Popis: | SUMMARYAn evaluation of honey bee (Apis mellifera) defensive behaviour, worker morphometrics and worker brood cell size was conducted in an apiary in an area undergoing Africanization with the aim of documenting the rate of change of these traits across generations, and their reliability to accurately identify colonies. Ten European and 10 Africanized parental colonies (generation P; groups 1and 2, respectively) were selected in accordance with their morphometrics and subjective evaluation of their behaviour in the field. These colonies were tested for three traits of defensiveness using a standard protocol. Colonies' worker morphometrics and worker cell dimensions were also measured. After the P generation colonies were tested, queens were removed and colonies were allowed to requeen themselves. The virgin queens of the following generation (F1) were allowed to mate freely and, six months later, colonies were again tested. This procedure of mother-daughter queen replacement and testing of colonies was pe... |
