Abstract

When new laid eggs of the house cricket are treated with a potassium biphthalate buffer (0.05 M) at pH 4.01 for 1 h, followed by a Na2CO3 solution at pH 11.0 for 22 h at room temperature, the chorion lifts off the surface of the egg; by cutting off the end of the stretched chorion, the dechorionated egg may be pushed out of the shell. Dechorionated eggs behave in a different manner towards sucrose and salt solutions than do intact eggs. These and other experimental results are discussed in relation to the physiology of water absorption.
