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...
متن کاملQueens become workers: pesticides alter caste differentiation in bees
Bees are important for the world biodiversity and economy because they provide key pollination services in forests and crops. However, pesticide use in crops has adversely affected (decreased) queen production because of increased mortality among larvae. Here, we demonstrated that in vitro-reared queens of a neotropical social bee species (Plebeia droryana) also showed high larval mortality aft...
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 کاملComparative 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...
