Tests were carried out on the effects of thiourea on a laboratory strain of Musca domestica L.. Oral administration appeared to be more effective against females and slightly more toxic to males at a concentration of 2 mg/g. In males, this dose appeared not to interfere significantly with the dynamics of sperm transport, production or motility. In females, however, it delayed oviposition and suppressed ovarian growth. Thiourea acted most favourably at concentrations from 1 to 2 mg/g diet. The sterility in cages containing males and females decreased by 87.02, 91.42 and 95.75% at 1, 1.5 and 2 mg/g diet, respectively, compared with untreated flies. Fecundity decreased appreciably when treated females were mated with untreated males. Flies did not survive for more than 10 days at a concentration of 10 mg/g diet.
