Method for maintaining adult solitary bee Centris analis under laboratory conditions
(2022-03-01)
Although solitary bees represent at least 70% of bee species, most ecotoxicological studies on bees focus on social species and there are only a few species of solitary bees. One of the challenges in developing toxicological ...
Toxicity of barbatimao to Apis mellifera and Scaptotrigona postica, under laboratory conditions
(Int Bee Research Assoc, 2003-01-01)
Two species of plants commonly known as barbatim (a) over tildeo occur in Brazil, Stryphnodendron adstringens (Fabaceae) (true barbatim (a) over tildeo) and Dimorphandra mollis (Caesalpiniaceae) (false barbatim (a) over ...
Can the exposure of Apis mellifera (Hymenoptera, Apiadae) larvae to a field concentration of thiamethoxam affect newly emerged bees?
(2017-01-01)
The use of insecticides on crops can affect non-target insects, such as bees. In addition to the adult bees, larvae can be exposed to the insecticide through contaminated floral resources. Therefore, this study aimed to ...

Toxicity of barbatimão to Apis mellifera and Scaptotrigona postica, under laboratory conditions
(2003-01-01)
Two species of plants commonly known as barbatimão occur in Brazil, Stryphnodendron adstringens (Fabaceae) (true barbatimão) and Dimorphandra mollis (Caesalpiniaceae) (false barbatimão). These two species have a similar ...
A Brazilian Social Bee Must Cultivate Fungus To Survive
(CELL PRESSCAMBRIDGE, 2015)
FIPRONIL promotes motor and behavioral changes in honey bees (APIS Mellifera) and affects the development of colonies exposed to sublethal doses
(Wiley-Blackwell, 2015-05-01)
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 ...
Exposure of larvae to thiamethoxam affects the survival and physiology of the honey bee at post-embryonic stages
(2017-01-01)
Under laboratory conditions, the effects of thiamethoxam were investigated in larvae, pupae and emerging honey bees after exposure at larval stages with different concentrations in the food (0.00001 ng/μL, 0.001 ng/μL and ...
Fungicide pyraclostrobin affects midgut morphophysiology and reduces survival of Brazilian native stingless bee Melipona scutellaris
(2020-12-15)
Native stingless bees are key pollinators of native flora and important for many crops. However, the loss of natural fragments and exposure to pesticides can hinder the development of colonies and represent a high risk for ...
