Abstract
IN the desert locust (Schistocerca gregaria Forsk.) copulation occurs frequently, although once fertilization has taken place further copulation appears to serve mainly as a stimulant to egg-laying and to be unnecessary for renewed fertilization1. An interesting problem arises as to whether, after a second copulation, eggs are fertilized by sperm from the first or the second copulation. The following experiment was devised, using an albino stock of Schistocerca. It has been shown previously that crosses between albino and normal adults show a Mendelian pattern of inheritance, in which albinism is recessive2.
