| Morphological, chemical and developmental aspects of the Dufour gland in some eusocial bees (Hymenoptera, Apidae): a review. The present revision focused on the more recent data about the Dufour gland in some eusocial bees, taking in account general aspects of its morphology, secretion chemical nature, bio-synthetic pathway and development. Many functions have been attributed to this gland in eusocial bees, but none are convincing. With the new data about this gland, not only the secretion chemical pathway of the Dufour gland may be reasonable understood, as its function in some eusocial bees, especially Apis mellifera Linné, 1758, which has been extensively studied in the last years. |

| ABSTRACT Exocrine glands play important role in social organization of insects, such as caste and inter-caste differentiation. Due their functional and structural plasticity, morphological studies on such glands contribute to better understanding the biology of social bees. Therefore, the aim of the study was to characterize the sequence of the post-embryonic development of intramandibular glands of Friesella schrottkyi (Friese, 1900) (Hymenoptera: Apidae) workers using histological and histochemical analyses. The mandibles of pupae at different developmental stages and newly emerged adults were analyzed. The intramandibular glands of F. schrottkyi presented two types: class I glands, in the mandible epidermis and class III glands, inside the mandible... |

| The Dufour gland is found closely associated with the sting apparatus of all hymenopteran females, playing multiple roles among bees. In Apis mellifera Linnaeus, 1758 the gland is connected to the dorsal vaginal wall and, in queens, it produces egg-marking pheromones. In workers the function of this gland is unknown, except by its capacity to mimic the queen secretion in egg-laying workers. In an attempt to understand the development and to substantiate the present knowledge about the Dufour gland in A. mellifera, a morphometric study of the gland between and within the female castes was made. Glands of workers and queens with different ages and life stages were dissected and measured with an ocular micrometer adapted to a stereoscope. The results showed... |
