Abstract :ABSTRACT Temephos   is an organophosphorus   insecticide used to control mosquito, midge and black fly larvae. This   study was aimed to determine the acute toxicity of temephos on behavior of the guppy insert ignore into journalissuearticles values(Poecilia reticulata);. Guppy fish insert ignore into journalissuearticles values(Poecilia reticulata); were selected for the bioassay experiments. Behavioral changes at each temephos concentration were recorded. The experiments were repeated 3 times. The 96 h acute toxicity range of temephos to adult male guppies was within 10 and 100 mg/l insert ignore into journalissuearticles values(mean >50 mg/l);. At 100 mg/l dose, all fish died within 96 hours. In addition, no changes in behavior were observed at the lowest concentration of 1 mg/l. Water temperature was regulated at 21±10 0 c. Moreover, behavioral changes at each temephos concentration were observed for the individual fish.   Key Words: Acute toxicity; Guppy; Temephos; Bioassay; Organophosphorus insecticide¸ Behavioral changes
