“…1), and is believed to be a homologue of the colleterial gland of other insects, i.e. an accessory reproductive gland (Carlet 1884, Maschwitz and Kloft 1971, Hermann 1969, Hermann and Blum 1967a, 1967b, Abdalla and Cruz-Landim 2001. The sting apparatus in Hymenoptera is ectodermal in origin and arises as a modification of the female reproductive system, as evidenced from developmental ontogeny.…”

“…Branch lengths do not have any significance. 1967a, 1967b, Abdalla and Cruz-Landim 2001, the ancestral function of the gland could be similar to roles performed by the colleterial gland in other insects, like forming a protective casing (ootheca) over the eggs, or producing cementing material for attaching eggs to the substrate (Brunet et al 1952). Colleterial glands in a moth (Lepidoptera, a sister clade of Hymenoptera) have been found to function in attaching eggs to leaves of plants (Chaudhuri and Sinha 1994).…”

The poison gland and Dufour's gland are the two glands associated with the sting apparatus in female Apocrita (Hymenoptera). While the poison gland usually functions as an integral part of the venom delivery system, the Dufour's gland has been found to differ in its function in various hymenopteran groups. Like all exocrine glands, the function of the Dufour's gland is to secrete chemicals, but the nature and function of the secretions varies in different taxa. Functions of the Dufour's gland secretions range from serving as a component of material used in nest building, larval food, and pheromones involved in communicative functions that are important for both solitary and social species. This review summarizes the different functions reported for the Dufour's gland in hymenopterans, illustrating how the Dufour's gland secretions can be adapted to give rise to various functions in response to different challenges posed by the ways of life followed by different taxa. Aspects of development, structure, chemistry and the evolution of different functions are also touched upon briefly.

“…Thus, the results suggest, that the insemination process or fluid volume is responsible for stimulating these early post-mating changes in honeybee queens. In all aculeate hymenopteran females the poison gland and the Dufour gland is associated with the sting apparatus (Abdalla and Cruz-Landim, 2001). Secretion from the Dufour gland is caste-regulated.…”

An important area of physiology of the honeybee (Apis mellifera) is chemical communication between individuals and castes in the swarm, which maintains its integrity and function. The highly complex social organization of honeybees is mediated through pheromones. Releaser pheromones cause rapid changes in the behaviour of the recipient, while primer pheromones have relatively slow and long-term effects on the physiology and behaviour of the recipient. Queen retinue pheromone (QRP) is a blend of the nine compounds (9-oxo-(E)-2-decenoic acid, (R)-and (S)-9-hydroxy-(E)-2-decenoic acid, methyl p-hydroxybenzoate, 4-hydroxy-3-methyoxyphenylethanol, methyl oleate, coniferyl alcohol, palmityl alcohol, and linolenic acid) and acts as a releaser pheromone by attracting worker bees to the queen. QRP also acts as a primer pheromone by physiologically inhibiting the ovary development of worker bees. An essential component of QRP, 9-oxo-(E)-2-decenoic acid, acts as a long-distance sex pheromone. Defensive behaviour of honeybees is induced and modulated by alarm pheromones. The essential alarm pheromone component is isopentyl acetate (IPA). The unsaturated derivative of IPA, 3-methyl-2-buten-1-yl acetate, was found in colonies of Africanized honeybees. The Nasanov gland of worker bees produces a pheromone (a blend of nerol, geraniol, (E)-and (Z)-citral, nerolic acid, geranic acid and (E,E)-farnesol) that acts as an attracting signal. This pheromone is used for aggregation (during swarming). Adult worker bees also produce a substance, ethyl oleate, that has a priming effect. Ethyl oleate is produced by adult forager bees and acts as a chemical inhibitory factor to delay age at onset of foraging (the presence of older worker bees causes a delayed onset of foraging in younger individuals). Chemical cues on the surface of larvae called a brood pheromone (ethyl and methyl esters of palmitic, linoleic, linolenic, stearic, and oleic acids, E-β-ocimene) are important in the communication between brood and worker bees. This pheromone modulates the feeding behaviour of worker bees, inhibits the activation of the worker ovary, induces worker bees to cap brood cells, increases the activity of the hypopharyngeal glands of nurse bees and modulates the behavioural maturation of worker bees.

“…Já nas abelhas solitárias que constroem ninhos aéreos, a secreção da glândula funciona como elemento aglutinador para a construção do ninho. Também nas abelhas solitárias e quasi-sociais a secreção serve para marcar a entrada do ninho, deixar trilhas de cheiro e também como feromônio de atração sexual (Hefetz 1987, Abdalla & Cruz-Landim 2001c.…”

Neotropical Entomology 34(1): 047-057 (2005) Dufour Gland Occurence, Morphology and Ultrastructure in Scaptogrigona postica Latreille (Hymenoptera: Apidae)ABSTRACT -The Dufour gland is an accessory gland of the bee reproductive female apparatus. In neotropical stingless bees, this gland has been poorly investigated, concerning to developmental, morphological or biochemical characteristics. In order to collaborate with the knowledge of the Dufour gland in stingless bees, a study of its occurrence, morphology and development was performed in Scapatotrigona postica Latreille. The results showed that this gland is absent in workers, although it occurs in workers of many stingless bee species. The glandular cells seem to be very active in virgin queens, presenting a well developed tubular network of smooth endoplasmic reticulum, secretion granules and some polyribosomes in the glandular cell cytoplasm, besides larger nuclei than in physogastric queens. In physogastric queen glands there are two types of cells, both of them apparently not synthetically active. Nevertheless, the physogastric queen glands are clearly able to absorb substances from the haemolymph, probably lipids that do not cross the cells, but pass through the intercellular cell spaces and cuticle, and are released directly to the gland lumen. The very developed double-layered gland basal lamina may actuate in the process of substances uptaking. The secretion, and consequently its function, can be different in these two queen types.KEY WORDS: Exocrine gland, alkaline gland, meliponine RESUMO -A glândula de Dufour é uma glândula acessória do aparelho reprodutivo feminino das abelhas. Nas abelhas neotropicais sem ferrão, tem sido pouca estudada sob todos os aspectos: morfológico, ontogenético e bioquímico. Na tentativa de colaborar com o conhecimento dessa glândula em abelhas sem ferrão, foi realizado um estudo da sua ocorrência, morfologia e desenvolvimento em Scaptotrigona postica Latreille. Os resultados mostraram que ela se encontra ausente nas operárias, como ocorre em muitas outras espécies desse grupo. Nas rainhas, as células glandulares parecem mais ativas nas virgens, possuindo uma desenvolvida rede de retículo endoplasmático liso tubular, grânulos de secreção e polirribossomos dispersos no citoplasma, além de apresentarem núcleos maiores do que os das células glandulares das fisogástricas. Nas rainhas fisogástricas há dois tipos de células glandulares, ambas aparentemente inativas sinteticamente. As glândulas das rainhas fisogástricas são claramente capazes de captar substâncias da hemolinfa, provavelmente lipídios, que não penetram nas células, mas passam pelos espaços intercelulares e, através da cutícula, chegam diretamente à luz da glândula. A bem desenvolvida dupla camada de lâmina basal ao redor da glândula pode atuar no processo de captação de substâncias da hemolinfa. A secreção, e conseqüentemente sua função, pode ser diferente nas duas classes de rainhas.PALAVRAS-CHAVE: Glândula exócrina, glândula básica, meliponíneo Nas abelhas, d...
