摘要 : The sensitivity of seven zooplankton species (<i>Daphnia magna</i>, <i>D. longispina</i>, <i>D. pulex</i>, <i>Simocephalus vetulus</i>, <i>Scapholeberis mucronata</i>, <i>Eudiaptomus graciloides</i>, and <i>Cyclops strenuus</i>) t... 展开 The sensitivity of seven zooplankton species (<i>Daphnia magna</i>, <i>D. longispina</i>, <i>D. pulex</i>, <i>Simocephalus vetulus</i>, <i>Scapholeberis mucronata</i>, <i>Eudiaptomus graciloides</i>, and <i>Cyclops strenuus</i>) to an insecticide, sumicidine alpha was studied. LD₅₀ values upon a 24-hour exposure were determined. <i>Daphnia pulex</i> and <i>D. longispina</i> turned out to be highly susceptible to the insecticide, while the individuals representing the natural population of <i>D. magna</i> happened to be the most resistant. The data on sensitivity distribution among different zooplankton species are provided, as well as the concentrations potentially hazardous for 5% and 50% of the population are calculated.Notes Translated from <i>Sibirskii Ekologicheskii Zhurnal</i> (2011) <i>18</i>, 497-503 (Ru).Digital Object Identifier http://dx.doi.org/10.1134/S1995425511040047 收起
