INVESTIGATION of SEVERAL AEROSOL INSECTICIDE COMPOSITIONS CONTAINING SYNERGISTS

Abstract:
Two aerosol insecticide compositions were investigated in laboratory conditions against a complex of synanthropic insects. Both compositions have high acute insecticidal activity and have a long residual effect on glass, but not on plywood. It is shown that the knockdown effect was reversible on plywood on the 3rd and 7th days after treatment for cockroaches and on the 7 th day for bugs. Fifteen aerosol compositions containing cypermethrin, imiprothrin alone or mixed with the synergists piperonyl butoxide and/or MGK-264 in different concentrations were prepared specially for laboratory use and were investigated. It is shown that the synergism ratio was higher in houseflies than in cockroaches in compositions containing PBO, but it was higher in cockroaches when it contained an MGK-264-like synergist.
