is an attempt at characterizing and comparing #pesticide risk among North American wild #bee species from their association with agriculture. 🐝👩‍🌾🌽🚜🍎 🧵(1/4)

(4/4) Most species facing the highest potential risk are ground-nesters. This suggests that species commonly proposed as models for #pesticide #RiskAssessments may not accurately represent risk for those bee species facing the highest potential risk in agricultural contexts.

(3/4) A sublist of 60 wild 🐝 species falling within the 90th percentile for Bee-Crop Risk Scores provides a representation of the species experiencing the highest potential pesticide risk from associating with crops across North America. ⚠️🐝🌽

Tandis que la plupart des 🐝 sont bien actives durant l’été à collecter du pollen pour nourrir leurs larves, certaines ne suivent pas cette routine! Les 🐝 coucous (#cleptoparasites) pondent leurs œufs dans d'autres nids, laissant leurs larves être nourries par d'autres espèces.

(5/5) Our results show that effects of pesticide exposure depend on intrinsic traits of bumblebee queen physiology and challenge our understanding of how bees respond to pesticides under environmentally realistic exposure scenarios.

(4/5) Exposure to cyantraniliprole led to lethal and sublethal post-hibernation effects that were dependent on queen size, with larger queens showing higher mortality rates, delayed emergence of their first brood, and producing smaller workers.
