Abstract

A test was made to determine whether the ability manifested by individual Apis mellifera worker bees to rid themselves of the mite Varroa jacobsoni is transmitted to subsequent generations. Eight Africanized bee colonies were selected, four of them were determined to have low ability and four had high ability to rid themselves of the mites. Sisterx brother crosses were performed by instrumental insemination to generate the F1 generation. In the parental generation the mean percentageof artificially infested workers who rid themselves of the mite was 17.5% in the group of colonies with low ability and 57.5% in the group of colonies with high ability. In the F1 generation, 18% of the bees from low ability colonies rid themselves of the mite as opposed to 59.5% of the bees from high ability colonies. We conclude therefore that this behavior is inheritable.
