Abstract

The developing countries of theworld are facing a global challenge of feeding their explosively growing population. At the same time, the pests are becoming one of the major causes of preand post-harvest loses of crops. The different types of broad-spectrum, effective pesticides have been invented as a solution to this pest problem. However, Among these, the pyrethroid group of insecticides are commonly being used. This review describes only two pyrethroid i the slowmetabolism of these compounds in fishes aggravate their toxic effects. In this review, an updated account of the toxicological evaluation of both of these insecticides in terms of their environmental, physico-chemical, metabolic, biochemical and molecular aspects has been presentedwhichmay be useful in ecological risk assessmentandhumanhealthmanagement. nsecticides namely !-cyhalothrin and cypermethrin, which are extensively being used in different indoor and outdoor applications in order to kill the insects-pests. The recent reports the slowmetabolism of these compounds in fishes aggravate their toxic effects. In this review, an updated account of the toxicological evaluation of both of these insecticides in terms of their environmental, physico-chemical, metabolic, biochemical and molecular aspects has been presentedwhichmay be useful in ecological risk assessmentandhumanhealthmanagement.
