“…40 The effects may be observed in a non-liner manner in subsequent generations. 41 Similarly report Kafel et al 42 on different effect of Cd (44 and 66 µg/g dry weight of diet) and Zn (200 µg/g dry weight of diet) in fat body of S. exigua showing significantly increses at higher concentration. In our results GST activity of metal treated Spodoptera litura midgut tissues shows significantly increased activity in Cd 0.44 mg, Pb 9.6 mg, Pb 4.8 mg, as compared to control.…”

“…Similarly Adamski et al (2003) and Yu (2004) found fluctuations in the activities of different enzymes in fat bodies after the exposure of insects to different chemicals. Fat bodies are supposed to be sensitive to toxicity and play a vital role in the detoxification of insecticides with increased enzyme activities, as Kafel et al (2003) (Timmins and Reynolds, 1992). Enhanced activity of antioxidant enzymes play an important role in the insect immune system and can be a cause of resistance.…”

“…Exposure of fish to heavy metals has been shown to compromise several aspects of humoral and cell-mediated immunity and many enzymatic activities (Lemaire-Gony et al 1995). Cd, in particular, has been shown to affect phase I (cytochrome P450) (Viarengo et al 1997a) and phase II [glutathione-S-transferase (GST)] enzymes (Kafel et al 2003). GSTs are essential components of the cellular antioxidant defence system, as they catalyze the conjugation of GSH to several dangerous compounds (Arrigo 1999;Rahaman et al 1999).…”
