Abstract

The 6 LC50 for nymphs of Hexagenia rigida exposed to permethrin-contaminated water without sediment was estimated to lie between 0.58 and 2.06 μg/L. No nymphs survived a 6 h exposure to 7.63 μg/L. Laboratory simulated application of 7.3 g/ha permethrin to H. rigida nymphs in culture resulted in a final mortality of 88.0 ± 15.2% after a 1-day exposure, and 100.0% after a 7 day exposure; initial permethrin concentrations in water were estimated to be 7.63 μg/L and maximum mean concentrations in sediment, measured 1 and 7 days after application, were estimated to be approximately 50 μg/kg dry weight. Exposure of nymphs to sediment contaminated 8 days previously resulted in 100.0% mortality. An application of 0.6 g/ha resulted in final mortality of up to 45.0 ± 4.1%. Lethal effects occurred in some cases between 1 and 4 and possibly up to 10 weeks after application.

Dans le cas des nymphes de Hexagenia rigida exposées à l'eau contaminée de perméthrine, sans sédimentation, au cours de l'expérience de 6 h LC50, on a estimé que le taux se situait entre 0.58 et 2.06 μg/L. Aucune nymphe n'a survécue à 6 h d'exposition à 7.63 μg/L. Une application simulée au laboratoire de 7.3 g/ha perméthrine à des nymphes de H. rigida en culture a eu pour résultat une mortalité finale de 88.0 ± 15.2% après exposition d'un jour, et 100% après exposition de 7 jours; on a estimé que les concentrations initiales de perméthrine dans l'eau furent estimées à 7.63 μg/L et des concentrations sédimentaires moyennes maximales mesurées 1 et 7 jours après application furent estimées à environs 50 μg/kg de poids sec. L'exposition des nymphes à des sédiments contaminés 8 jours auparavant a abouti à un taux de mortalité de 100.0%. Une application de 0.6 g/ha a eu pour effet un taux final de mortalité atteignant 45.0 ± 4.1%. Les effets mortels ont eu lieu, dans certains cas, entre 1 et 4, et possiblement jusqu'à 10 semaines après application.
