Ethanol-Induced Effects on Sting Extension Response and Punishment Learning in the Western Honey Bee (Apis mellifera) Acute ethanol administration is associated with sedation and analgesia as well as behavioral disinhibition and memory loss but the mechanisms underlying these effects remain to...

Chronic Exposure of Imidacloprid and Clothianidin Reduce Queen Survival, Foraging, and Nectar Storing in Colonies of Bombus impatiens In an 11-week greenhouse study, caged queenright colonies of Bombus impatiens Cresson, were fed treatments of 0 (0 ppb actual residue I, imidacloprid; C...

Changes in Learning and Foraging Behaviour within Developing Bumble Bee (Bombus terrestris) Colonies Organisation in eusocial insect colonies emerges from the decisions and actions of its individual members. In turn, these decisions and actions are influenced by the individual's behaviour (or...

How Does Pollen Chemistry Impact Development and Feeding Behaviour of Polylectic Bees? Larvae and imagos of bees rely exclusively on floral rewards as a food source but host-plant range can vary greatly among bee species. While oligolectic species forage on pollen from a single family of host...

Honey Bees Avoid Nectar Colonized by Three Bacterial Species, But Not by a Yeast Species, Isolated from the Bee Gut The gut microflora of the honey bee, Apis mellifera, is receiving increasing attention as a potential determinant of the bees’ health and their efficacy as pollinators. Studies...

Development of a New Method to Track Multiple Honey Bees with Complex Behaviors on a Flat Laboratory Arena A computer program that tracks animal behavior, thereby revealing various features and mechanisms of social animals, is a powerful tool in ethological research. Because honeybee colonies...

Physiological and Behavioral Changes in Honey Bees (Apis mellifera) Induced by Nosema ceranae Infection Infection with the microsporidian, Nosema apis, has been shown to advance behavioral maturation in workers. Nosema ceranae had a negative effect on lifespan (z = 3.97, n = 363, p<0.0001...

Fine-Scale Linkage Mapping Reveals a Small Set of Candidate Genes Influencing Honey Bee Grooming Behavior in Response to Varroa Mites To search for genes influencing this trait, we used an Illumina Bead Station genotyping array to determine the genotypes of several hundred worker bees at over a...

The Trail Less Traveled: Individual Decision-Making and Its Effect on Group Behavior Strong symmetry breaking may be a mechanism . . . to competitively exclude other species from resources, . . . However, for species that are lower in the dominance hierarchy and that rely on rapid discovery of...

Social Reinforcement Delays in Free-Flying Honey Bees (Apis mellifera L.) Due to the cyclical rhythm of honey bee foraging behaviors, a post-reinforcement delay at a foraging location would in turn delay a variety of social behaviors in the hive such as unloading behaviors. Free-flying honey...

No Trade-Off between Learning Speed and Associative Flexibility in Bumblebees: A Reversal Learning Test with Multiple Colonies Differences in learning performance and cognitive (behavioral) flexibility could reflect more general differences in colony learning ability. Or to “dumb it down†–...

Observation and guesses. We have a single box hive with an empty box above to protect the feeding jar. Last night we noticed a behavior I have been unable to figure out. At each entrance to the hive about 10 worker bees are hanging out. Figuring it might be too hot or crowded Ruth and I...
