Abstract : This paper represents the distribution of enzymes alkaline and acid phosphatases, were studied in the alimentary canal of Khapra beetle. It is observed that these enzymes were localized only in the midgut region. Both foregut and hind gut showed negative reaction. In the lower part of the midgut, a very high concentration of alkaline phosphatases was observed, whereas, the upper part of midgut showed relatively lesser concentration of these enzymes. A moderate reaction was observed throughout the midgut region of acid phosphatases which was found to be localized mainly towards lumen and peripheral sides but no effect of environmental pollutants on the gut of Trogoderma granarium (Evert).
