Sulphonamides and American Foul Brood Disease of Bees

Brood care by male bumble bees.

Male Bombus griseocollis (Hymenoptera: Apidae) share in the brood care of nestmates by incubating pupae (usually during the first few days after they emerge as adults). Male posture during incubation of a pupa is identical to that observed for females. Pupae incubated by males were 4 degrees C-6 degrees C above the temperature of unincubated pupae. Although this increase was not as great as tha...

What's Killing American Honey Bees?

many Americans woke up to media reports that something was awry with their honey bees. A signifi cant proportion of American beekeepers were complaining of unusually high rates of colony loss as their bees broke from their overwintering clusters. Loss of some colonies (say 10%) in early spring is normal and occurs every year. In 2007, however, losses were particularly heavy and widespread—beeke...

Diagnosis and control of American foulbrood disease of honey bees in the Netherlands

American foulbrood disease (AFB), caused by the bacterium Paenibacillus larvae, is a disease of the European honey bee (Apis mellifera) and other honey bee species (Apis sp.). It is distributed world wide. Spores of the bacterium can infest larvae of the bees, ultimately leading to the death of the larva or pupa. Although often spores are present in bee colonies, it only sporadically leads to s...
