| Descripción: | 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 (Poecilia reticulata). Guppy fish (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 (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±100 c. Moreover, behavioral changes at each temephos concentration were observed for the individual fish.
