Pollination of tomatoes by the stingless bee Melipona quadrifasciata and the honey bee Apis mellifera (Hymenoptera, Apidae).
The pollination effectiveness of the stingless bee Melipona quadrifasciata and the honey bee Apis mellifera was tested in tomato plots. The experiment was conducted in four greenhouses as well as in an external open plot in Ribeirão Preto, SP, Brazil. The tomato plants were exposed to visits by M. quadrifasciata in one greenhouse and to A. mellifera in another; two greenhouses were maintained w...
متن کاملAntimicrobial and antiproliferative activities of stingless bee Melipona scutellaris geopropolis
BACKGROUND Geopropolis is a type of propolis containing resin, wax, and soil, collected by threatened stingless bee species native to tropical countries and used in folk medicine. However, studies concerning the biological activity and chemical composition of geopropolis are scarce. In this study, we evaluated the antimicrobial and antiproliferative activity of the ethanolic extract of geopropo...

متن کاملEffect of food quality, distance and height on thoracic temperature in the stingless bee Melipona panamica.
Stingless bees (Apidae, Meliponini) can recruit nestmates to good food sources. We present the first data showing that recruiting meliponine foragers at feeders and inside nests regulate their thoracic temperature according to net food profitability. Using infrared thermography, we found that Melipona panamica foragers elevated their thoracic temperature at profitable food sources (higher sucro...
متن کاملEffect of amino acid and mycorrhiza inoculation on sweet pepper growth under greenhouse conditions
ABSTRACT- The production of greenhouse sweet pepper is increasing because of the consumer demand for sweet pepper year around. In this study, physiological characteristics of sweet pepper were evaluated in a greenhouse under different levels of arbascular mycorrhizal fungus, Glomus intraradices, (AMF) and various levels of amino acid (AA). Treatments included no AMF as a control (AMF1), 1000 sp...
