Species sensitivity distribution of a freshwater Arthropoda community to the insecticide esfenvalerate in the south of Western Siberia
The sensitivity of the insect larvae <i>Aedes cinereus</i>, <i>Anopheles messeae, Ochlerotatus caspius</i>, <i>O. euedes</i>, <i>Chaoborus crystallinus</i>, <i>Sympetrum flaveolum, Lestes sponsa </i>and <i>Plea minutissima</i>, and crustaceans <i>Daphnia magna</i>, <i>D. longispina</i>, <i>D. pulex</i>, <i>Simocephalus vetulus</i>, <i>Scapholeberis mucronata</i>, <i>Eudiaptomus graciloides</i>, <i>Cyclops strenuus</i>, <i>Gammarus pulex</i>, <i>Lynceus brachyurus </i>and <i>Cypris pubera </i>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.
