title: Crop and midgut filling and emptying in a female Phormia regina (Diptera: Calliphoridae) fed a liver diet.
abstract: To study the role of the crop in protein storage, crop and midgut filling in female Phormia regina (Meigen) was measured volumetrically and the soluble protein content determined. During a 4-h feeding period on homogenized liver, nonligated females consumed and stored enough protein in the crop and midgut to develop a normal compliment of eggs. Within 26 h from the onset of feeding, 75% of the protein content of the crop and a similar amount from the midgut were emptied. Neck ligation or sham neck ligation 7 h after females fed to repletion slowed but still allowed delivery of sufficient protein for egg development.
