This was documented in assays where the coprophagous larvae and adults of N. cornicina were exposed to dung collected from calves dosed with topical preparations of deltamethrin, flumethrin, cyfluthrin, and alpha-cypermethrin. Larval mortality was significantly increased in dung collected up to at least seven days… CONTINUE READING
