title: [Residual action of Neguvon, Neocidol, Nuvanol and Dursban on the imaginal and larval stages of the housefly].
abstract: It is shown that Dursban, Neocydol and Neguvon preparations, mixed with swine manure at amounts of 500 mg/kg, kill 100 per cent the larvae of the domestic fly up to the 30th, 20th and 10th day, respectively, while the Neguvon and Neocydol preparations in cattle manure, up to the 10th day. Lower concentrations possess a residual effect of a shorter duration. It is also shown that the type of the surfaces and the pH of the mater on which the preparations are placed markedly affect the inctesicide activity and the residual effect of the preparations. The highest activity and the longest residual effect manifest preparations that have been placed on surfaces with a low absorption capacity. The highest effect has been achieved when the preparations are smeared on glass, a lower one, when placed on wood, and the poorest, when laid on mortar.
