Abstract
The control of crop emptying in the blowfly, Phormia regina, was investigated by the technique of X-ray photography. Increasing the osmotic pressure of the solution in the crop slows crop emptying. This effect is independent of the nutritive value, stimulating power, and viscosity of the solution. Increasing the osmotic pressure of the blood also greatly slows crop emptying. Blood osmotic pressure is the controlling factor. The effect of increased blood osmotic pressure in slowing crop emptying is independent of nervous or endocrine elements.
