The cuticle surface of insects displays functions in communication, such as recognition. It is known that oenocytes are responsible for the origin of the compounds found in the epicuticle. Secretion of exocrine glands might ... -
Exposure of larvae to thiamethoxam affects the survival and physiology of the honey bee at post-embryonic stages
Tavares, Daiana Antonia; ; ; ; ; Malaspina, Osmar ; ; ; (Environmental Pollution, 2017) [Artigo]
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 ... -
