A methodology to assist in locating drone congregation area using remote sensing technique

The mating of honey bees, Apis mellifera L. occurs in the air at specific locations called drone congregation areas (DCAs). The identification of these areas is important for beekeepers especially breeders of queens to ensure the mating of their virgin queens, and for studies on the mating behaviour of honey bee queens. In this study, remote sensing and geographical information systems were used for the first time to develop a methodology that can assist in locating these DCAs. The methodology included analysing landscape characteristics around the apiary to exclude unsuitable areas as DCAs, and finally to limit the search to a smaller area. An isolated apiary was used to develop the methodology and the actual location of the DCA was confirmed using field observations. The results of this study indicated that remote sensing can assist in locating DCAs.
