Inhibition of Larval Development of Marine Copepods Acartia tonsa by Neonicotinoids.

ABSTRACT: Neonicotinoids (NEOs) are neurotoxic pesticides widely used in agriculture due to their high effectiveness against pest insects. Despite their widespread use, very little is known about their toxicity towards marine organisms, including sensitive and ecologically relevant taxa such as copepods. Thus, we investigated the toxicity of five widely used NEOs, including acetamiprid (ACE), clothianidin (CLO), imidacloprid (IMI), thiacloprid (THI), and thiamethoxam (TMX), to assess their ability to inhibit the larval development of the copepod Acartia tonsa. The more toxic NEOs were ACE (EC₅₀ = 0.73 μg L^-1), TMX (EC₅₀ = 1.71 μg L^-1) and CLO (EC₅₀ = 1.90 μg L^-1), while the less toxic compound was IMI (EC₅₀ = 8.84 μg
