Abstract : There is a correlation between the amount of blood ingested by Aedes aegypti (L.) and the trypsin activity in the midgut 16 and 24 hr after feeding. Puromycin and dactinomycin ingested with a blood meal depress the level of midgut trypsin. Trypsin purified from the midguts of A. aegypti fed upon defibrinated blood containing (14)C-amino acids contains radioactivity. Midguts from blood-fed mosquitoes did not produce significant amounts of trypsin when dissected from mosquitoes and maintained in a tissue culture medium for up to 50 hr. (Author)
