Africanized honey bee |
Apis mellifera scutellata |
Entomologist David Gilley is part of the team investigating the usurpation of European honey bee colonies by swarms of Africanized honey bees. Because queenless colonies are particularly susceptible to usurpation, the team maintains a group of queenless colonies to lure usurpation swarms into their apiary to be studied. Gilley is shown here requeening one of these "bait colonies." |

honey bee |
Apis mellifera |
For centuries, beekeeping has been a traditional part of Mexican agriculture and a reliable source of income in rural areas. Scientists in the United States have closely followed the arrival of Africanized honey bees and two species of parasitic mites that have created hive management problems and reduced honey production. |
