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 ...
Weakness and collapse of bee colonies in Brazil: are there cases of CCD?
(Empresa Brasil Pesq Agropec, 2016-05-01)
In the last decades, the decline of wild bee populations and the collapse of Apis mellifera colonies have concerned researchers and beekeepers. The objective of this review was to compile some of the most relevant studies ...
Wild bees (Hymenoptera: Apoidea) in an urban botanical garden in Buenos Aires, Argentina
(Taylor & Francis, 2015-11)
We assessed bee diversity and abundance in a botanical garden in the city of Buenos Aires during two consecutive spring–summer periods. Every 15 days, we collected by hand-netting bee specimens seen foraging on flowers ...
Differences in the number of some antennal sensilla of four honey bee (Apis mellifera) types and comparisons with the defensive behaviour
(Int Bee Research Assoc, 1998-01-01)
The number of sensilla coeloconica, ampullacea and campaniformia of flagellomeres 3 to 10 of the antennae of workers of four honey bee types (Italian, Caucasian, African and Africanized) was studied by scanning electron ...
Is the number of antennal plate organs (sensilla placodea) greater in hygienic than in non-hygienic Africanized honey bees?
Hygienic behavior is a desirable trait in honey bees (Apis mellifera L.), as hygienic bees quickly remove diseased brood, intermpting the infectious cycle. Hygienic lines of honey bees appear to be more sensitive to the ...

Differences between the quality of strawberries (Fragaria x ananassa) pollinated by the stingless bees Scaptotrigona aff. depilis and Nannotrigona testaceicornis
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) ...
FIPRONIL promotes motor and behavioral changes in honey bees (APIS Mellifera) and affects the development of colonies exposed to sublethal doses
Bees play a crucial role in pollination and generate honey and other hive products; therefore, their worldwide decline is cause for concern. New broad-spectrum systemic insecticides such as fipronil can harm bees and their ...
