Laboratory investigations on the chemical disinfection against different developmental stages of the housefly (Musca domestica LINNAEUS, 1758)

Possibilities for disinfection of the developmental stages from the housefl y (Musca. domestica) were investigated under laboratory conditions. The dev elopmental stages (eggs, larvae I, II, III, pupae and adults) were sprayed with solutions of disinfectants on the basis of p-chlorine-m-cresol and o-p henylphenol at different concentrations (0,025 %-3 %). The effectiveness of both disinfectants was established by determining the emergence rate of eg gs and pupae and of the live evidence of larvae and adults, Transmission el ectron microscopic investigations of the cover of the eggs revealed the bac tericidal effect of both disinfectants. These results show the necessity of extending its use also to noxious arthropods.
