Worker honey bee pheromone regulation of foraging ontogeny

Naturwissenschaften, 2004
The evolution of sociality has configured communication chemicals, called primer pheromones, which play key roles in regulating the organization of social life. Primer pheromones exert relatively slow effects that fundamentally alter developmental, physiological, and neural systems.

Queen Pheromone Blocks Aversive Learning in Young Worker Bees

Science, 2007
Queen mandibular pheromone (QMP) has profound effects on dopamine signaling in the brain of young worker honey bees. As dopamine in insects has been strongly implicated in aversive learning, we examined QMP's impact on associative olfactory learning in bees.

LARVAL REARING BY WORKER HONEY BEES LACKING THEIR MANDIBULAR GLANDS: II. REARING BY LARGER NUMBERS OF WORKER BEES

The Canadian Entomologist, 1979
AbstractFurther experiments were done in an attempt to ascertain the significance of the mandibular glands of nurse bees in female caste differentiation. Groups of 200, 10-day-old nurse bees, with their mandibular glands removed, fed female larvae for 80 h in plastic queen cell cups in the laboratory.

A portable incubator for worker bee brood

Bee World, 2003
The construction and function of a self-warmed, portable incubator for sealed worker honey bee (Apis mellifera) brood is described here. This incubator can be used by both static and migratory beekeepers. The prerequisites of a rational use of a portable incubator in the early to middle spring are cited.

Worker-worker inhibition of honey bee behavioural development independent of queen and brood

Insectes Sociaux, 2004
Foragers inhibit the behavioural development of young adult worker honey bees, delaying the age at onset of foraging. But the similar effect caused by pheromones produced by both the queen and brood raised the possibility that some of the previously attributed forager effects might be due to queen, brood, or both.

Queen Bees, Workers and Drones

2010
Collaborative learning online is increasingly popular and the interaction between learners is documented and discussed, but gender is largely absent from this work. This chapter attempts to remedy this gap by offering a review of a study of undergraduate online collaboration.

BROOD SMELL LIMITS WORKER BEES' LIFE EXPECTANCY

Journal of Experimental Biology, 2009
For a few crucial weeks each spring, bees are the most essential labourers on earth, pollinating many of the world's major fruit crops: their survival through winter is fundamental for agriculture.

Worker Matricide in Social Bees and Wasps

Journal of Theoretical Biology, 1994
Abstract In bumble bees (Bombus) and vespine wasps (Vespa, Vespula, Dolichovespula), workers have regularly been observed to kill their colony's single queen (worker matricide). Workers gain a fitness payoff in worker-produced males from matricide because it removes the queen's inhibition over their reproduction.
