[Comparative characteristics of the digestive enzymes of blood-sucking insects. II. Invertase and lipase].
The activity of invertase and lipase in the midguts of 11 hematophagous insect species have been determined. The highest invertase activity at pH 7-10. Insects feeding on carbohydrate meals as well as with blood have the greatest invertase activity, the obligatory blood feeders have the least one. The lipase activity does not depend on trophic peculiarities of the blood-suckling insects.
