Comparative acute toxicity of two phytosanitary molecules, lambda-cyhalothrin and acetamiprid, on Nile Tilapia () juveniles.

This study aimed to compare the toxicity for fish of two active ingredients (lambda-cyhalothrin-20 g L, a pyrethroid, and acetamiprid-15 g L, a neonicotinoid) which are components of a commercial insecticide (Acer 35 EC) used in cotton crop in many West African countries. The juveniles of (4.01 ± 0.

Occurrence of Acetamiprid Residues in Water Reservoirs in the Cotton Basin of Northern Benin.

An Ultra performance liquid chromatography (UPLC) coupled to UV detection method was developed to determine acetamiprid residues in water reservoirs of northern Benin, close to cotton fields. The quantification limit of this method was 0.2 µg L acetamiprid in water, its precision ranged between 8% and 22%, and its trueness between 99% and 117% (for concentrations ranging from 0.
