Diversity and Nesting Substrates of Stingless Bees (Hymenoptera, Meliponina) in a Forest Remnant

Psyche: A Journal of Entomology, 2012
Stingless bees are abundant and diverse key actors in several plant-pollinator networks in the neotropics, but little is known about their natural history and ecology.

Inheritance Pattern of RAPD Markers in Melipona quadrifasciata (Hymenoptera: Apidae, Meliponinae) [PDF]

Journal of Heredity, 2001
Melipona quadrifasciata is an important pollinator agent in several regions of Brazil. Data concerning the genetics of this species are scarce in the literature. In this work we used the random amplified polymorphic DNA (RAPD) technique to determine the degree of polymorphism and the inheritance pattern of these molecular markers in this species.

A case of multiple mating in stingless bees (Meliponinae) [PDF]

Insectes Sociaux, 1998
In several stingless bee species many males aggregate in the vicinity of a nest when a virgin queen is present in the colony and is preparing for the nuptial flight. We report such male assemblage for Tetragonisca angustula. The departure of a virgin queen from the colony and the subsequent mating could be video-recorded, because the queen and the ...

Ginandromorfia em Melipona mondury Smith (Hymenoptera, Apidae, Meliponinae)

SITIENTIBUS série Ciências Biológicas, 2006
Pela primeira vez é descrita a ocorrência de um ginandromorfo de Melipona mondury, coletado juntamente com machos e fêmeas normais. O espécime possui assimetria bilateral, apresentando a metade direita da cabeça com caracteres de macho e a metade esquerda com caracteres de fêmea; o mesossoma apresenta caracteres de macho verificados principalmente pelo

Note on glands present in meliponinae (Hymenoptera, Apidae) bees legs [PDF]

Revista Brasileira de Zoologia, 1998
The present paper reports the presence of glandular structures in legs of some stingless bee species. The glands appear as: the epidermis transformation in a glandular epithelium as in basitarsus, an epithelial sac inside the segment as in the femur of queens or in the last tarsomere, as round glandular cells, scattered or forming groupments.

Genetic Diversity of Melipona mandacaia SMITH 1863 (Hymenoptera, Apidae), an Endemic Bee Species from Brazilian Caatinga, Using ISSR

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
In order to evaluate the genetic diversity and structure of Melipona mandacaia, we analyzed 104 colonies collected in 12 localities in Bahia state, northeastern Brazil, using ISSR‐PCR. A total of 109 bands were obtained with a significant polymorphism of 72.47%.

Genetic variability of behaviorin Melipona quadrifasciata(Hymenoptera: Meliponinae)

Brazilian Journal of Genetics, 1997
Observation colonies containing only young workers from 10 matrix colonies were set up to investigate the genetic aspects involved in task division in Melipona quadrifasciata. Wide variation among origins was observed for all behaviors analyzed, but these differences were significant only for brood cell construction and propolis ...

Chemical Composition and Biological Activity of Propolis from Brazilian Meliponinae

Zeitschrift für Naturforschung C, 2000
Abstract Twenty-one propolis samples produced by 12 different Meliponinae species were analyzed by GC-MS. Several chemical types of stingless bees’ propolis could be grouped, according to the prevailing type of compounds like: “gallic acid”, “diterpenic” and “triterpenic” types.

Investigating Eusociality in Bees while Trusting the Uncertainty

Sociobiology, 2014
Phylogenetic hypotheses and estimates of divergence times have already been used to investigate the evolution of social behavior in all lineages of bees. The interpretation of the number of origins of eusocial behavior and the timing these events depends
