Three disinfectants, i.e. Desoform, Lysoformin 3000 and Trichlorol were examined against fly larvae. The trial was carried out on the larvae of Calliphora vomitoria which were fed beef meat with aqueous solutions of the disinfectants under study. The concentrations used were as follows: Desoform -1,3,5 and 6%; Lysoformin 3000 - 0.7, 1.0, 1.5 and 2% and Trichlorol - 0.5, 1.0, 1.5 and 2.0%. The effect of each preparáte was compared with the control group. It was found that all the drugs destroyed the pupae of the fly. Desoform at a concentration 3% and 5% inhibited the development of the larvae at 80% and 95%, respectively, while 2% Lysoformin inhibited 90% of larvae. Trichloral turned out to be of minor effectiveness because its efficacy ranged between 11% and 42%.
