Abstract
It is a well known fact, noticed by many workers engaged in breeding hymenopterous parasites, that there is a tendency in many bisexual species for the sex-ratio to decrease as the breeding work proceeds over a series of generations. In a number of cases the sex-ratio decreases to an extent where only males are produced, and the stock dies out.Keywords
