Africanized honey bee |
Apis mellifera scutellata |
Closeup of Africanized honey bees (AHBs) surrounding a European queen honey bee (EHB), marked with a pink dot for identification. Since AHBs arrived in Texas in 1990, they've mated with EHBs and spread throughout the Southwest. But rather than commingling, AHBs tend to replace EHBs, partly because EHB queen bees mate disproportionately with African drones. |

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." |
