Apis mellifera L. presents threww different types of abdominal glands: (i) unicelular tergal glands, represented by: a) the Koschenikow glands, situated in the VIII abdominal tergum of workers and queens; b) the Nassanoff glands or scent glands located in the VII tergum of workers; c) the Renner and Baumann glands located in the III, IV and V terga of the queens; (ii) epithelial glands, represented by wax glands of worker bees; (iii) glands associated to the sting: a) acid; b) basic glands, occurring in both castes. The study of the developmental cycle of the abdominal glands was done by means of morfometric tecniques which consisted in direct measurements of the cells and their nuclei diameters and further calculation of their respective areas: The occurrence and morphometric studies showed correlations between the developmental cycle and the glands function and bees behavior.
