Guardians of the flora: the peril of pesticides in Caatinga to native bees beha...
Abreu , Isabel Oliveira; Teixeira, Cláudia; dos Santos, Jefferson Alves; Rebouças, Jaíne Santos; Caldas, Maiara Janine MachadoBackground: The impact of pesticides on bees and the devastating effects of pesticides evokes a sense of urgency and concern among scientists and environmentalists alike [1]. Once hailed as agricultural saviours, pesticides now threaten bee populations globally. Neonicotinoids and organophosphates harm bee behaviour, hindering navigation, foraging, and reproduction. Sublethal doses further weaken bees, impactin...
Antioxidants activity and physicochemical properties of honey from social bees ...
Silva, Irana Paim; Caldas, Maiara Janine Machado; Machado, Cerilene Santiago; Nascimento, Andreia Santos do; Lordêlo, Maurício SantanaThis study compared the nutraceutical potential of Apis mellifera and Melipona quadrifasciata anthidioides honeys from the semiarid region of Bahia, Brazil, using microbiological, melissopalynological, and physicochemical techniques. Total phenols and flavonoids and the antioxidant activity were also determined. All samples had good microbiological quality and safety with an absence of coliforms, Escherichia co...
Pollen spectrum of honey of Apis mellifera L. and stingless bees (Hymenoptera: ...
Santos, Polyana Carneiro dos; Nascimento, Andreia Santos do; Sodré, Geni da Silva; Carvalho, Carlos Alfredo Lopes de; Alves, Rogério Marcos de OliveiraPollen in honey reflects its botanical origin and melissopalynology is used to identify origin, type, and quantities of pollen grains of the botanical species visited by bees. This study aimed to identify the pollen spectrum of honeys from Apis mellifera and stingless bees produced in the semi-arid region of Bahia, Brazil. We analysed 78 honey samples, which were submitted to the acetolysis process for identifi...
