Species sensitivity distribution of a freshwater Arthropoda community to the insecticide esfenvalerate in the south of Western Siberia
The sensitivity of the insect larvae Aedes cinereus, Anopheles messeae, Ochlerotatus caspius, O. euedes, Chaoborus crystallinus, Sympetrum flaveolum, Lestes sponsa and Plea minutissima, and crustaceans Daphnia magna, D. longispina, D. pulex, Simocephalus vetulus, Scapholeberis mucronata, Eudiaptomus graciloides, Cyclops strenuus, Gammarus pulex, Lynceus brachyurus and Cypris pubera to the pyrethroid insecticide esfenvalerate in the toxicological tests are given. The LC50 values were determined and a species sensitivity distribution model of the freshwater Arthropoda was fitted. Calculations of hazardous concentrations for 5 % and 50 % of the species were also determined.
