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...
Apis mellifera is a pollinator insect model in pesticide risk assessment tests for bees. However, given the economic and ecological importance of stingless bees such as Melipona scutellaris Neotropical region, well lack studies on effect insecticides these bees, toxicity should be carried out to understand whether affect both species same manner. Thus, present study quantified differential sens...
Many factors have contributed to reductions in wild populations of stingless bees, such as: deforestation, displacement and destruction of nests by honey gatherers, as well as use of insecticides and other agrochemicals. All of these can potentially affect the populational structure of native species. We analyzed genetic variability and populational structure of Melipona scutellaris, based on f...
In this study, samples belonging to Hydrophilidae and Helophoridae families collected from Diyarbakır were evaluated. Samples between May-September 2016 April-October 2017 among plants mosses in shallow parts of various streams, springs, deposits ponds. the study area, 12 taxa (species) 7 genera family 10 1 genus determined.
