dc.description.abstractGlutathione S-transferase activities in field populalions (Fo) of the maize weevil, Sitophilus zeamais, were compared with their 3rd generation (F,) progeny which were reared in the laboratory. Two substrates, 1 -chloro-2,4-dinitrobenzene (CDNB) i and glutathione (GSH) were used in the tests and the Michaelis constant (K,,,) was determined for both these substrates. Enzyme activity was detected using the CDNB as the model substrate. The K,, values using CDNB were lower for the field populations compared to the F, progeny which were reared without any exposure insecticides. The data indicate that the insects collected from the field were better able to metabolise xenobiotics than their laboratory reared progeny wl-iich were not exposed to any insecticides.en_US
