Abstract: The experimental observations on Chong-Di Emulsion, a new insecticide which developed from Ji-Kun Institute of Disinfection technique, against sanitary insects has been conducted both in laboratory and field. The result showed that the KT₅₀ for house-fly was 1.6018 minutes. The deathrate of 24 hr. was 100%, while the agent was dilated at the concentration of 100 times, then spraied on glass surface at the concentration of 100ml/m². In the field trail the experiment of the emulsion against maggot of flies was carried out, the rate of density in maggot was obviously fallen-100%, if could be lasting for 30 days.If it is diluted at 500 times, daubing on the surface of glass at the concentration of 100ml/m², The KT₅₀ for Culex pipiens was at 3.5167 minutes, the death-rate of 24 hr. was 100%, while diluting at the concentration of 1000～10000 times, the deathrate for Culex pipiens was 100%, and it could be lasting for 27 days. Diluting it at 300 times, painted its on bricks surface at the concentration of 200 ml/m², The KT₅₀ for house-fly was at 1.560 minutes, the death-rate of 24 hr. was 100%. Dilnting it at 109 times, the KT₅₀ for Blattellagermanica wasat 3.3289 minutes, and the death-rate of 48 hr. was 100%. Suming up the main point mention above the Emulsion of Chong-Di is excellent insecticide for sanitary insects, it possess quickly killing effect and knock down functions against sanitary insects.
