| [relation between the size of the acid gland and the quantity of venom produced in africanized bee, apis mellifera l. (hymenoptera: apidae), in the region of dourados, ms, brazil]. | crosses between african and european honeybees in brazil resulted in a highly defensive hybrid bee. the acid gland is important in the expression of this characteristic, being responsible for venom production. morphological variations in this gland could influence the quantity of venom. glandular morphology was analyzed, along with the quantity of venom produced and the bees' genetic characteristics. the gland and the venom reservoir were removed from workers. the gland was placed on a histologi ... | 2006 | 17348132 |
| [morphologic analysis of the venom gland of apis mellifera l. (hymenoptera: apidae) in populations of mato grosso do sul, brazil]. | in apis mellifera l. the venom gland (also called acid gland) is composed of secretory cells that surround a channel that opens into a reservoir devoid of musculature. this gland can present apical branching. in this study the frequency of branched venom glands in africanized honeybee workers (a. mellifera) from eleven localities in the state of mato grosso do sul was recorded. the relations among the length of the main duct, the length of the duct from the reservoir to the beginning of branchin ... | 2007 | 17607453 |
| pollen analysis reveals plants foraged by africanized honeybees in the southern pantanal, brazil. | the pollen diet of africanized honeybees apis mellifera l. was studied during seven months (october 2006 to april 2007) in a natural forest fragment in the southern pantanal, sub-region of abobral, mato grosso do sul. the analysis of the pollen diet was based on direct observations of the bees visiting flowers as well as through the use of a pollen trap installed in a wild colony in a tree hole in the same forest fragment. the total of 28 species in 15 botanical families were observed as potenti ... | 2011 | 21437482 |
| antioxidant and cytotoxic activity of propolis of plebeia droryana and apis mellifera (hymenoptera, apidae) from the brazilian cerrado biome. | propolis is a complex bioactive mixture produced by bees, known to have different biological activities, especially in countries where there is a rich biodiversity of plant species. the objective of this study was to determine the chemical composition and evaluate the antioxidant and cytotoxic properties of brazilian propolis from the species plebeia droryana and apis mellifera found in mato grosso do sul, brazil. in the ethanolic extracts of p. droryana propolis (exep-p) and a. mellifera (exep- ... | 2017 | 28898258 |
