Mandibular gland pheromone contents in workers and queens of Apis mellifera adansonii

摘要: Secretions from the mandibular glands of honeybees have been studied extensively, with those queens dominated by ώ-9 fatty acids and ώ-10 dominating non-laying workers. Apis mellifera adansonii (Latreille) is one widely distributed subspecies African honeybees. However, its gland pheromones not analysed previously. Using gas chromatography, we composition in workers A. Nigeria. Qualitatively, similar pheromone profiles to previously reported other We found 9-ODA high amounts precursor 9-hydroxy-2 (E)-decenoic acid (9-HDA) workers, thus showing that they produce queen-like signals under queen-right conditions. also geographic variation morphometric characters these suggesting different morphoclusters ecological climatological regions inhabited m.
