![]() ![]() Le but de cette étude a été de tester la sensibilité de deux espèces communes de zooplancton, Daphnia pulex Ley dig, 1860 et Tumeodiaptomus diabolicus (Brehm, 1935) au fongicide carbendazime. Au Chili, on observe une utilisation accrue de fongicides, en particulier dans le centre et le sud du pays. These results indicate that the two native Zooplankton species of Chilean Patagonian lakes are considerably more sensitive to the pesticide carbendazim, than the species D. pulex had a 48-h LC₅₀ of 26.1 μg/1, and finally D. diabolicus had a 48-h LC₅₀ of 28.1 μg/1, while D. In parallel, also literature information on the commonly used D. The specimens came from Lake Calafquén (southern Chile), and were subjected to bioassay experiments under laboratory conditions over 48 h to seven carbendazim concentrations (0-77.70 μg/1) these bioassays were performed using adult specimens. The aim of this study was to test the sensitivity of two common Zooplankton species, Daphnia pulex Ley dig, 1860 and Tumeodiaptomus diabolicus (Brehm, 1935) to the fungicide carbendazim. In Chile there is an increased use of fungicides, especially in the central and southern parts of the country. ![]()
