Evaluates the impact of thiamethoxam on bee larvae, suggesting heightened sensitivity compared to adult stages.

The aim is to assess the toxicity of thiamethoxam on the larvae of two neotropical bee species using innovative technologies.
Evaluated two species of stingless bees: Melipona scutellaris and Scaptotrigona postica.
Exposed larvae to thiamethoxam at a realistic field dose and two dilutions.
Utilized standardized in vitro protocols alongside patented biomimetic technologies.
Thiamethoxam exposure caused significant mortality in larvae, with over 98% in M. scutellaris at RD/10.
Surviving larvae of M. scutellaris showed developmental issues such as body malformation and reduced size.
S. postica larvae experienced accelerated fungal growth and 100% mortality across all doses tested.

Dorigo et al. (2026) studied this question.
