Nesting ecology of stingless bees (Hymenoptera, Meliponina) in urban areas: the importance of afforestation

open access: yesBioscience Journal, 2013
Studies on nesting ecology have proven to be extremely important for stingless bees conservation. This kind of study is scarce in urban landscapes. Our study aimed to analyze the abundance, density, diversity, spatial distribution and nesting habits of ...

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

open access: yesInsectes 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 ...

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

open access: yesJournal 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.

Attractiveness and toxicity of two insecticides to Tetragonula laeviceps (Apidae: Meliponinae)

open access: yesIOP Conference Series: Earth and Environmental Science, 2022
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

open access: yesZeitschrift 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.

Genetic breeding on the bee Melipona scutellaris (Apidae, Meliponinae) [PDF]

open access: yesActa Amazonica, 2006
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).
