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.
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 previously suggested protection from microbial attack of ripening nectar by the addition of glucose oxidase by the common honey bee, Apis mellifera L., has been found to occur in 9 other eusocial Hymenoptera from 3 superfamilies. The antibacterial effect results from the accumulation of hydrogen peroxide produced by the...
The hepatotoxic alkaloids known to occur in tansy ragwort (Senecio jacobaea L.) are also present in honey produced from the nectar of this species. These alkaloids, which include senecionine, seneciphvlline, jacoline, jaconine, jacobine, and jacozine, are potentially carcinogenic, mutagenic and teratogenic and may pose health hazards to the human consumer.
An examination of a commercial honey-bee apiary for the Acarcapis species complex revealed the following: queens were essentially free from Acarapis parasitism: colonies were more frequently
infested with A. dorsaiis and A. woodi than A. externus: individual worker-bee hosts were
rarely parasitized by more than one Acarapis species. Observed sex...
As a result of the Chernobyl accident on April 25, 1986. possible radioactive contamination
of honey bees and cheese sampled in several areas of the United States were measured. Of
bees collected in May and June of 1986 in both Oregon and New York, only those from Oregon
showed detectable...
A quantification of the number of adult worker Apis meltifera L. found on
combs of standard sizes at full holding capacity is reported. Estimating the holding capacity
of combs can assist in evaluating honey-bee colonies for pollination capabilities and also for
honey-production potentials
Hornets of the genus Vespa are recognized as efficient and devastating predators of honey bees, especially in tropical and subtropical biomes. Of the four species of honey bees in the genus Apis only A. dorsata Fabr., the giant honey bee, appears free from attack by hornets (Seeley et al. 1982)....
Polyethylene film controlled release packets utilizing ethylene dibromide (EDB) and pdichlorobenzene
(PDB) were designed and tested against late instar larvae of Galleria mellonella
(L.). EDB controlled release packets gave 100% control of larvae in 48 h under
experimental conditions at 26.6° and 32.3°C. PDB controlled release packets gave 13.3 and...
Mating flight records are presented for males (drones) of the Asian dwarf honeybee species
Apis florea. These include observations on longevity, mortality and inclusive flight records for a cohort of
known-aged males. Averages for flight performance show the flights/lifetime to be 15.3 (± 11.8 SD); the
number of flight days,...
