Abstract
The present study examines the effect of alpha-methrin and actara insecticides after administering certain medium lethal dose (LD50) to these insecticides, as well as studying the effect of the different doses from the two insecticides on some biochemical parameters in serum blood of males albino rats. The result showed significant decrease in total protein, albumin and globulin levels in serum of the rats treated by alpha-methrin whereas they increased in rats treated by actara, and the results showed decreased uric acid concentration in rats treated by both insecticides. The conclusion from this study was that alpha-methrin insecticide was considerably more poisonous than actara insecticide.
