Visual constraints in foraging bumblebees: Flower size and color affect search time and flight behavior
TLDR
Evaluating the flight behavior of bumblebees searching for artificial flowers shows that foraging speed may not be limited only by factors such as prey density, flight energetics, and scramble competition, and that understanding the behavioral ecology of foraging can substantially gain from knowledge about mechanisms of visual information processing.

RFID Tracking of Sublethal Effects of Two Neonicotinoid Insecticides on the Foraging Behavior of Apis mellifera
TLDR
This study demonstrates that the RFID-method is an effective way to record short-term alterations in foraging activity after insecticides have been administered once, orally, to individual bees.

Synaptic organization in the adult honey bee brain is influenced by brood-temperature control during pupal development
TLDR
It is concluded that thermoregulatory control of brood rearing can generate area- and modality-specific effects on synaptic neuropils in the adult brain, and proposed that resulting differences in the synaptic circuitry may affect neuronal plasticity and may underlie temperature-mediated effects on multimodal communication and learning.

Behavioral performance in adult honey bees is influenced by the temperature experienced during their pupal development
TLDR
It is proposed that the temperature at which pupae are raised will influence their behavioral performance as adults and may determine the tasks they carry out best inside and outside the hive.

Adult honeybees (Apis mellifera L.) abandon hemocytic, but not phenoloxidase-based immunity.

Hot bees in empty broodnest cells: heating from within
TLDR
It is found that the heating bees can be distinguished from the resting bees not only by their higher body temperatures but also by the continuous, rapid respiratory movements of their abdomens.

Worker piping in honey bee swarms and its role in preparing for liftoff
TLDR
The time-course of worker piping matches that of swarm warming; both start at a low level, about an hour before liftoff, and both build to a climax at lif toff.

Size determines antennal sensitivity and behavioral threshold to odors in bumblebee workers
TLDR
The results clearly show that, in the social bumblebees, variation in olfactory sensilla number due to size differences among workers strongly affects individual odor sensitivity, and speculate that superior odor sensitivity of large workers has favored size-related division of labor in bumblebee colonies.

Immune-related proteins induced in the hemolymph after aseptic and septic injury differ in honey bee worker larvae and adults.
TLDR
Evidence is presented that in vitro reared honey bee larvae respond with a prominent humoral reaction to aseptic and septic injury as documented by the transient synthesis of the three antimicrobial peptides (AMPs) hymenoptaecin, defensin1, and abaecin.
