Abstract: A trial was carried out to test the efficacy of cyromazine (Neporex) against third-instar larvae of laboratory strain of Musca osiris Wiedemann, 1830. Its effect was studied at 0.1, 0.5, 1 and 2 ppm concentrations in rearing medium. It can be established that cyromazine is effective against previously not tested M usca osiris. Parallel to a decrease of drug concentration the effect became less pronounced. The larvae were able to develop and to pupate at each concentration but a significant part of the resulting pupae were deformed. Most of them were rod-like, C-shaped, elongated or smaller than the normal ones. At higher concentrations (1 and 2 ppm) the development of adults from pupae was completely prevented. At lower concentrations (0. 5 and 0. 1 ppm) the extent of abnormality varied from no eclosion to complete eclosion. At a level of 0.5 ppm pupal mortality was 64 per cent. There were two incomplete adult eclosions. At the lowest concentration pupal mortality was 48 per cent. In 16 cases the imagos died at different stages of hatching.
