Does beekeeping reduce genetic variability in Melipona scutellaris (Apidae, Meliponini)?
Many factors have contributed to reductions in wild populations of stingless bees, such as: deforestation, displacement and destruction of nests by honey gatherers, as well as use of insecticides and other agrochemicals. All of these can potentially affect the populational structure of native species. We analyzed genetic variability and populational structure of Melipona scutellaris, based on f...
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...
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 کاملDifferentially displayed expressed sequence tags in Melipona scutellaris (Hymenoptera, Apidae, Meliponini) development.
We have compared gene expression, using the Differential Display Reverse Transcriptase-Polymerase Chain Reaction (DDRT-PCR) technique, by means of mRNA profile in Melipona scutellaris during ontogenetic postembryonic development, in adult worker, and in both Natural and Juvenile Hormone III-induced adult queen. Six, out of the nine ESTs described here, presented differentially expressed in the ...
متن کاملInsights into the Melipona scutellaris (Hymenoptera, Apidae, Meliponini) fat body transcriptome
The insect fat body is a multifunctional organ analogous to the vertebrate liver. The fat body is involved in the metabolism of juvenile hormone, regulation of environmental stress, production of immunity regulator-like proteins in cells and protein storage. However, very little is known about the molecular mechanisms involved in fat body physiology in stingless bees. In this study, we analyzed...
