Yameogo L, Traore K, Back C, Hougard JM, Calamari D: Risk assessment of etofenprox (Vectron) on non-target aquatic fauna compared with other pesticides used as Simulium larvicide in a tropical environment. Chemosphere. 2001 Mar;42(8):965-74.
Etofenprox, one of the pseudo-pyrethroids tested, shows a global detachment of non-target insects in 24 h close to that of pyraclofos, an organo-phosphorus compound (27 against 23%).
In laboratory conditions, six times the operational dose which is 0.03 mg l (-1) 10 min, is needed to cause 50% mortality of Caridina sp. (a small shrimps species) and 30 times this same dose for 95% mortality. |
