Insecticidal effect of Dimetilan on house flies (II) : Laboratory studies on several baits for the control of Diazinon-resistant and susceptible house flies

Abstract

Laboratory tests were conducted on the effectiveness of 6 fly bait products against Diazinon-resistant and susceptible house flies (Musca domestica). A product containing Dimetilan (3-methyl-5-pyrazolyl dimethylcarbamate) as an active substance of a bait product was effective against both of the strains in the laboratory cage tests and superior to other bait products as a whole, i.e., B, containing Dipterex, C, DDVP and Diazinon, D, DDVP, and E, DDVP, but F product containing DDVP and Lindane was as effective against Diazinon-resistant flies as A product. However, in the room test concerning attractiveness and toxicity, A product was superior to F product. D, E and F products indicated high vapor effect. Also in evaluation on duration of effectiveness, A product was excellent. Dimetilan, as a bait treatment, would offer promising results for controlling Diazinon-resistant house flies known in Japan.
