Digestive enzyme activity in the gut of the adult apple maggot rhagoletis pomonella



Digestive enzyme activity in the gut of the adult apple maggot rhagoletis pomonella



Annals of the Entomological Society of America 70(3): 417-421



The presence of .alpha.-glucosidase-like activity was shown in the gut of the adult apple maggot (Diptera: Tephritidae). Activity in the midgut was slightly higher than in the foregut and hydrolysis occurred faster at 37.degree. than at 22.degree. C. Hydrolysis of a number of .alpha.-glucoside sugars suggested the presence of .alpha.-glucosidase rather than invertase. Tests for proteases were negative.
