An experimental formulation of 9 -oxodec-trans-2-enoic acid, the major component of honey bee (Apis mellifera L.) queen pheromone, was tested for its effect on worker foraging behavior in the pollination of sweet cherries (Prunus avium L. ). The test formulation consisted of a solid beeswax cylinder impregnated with a measured...

Male Apis mellifera L. (drones) accompanying reproductive swarms were analyzed for honey stomach contents to determine if they engorge honey prior to or during swarming. No evidence for engorgement was found. A diurnal feeding rhythm in drones was observed in non swarming colonies.
The mating flight behavior of drone honey bees from swarm clusters is compared to drone mating flight behavior from colony situations. Duration of flight from swarms and colony situations is similar. Swarm drones appear to take as many flights/day but spend less time between flights than colony drones.

A previously undescribed system of differential food
storage in replete forms of the honey ant, Myrmecocystus
mexicanus Wesmael, is reported. Certain repletes store lipid as glycerol and cholesterol esters associated with
sugar solutions containing glucose, fructose, and maltose.
