Elaboration and testing of insecticidal varnish in aerosol containers for the control of synanthropic cockroaches.
A formula for the filling of aerosol containers has been elaborated on the basis of a mixture of hexachlorocyclohexane (HCH) gamma isomer and tetrametrin, in a ratio 3:1 with the addition of furniture varnish NC-62 to produce the film, Khladon 11/12 (5050) served as propellent. The study of the process of crystallization of the insecticides on the surface of the film has shown that the effectiveness of insecticidal varnishes is the higher, the smaller the size of the crystals and the easier they can be removed from the surface of the film. This can be achieved by including tetrametrin along with HCH gamma isomer in the formula. The testing of the insecticidal activity and toxicity of aerosols prepared according to the elaborated formula has demonstrated high insecticidal activity of the composition with respect to synanthropic cockroaches and fairly low toxicity with respect to warm-blooded animals.
