Quantifying exposure of bumblebee (Bombus spp.) queens to pesticide residues when hibernating in agricultural soils

This study quantifies pesticide exposure of hibernating bumblebee queens in agricultural soils, finding high residue levels and multiple pesticide mixtures in orchard soils.

Safeguarding pollinators requires specific habitat prescriptions and substantially more land area than current policy suggests

The paper determines that safeguarding wild bee communities in Canadian landscapes requires 11.6-16.7% land-cover from diverse habitats, which is 1.8-3.6x current policy guidelines.

Neonicotinoid exposure affects foraging, nesting, and reproductive success of ground-nesting solitary bees

This study shows that neonicotinoid exposure reduces nesting, foraging, and reproductive success in ground-nesting bees, while other insecticides have no measurable impact.

Acute oral toxicity and risks of exposure to the neonicotinoid thiamethoxam, and other classes of systemic insecticide, for the Common Eastern Bumblebee (Bombus impatiens)

This study assesses the acute oral toxicity of four systemic insecticides to the Common Eastern Bumblebee and compares risk assessment methods.

Captive-reared migratory monarch butterflies show natural orientation when released in the wild

The paper tests whether captive-reared monarch butterflies can orient naturally in the wild, finding that most do so despite showing disorientation in a flight simulator.

Assessment of risk to hoary squash bees (Peponapis pruinosa) and other ground-nesting bees from systemic insecticides in agricultural soil

This study assesses the risk of systemic insecticide exposure to ground-nesting bees via soil, finding high risk from clothianidin and imidacloprid under chronic exposure and acute exposure for clothianidin.
