Aquatic organisms are used to assess the health of aquatic systems. Extensive use of pesticides in agricultural and public health programs causes many environmental problems and toxic effects on aquatic animals especially against non-target organisms such as non-target organisms for mosquito larvae Plea minutissima Leach, 1817 and cladoceran biofilter and biomarker Daphnia magna Straus, 1820. These biological models were selected for their importance in the food chain and in the maintenance of homeostasis. Rustile is a multi-purpose toxic insecticide, manufactured by SARL DEKACHIM, consisting of 20% of the active ingredient Acetamipride. The lethal doses used for the insecticide in the treatment of these two non-target groups were LC50 = 1.45 ml/l and LC90 = 1.90 ml/l. The superiority of Culex pipiens larvae was recorded during three days of treatment. Both types showed a variable response to the tested product depending on doses and exposure times. Toxicity assays clearly showed a variable sensitivity of the two treated species recorded at high rates. The maximum values recorded were 86% and 97% for LC50 and LC90, respectively. It was found that rusty pesticides affect the two non-target tested species. The most sensitive species to this pesticide was Daphnia magna. [ABSTRACT FROM AUTHOR] |
