 \[[Fig. 0](#fig0){ref-type="fig"}A\] showed the alpha-glucosidase activity in flies raised on diet supplemented with TA or GA (0.0 and 0.0 mg/g). This showed that alpha-glucosidase activity in flies raised on diets supplemented with TA or GA were significantly lower *(p \< 0.00)* to that in flies raised on basal diet. There was however, no significant difference *(p \> 0.00)* in the alpha-
