Tsetse hybrids

W. H. Potts,  Nature,  154:606-607. 1944.

N 1936 I attempted to cross various species of tsetse (Glossina) with the idea that, should they hybridize readily, and should the resultant hybrids prove sterile, this might be tried as a measure of control. Corson had already, in 1932, obtained three offspring from crosses between male G. swynnertoni and female G. morsitans; he suggested, however, that these might not be true hybrids, but the result of parthenogenesis (see further details in the accompanying communication by Mr. F. L. Vanderplank). I obtained a number of offspring from this and other crosses, but as a slight doubt arose as to whether they were authentic hybrids, the results were never published.
