Social attraction mediates collective foraging decisions in invasive hornets

The paper shows invasive hornets use social attraction to make collective foraging decisions, favoring food sources primed with dead conspecifics or related species.

Male bumblebees adapt foraging to environmental conditions to sustain mate-seeking efforts

This study shows male bumblebees adjust foraging behavior to maintain reproductive efforts despite environmental challenges.

Nutritional responses of bumblebees to thermal stress

This study examines how bumblebees adjust their nutritional choices under different thermal stresses, finding that cold stress prioritizes carbohydrates while heat stress disrupts nutrient balance.

Cognitive decline in aging parasitoid wasps

This study shows that aging in parasitoid wasps leads to cognitive decline, affecting their ability to learn and remember odors associated with oviposition rewards.

Human performance in the Traveling Salesman Problem is influenced by spatial scale

This study shows human performance in solving the Traveling Salesman Problem varies with spatial scale, peaking at intermediate scales where global strategies are used.

Interindividual variability in flower pickiness by foraging bumblebees

This study shows that bumblebees adapt their foraging behavior based on early flower experiences, with some becoming more selective and others less, but all achieving similar sucrose intake rates over time.

Invasive Vespa velutina nigrithorax hornets are more susceptible to entomopathogenic fungus than two other hymenopteran species, the wasp Vespa vulgaris and the bumblebee Bombus terrestris.

This study compares the susceptibility of invasive Vespa velutina nigrithorax hornets to the entomopathogenic fungus Metarhizium robertsii with two non-target species, finding hornets more susceptible.

The influence of bee movements on patterns of pollen transfer between plants: an exploratory model

This paper uses an agent-based model with reinforcement learning to simulate bee foraging and shows how learning improves pollination efficiency and genetic differentiation between plant subpopulations.

Bumblebees locate goals in 3D with absolute height estimation from ventral optic flow

This study investigates how bumblebees estimate height in 3D space using ventral optic flow and local/global cues during foraging.

Trapline foraging by nectar-collecting hornets

This study shows that Japanese yellow hornets develop trapline foraging routes similar to bees and birds, optimizing flower visits over time without always taking the shortest path.

Bumblebees increase their learning flight altitude in dense environments

This study shows bumblebees adjust their flight altitude and orientation in dense environments to navigate and locate their nest more effectively.

Honey bees cannot sense harmful concentrations of metal pollutants in food

This study shows honey bees cannot detect harmful metal concentrations in food, only avoiding very high levels that exceed regulatory thresholds.
