Honey production by Africanized and European honey bees in Costa Rica

Abstract

Seventeen colonies of bees were used in a test of honey production in a coffee plantation in Costa Rica. The identities of the colonies were not known at the beginning of the experiment. Behavioral identifications were made in the field as to whether a colony was ’strongly Africanized’, ’strongly European’ or ’intermediate’. The distance spanned by 10 linear worker cells was also measured in the field. Morphometric analyses, conducted independenUy, identified colonies as probably Africanized or probably European. Although the ’intermediate’ category tended to produce more honey, there was no significant difference in honey production between bee types, whether sorted by behavior or morphometrics. There was no significant correlation between initial colony weight or brood area and total amount of honey produced. Appropriate uses of behavioral and morphometric identifications are discussed.
