Research
<p><strong>Background:</strong> The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to assess mortality effects of these chemicals to the Mosquito <em>Culex</em> <em>quinquefasciatus</em>.</p>
<p><strong>Methods:</strong> This study was carried out in Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran at summer 2013. <em>Culex</em> samples were exposed to different concentrations of butachlor and pertilachlor (0-200ppm for butachlor and pertilachlor) for 96 h.</p>
<p><strong>Results:</strong> The low toxicity of LC50s obtained for butachlor (23.81±0.04) and pertilachlor (27.97±0.05) indicate that butachlor and pertilachlor were lowly toxic to Mosquito <em>Cu.</em> <em>quinquefasciatus</em>.</p>
<p><strong>Conclusion:</strong> Although pretilachlor and butachlor are low toxic but pretilachlor is less toxic in field conditions, these data are useful to potential ecosystem risk assessment.</p>
