A genetic technique was employed to test for dominant and recessive heat-sensitive genetic factors on chromosome III of Musca domestica L. following treatment of house fly sperm with ethyl methanesulfonate. No dominant mutations were detected, but 10 recessive heat-sensitive mutants (hs) were recovered which survived when reared at 25±2 but died when reared at 33±2. Lethal expression tests showed that 3 of the hs factors were expressed in the larval stage, while all remaining mutants caused death at various stages of pupal development. Temperature -sensitivity patterns established for each mutant indicated that little time elapsed between the temperature- sensitive period and the onset of death with any of the hs factors.
