The defensive behaviour of the cyprian honeybee apis melifera cypria against the oriental hornet vespa orientalis
Abstract
In the present work, several characteristics of the Cyprian honeybee Apis mellifera cypria were examined, with particular emphasis on its defensive behaviour during natural or simulated attacks by its main enemy, the oriental hornet. Firstly, genetic analyses using mitochondrial and microsatellite DNA were performed and showed that in a large part of the island, the Cyprus honeybee population is genetically homogeneous. Regarding the growth of colonies over the year, the maximum growth was observed in May and the minimum in August, and this characteristic pattern differs from that of other subspecies. Next, the defensive behaviour of individual colonies against hornets, the way honeybees kill invading hornets and the sound produced by defending workers, were investigated in detail. Analysis of data collected, showed two different patens of defensive behaviour by individual colonies. When attacking hornets approached the hive, defending workers in certain colonies avoided confrontation ...
