摘要

The current study was designed to evaluate the effects of some frequently used pyrethroid insecticides (Cypermethrin@ 0, 130,150 and 200mg/kg, Deltamethrin @0, 20, 25 and 30mg/kg, Permethrin@0, 150, 250 and 350mg/kg and Lambda Cyhalothrin @0, 30, 50 and 70mg/kg) on the behavior and clinical signs in albino rats, Rattus norvegicus underLab conditions. Feed intake, hind limb jerking, breathing problem, salivation, eye discharge, loss in body weight, lesion (internal organs), oedema, startle response, death were recorded at 7, 14 and 28 days of post application interval including a control (0-application of pyrethroid). The results revealed a reduction in feed intake and body weight against tested pyrethroid insecticides at all dose rates and post treatment intervals.
