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

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

Attractiveness and toxicity of two insecticides to Tetragonula laeviceps (Apidae: Meliponinae)
Abstract Stingless bee, Tetragonula laeviceps, plays a primary role in ecosystem services as a pollinator for coffee, cocoa, and pepper. Attacks of insect pests cause low production of several plantation plants. Farmers commonly use synthetic insecticides to control insect pests.

Chemical Composition and Biological Activity of Propolis from Brazilian Meliponinae
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.

Genetic breeding on the bee Melipona scutellaris (Apidae, Meliponinae) [PDF]
A selection of queens of Melipona scutellaris through the most productive colonies were carried out during eight months in an orange honeyflow. Each of the colonies was evaluated by its production, that is, the gross weight production ( pollen, brood, geopropolis and wax of each hive).
