Hybridization has been studied in mosquitoes ever since caged colonies began to be maintained. Aedes particularly of the subgenus Stegomyia have been crossed variously at different times and by different observers. Anopheles species, particularly some of the subgenus Anopheles, have been hybridized with varying results. However techniques for inducing copulation developed in this laboratory (McDaniel and Horsfall, 1957) and used on Culiseta, Psorophora and many Aedes make possible combinations unlikely by chance in cages. Cage adaptation is not a prerequisite for success neither are precopulatory stimuli.
