Chemical Composition of the Dufour Gland Secretion in Queens of Melipona bicolor (Hymenoptera, Meliponini)
نویسندگان
چکیده
Utilizando cromatografia gasosa acoplada à espectrometria de massa, descrevemos as diferenças na composição química da secreção da glândula de Dufour de rainhas virgens e fisogástricas de Melipona bicolor. A secreção da glândula de rainhas virgens consiste de hidrocarbonetos, enquanto a das rainhas fisogástricas contém, além de hidrocarbonetos, uma variedade de outros compostos, tais como ésteres isobutíricos e acéticos. Tais diferenças devem indicar o estado de fecundidade da rainha e os compostos oxigenados da secreção das fisogástricas podem ajudar aumentar sua atratividade.

Comparative study of the cuticular hydrocarbon composition of Melipona bicolor Lepeletier, 1836 (Hymenoptera, Meliponini) workers and queens.
In social insects, cuticular hydrocarbons are involved in species, kin, caste and nestmate recognition. Gas chromatography and mass spectrometry were used to compare the cuticular hydrocarbon composition of workers, males and queens of Melipona bicolor. The cuticular hydrocarbon composition of this species was found to consist mainly of C23, C25:1, C25, C27:1, C27, C29:1 and C29, which are alre...
متن کاملPollen foraging in colonies of Melipona bicolor (Apidae, Meliponini): effects of season, colony size and queen number.
We evaluated the ratio between the number of pollen foragers and the total number of bees entering colonies of Melipona bicolor, a facultative polygynous species of stingless bees. The variables considered in our analysis were: seasonality, colony size and the number of physogastric queens in each colony. The pollen forager ratios varied significantly between seasons; the ratio was higher in wi...
متن کاملUltrastructure of the Intramandibular Gland of Workers and Queens of the Stingless Bee, Melipona quadrifasciata
The intramandibular glands of workers and queens of Melipona quadrifasciata Lepeletier (Hymenoptera: Apidae), at different ages and from different functional groups, were studied using light and transmission electron microscopy. The results demonstrated that these glands are composed of two types of secretory structures: 1.A hypertrophied epidermis on the dorsal side of the mandible that is an ...
متن کاملPrediction of social structure and genetic relatedness in colonies of the facultative polygynous stingless bee Melipona bicolor (Hymenoptera, Apidae)
Stingless bee colonies typically consist of one single-mated mother queen and her worker offspring. The stingless bee Melipona bicolor (Hymenoptera: Apidae) shows facultative polygyny, which makes this species particularly suitable for testing theoretical expectations concerning social behavior. In this study, we investigated the social structure and genetic relatedness among workers from eight...
متن کاملAnalysis of the intercaste transcriptional profile of Melipona scutellaris Latreille, 1811 (Hymenoptera, Apidae, Meliponini) by mRNA differential display.
In colonies of Melipona scutellaris Latreille, 1811 workers can be found with four ganglion nerve cells, a morphological characteristic of the queen. It is hypothesized that these workers, called intercastes, or phenocopies, are phenotypically-like workers, but genotypically identical to queens due to this specific trait. Workers with the same number of ganglion as queens seem to be intercastes...
