Rate of Digestion of 51Cr-Hemoglobin by Stomoxys Calcitrans (Diptera: Muscidae)

摘要: Bovine hemoglobin labeled with 51Cr was used to follow the digestion of blood meal in Stomoxys calcitrans and determine rate 51Cr-labeled excretion free 51Cr. Digestion by untreated flies fed only fresh, labeled, heparinized bovine began within first hour postfeeding completed 48 h: did not begin treated (flies soybean trypsin inhibitor blood) for ca 24 h. After h, control same. Excretion at about 4 h flies. Labeling chromium can be vivo is also useful determining volume meals.
