Screw-worm flies, Cochliomyia hominivorax (Coquerel), treated at different stages of the life cycle with N,N'-tetramethylenebis (l-aziridinecarboxamide), could not be sexually sterilized by incorporating the chemosterilant in the larval medium or by immersing prepuce in a solution however, screw-worm flies were sterilized successfully by immersing pupae, and sterility was induced in adults be all routes of administration: topical application, oral treatment, tarsal contact with a residual film, and injection. Oral administration to adults reduced the survival of treated flies at least half; the other routes had no adverse effects on survival. Topically sterilized males were at least fully competitive sexually, but males sterilized by tarsal contact or intrathoracic inoculation were less competitive than normal males.
