Infecundity and dominant lethal mutations induced in Musca domestica L. by sodium azide (NaN3).

Results of our study suggest that sodium azide is effective in the induction of sterility and dominant lethal mutations in both sexes of M. domestica L. When treated males were crossed with nontreated females, 100% dominant lethal mutations and 72.3% infecundity were found, whereas in the crosses of nontreated males and treated females, 82.5% dominant lethal mutations and 33.1% infecundity were found. This showed that males are more sensitive to sodium azide than females.
