Resumo
This research deals with the analysis of the enzymes present in thoracic gland extracts from newly emerged, nurse workers, forager workers, newly emerged males, and mature males of A. mellifera L. (Hymenoptera, Apoidea, Apidae). The enzymes found in larger quantities in the thoracic gland occurred in all classes of workers and are digestive. Acid phosphatase and Naphtol-AS-BI-phosphohydrolase act in protein synthesis, leucine arylamidase hydrolyses proteins and a-glucosidase actuate in the nectar processing into honey. Naphtol-AS-BI-phosphohydrolase was found in larger quantities only in workers, this suggests action in protein synthesis by the thoracic gland, b-galactosidase is in larger amounts in the newly emerged bees (workers and males) this aids in the provision of other substances to be used as an energy source when glucose or sucrose are absent. Differences between enzymatic profiles from workers and males are usually related to their colony tasks, or related to their physiological necessities per individual in specific life stages.
