Influence of the bioinsecticides, NeemAzal, on main body metabolites of the 3rd larval instar of the house fly Musca domestica (Diptera: Muscidae)

The present study was designed and conducted to determine the effects of Neemazal on the general body metabolism of the house fly Musca domestica. The second instar larvae of the house fly M. domestica (L.) were reared on artificial diet treated with the botanical extract, NeemAzal. Five concentration levels of this compound (1000, 500, 250, 125 and 62.5 ppm) were used. The main body metabolites,...

Effects of 4-nonylphenol on metabolic enzymes, some ions and biochemical blood parameters of the African catfish Clarias gariepinus (Burchell, 1822)

In present work, some biochemical characteristics of the catfish, Clarias gariepinus were studied under the effect of different sublethal doses of 4-nonylphenol (0, 0.05, 0.08 and 0.1 mgl-1). Liver enzymes ALT and AST increased insignificantly at P<0.05 whereas the ALP decreased insignificantly. The activities of G6PDH showed significant increase with the increased sublethel doses of 4-nonylphenol...
