< p > The increasing of using pesticides are the major threat to natural ecosystems and organisms. Accordingly, the aquatic organisms especially Artemia sp are being used in determining the lethal and legislation concentration of these compounds. The present study was carried out to investigate the lethal effect of Abamektin pesticide which is used in Sistan area for agriculture and domestic activities, on nauplii 24, 48h and adult Artemia urmiana. This study was also focused to evaluate the effects of Abamektin toxicity on stages of A. urmiana. The lethal concentration including LC10, LC15, LC50, LC85, LC90, LC95 and LC99 were determined with Probit analysis program for three groups of A. urmiana after 24 hours exposure and conducting a range definitive Abamektin in static process according to O.P.D.C 202 protocol. Results showed the highest mortality rate was observed for adults in comparing to 24h nauplii and the adults were higher sensitive in comparing to other groups. The LC50 amounts were determined 4.72, 1.15 and 0.726 µg/l for 24h, 48h nauplii and adult respectively. These results indicate that Abamektin is a very high environmental toxic substance.
