Stingless bees and mass flowering trees in the canopy of Atlantic Forest: a tight relationship
(Sociedade Botânica do Brasil, 2004-01)
This study demonstrates that stingless bees (Apidae, Hymenoptera) amount to approximately 70% of all bees foraging on flowers in the Brazilian Tropical Atlantic Rainforest. They also are the unique bee group concentrated ...
The first record on Brazilian stingless bees published 450 years ago by Hans Staden
(FUNPEC-EDITORA, 2009)
Only a few decades after 1492, when Christopher Columbus arrived on a Caribbean island and Pedro Alvares Cabral claimed Brazil for Portugal in 1500, a German mercenary gave the first description of stingless bees in 1557. ...
Toxicity of imidacloprid to the stingless bee Scaptotrigona postica Latreille, 1807 (Hymenoptera: Apidae)
(Springer, 2015-06-01)
The stingless bee Scaptotrigona postica is an important pollinator of native and cultivated plants in Brazil. Among the factors affecting the survival of these insects is the indiscriminate use of insecticides, including ...
Hygienic behavior of the stingless bee Plebeia remota (Holmberg, 1903) (Apidae, Meliponini)
(FUNPEC-EDITORA, 2009)
We investigated hygienic behavior in 10 colonies of Plebeia remota, using the pin-killed method. After 24 h the bees had removed a mean of 69.6% of the dead brood. After 48 h, the bees had removed a mean of 96.4% of the ...
Differences between the quality of strawberries (Fragaria x ananassa) pollinated by the stingless bees Scaptotrigona aff. depilis and Nannotrigona testaceicornis
(FUNPEC-EDITORA, 2009)
We investigated the success of two stingless bee species in pollinating strawberries in greenhouses. Three greenhouses and one open field area were used; one greenhouse had only strawberry plants (control), another (G1) ...
First record of chemical signals from the queen during the oviposition process in stingless bees
(SPRINGER BASEL AGBASEL, 2013-08-02)
In stingless bees, the cell provisioning and oviposition process consists of several integrated behavioral sequences and several stereotyped queen-worker interactions. This study aims to demonstrate that chemical signals ...
Ultrastructure of digestive cells in stingless bees of various ages (Hymenoptera, Apidae, Meliponinae)
(Faculty Press, 1996-01-01)
The ultrastructure of digestive cells of newly emerged, nurse and forager worker bees is described. Newly emerged bees have the endoplasmic reticulum characteristically in whorls and stacks as well as in parallel arrays ...

(Faculty Press, 1996-01-01)
The ultrastructure of digestive cells of newly emerged, nurse and forager worker bees is described. Newly emerged bees have the endoplasmic reticulum characteristically in whorls and stacks as well as in parallel arrays ...
Ultrastructure of digestive cells in stingless bees of various ages (hymenoptera, apidae, meliponinae)
(1996-12-01)
The ultrastructure of digestive cells of newly emerged, nurse and forager worker bees is described. Newly emerged bees have the endoplasmic reticulum characteristically in whorls and stacks as well as in parallel arrays ...
Nutritive value and apparent digestibility of bee-collected and bee- stored pollen in the stingless bee, Scaptotrigona postica Latr. (Hymenoptera, Apidae, Meliponini)
(Elsevier B.V., 2000-01-01)
In Meliponini bees, pollen is stored inside the hive. We compared the nutritional value and apparent digestibility of bee-collected and bee-stored pollen of Scaptotrigona postica. The results showed no differences in ...
