Article Synopsis
- * Thiamethoxam targets the nervous system of insects, leading to severe health issues, and its harmful effects were assessed in the stingless bee Partamona helleri, specifically looking at chronic exposure to low concentrations found in pollen.
- * The study found that thiamethoxam exposure caused significant damage to the midgut, increased oxidative stress, and negatively impacted the behavior of P. helleri, affecting their overall health and ability to function as pollinators.

The widespread use of pesticides in agriculture has been linked to declines in bee populations worldwide. Imidacloprid is a widely used systemic insecticide that can be found in the pollen and nectar of plants and has the potential to negatively impact the development of bee larvae. We investigated the effects of oral exposure to a realistic field concentration (20.

However, its populations can be reduced by the pyrethroid insecticide lambda-cyhalothrin. This compound may cross the intestinal barrier and circulate through the hemolymph, affecting various non-target bee organs.
