AbstractThis study was conducted to investigate the accumulative and non-accumulative effects of water and organic leaves extracts of Nerium oleander on larval instars of Culex quinquefasciatus. The organic extracts were more effective on larval instars of Culex and the petroleum ether extract was the most effective one. The first larval instars had the least resistance to water and organic extracts in comparison to other instars. The petroleum ether extract of Nerium oleander produced 2 constituents on thin layer chromatography A and B, the first one (A) was the most effective on larval instars of Culex.
