چکیده

The aim of the present study was analyze, by histological and morphometrical studies, mandibular glands of Melipona bicolor queens collected from monogynic and polygynic colonies and compare their level of development. The results showed that the glands ofphysogastric queens from monogynic colony present a higher level of activity in relation to the queens of polygynic colonies; this is explained by the fact that just a unique queen controls the monogynic colony. In the polygynic colonies, the queens may divide such control to each other.

Prediction 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...

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...

Pollen 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...

Evidences that genetically determined melipona queens can become workers.

IHERING (1903) suggested that caste determination in Melipona (Hymenoptera Apidae) was not phenotypic but was possibly determined by some mechanism before the egg was laid. On the basis of observations by many authors, we can say that in all genera of social Apidae, except Melipona, caste determination is controlled by quantity or quality of food or both. KERR (1946) found in four colonies of M...

Queen Execution and Caste Conflict in the Stingless Bee Melipona beecheii

Caste conflict theory predicts that worker-destined individuals in insect colonies may try to develop as queens in order to gain greater direct reproduction. In situations where females can determine their own caste fate ( self-determination ), this is expected to lead to overproduction of queens. Theoretical predictions are supported by patterns of queen production in Melipona stingless bees. ...
