Gas-Propelled Aerosols and Micronized Dusts for Control of Insects in Aircraft. 6. Insects of Medical Importance1
In 2 types of exposure in truck trailers, micronized insecticidal dusts (2 g/1000 ft3) of chlorpylifos, fenitrothion, Mobam® (benzo[b]thien-4-yl-methylcarbamate), and propoxur were the most effective of the singletoxicant formulations against normal specimens of Blattella germanica (L.), Cimex lectularius L., Periplaneta Americana (L.), and Xenopsylla cheopis (Rothschild). The most effective multiple-toxicant formulations, at doses of 2 g/1000 ft3, contained chlorpyrifos, Gardona® (2-chloro-I-(2,4,5-trichlorophenyl)vinyl dimethylphosphate), propoxur, or resmethrin, and those con taining chlorpyrifos, Mobam, propoxur, or resmethrin were also effective against these species at doses of g/1000 ft3. When the more effective dust formulations in the truck trailers were tested in passenger aircraft, the distribution of the dust particles was not satisfactory, and the insects, representative of insects of medical importance that might be introduced via air transport, were not controlled; therefore, the present technique for application of micronized dusts in aircraft must be revised. The most effective insecticidal aerosols (30 or 10 g/1000 ft3) in the truck trailers were resmethrin and trans- (+)-allethrin; however, when these formulations were used at a rate of 10 g/1000 ft3 in aircraft, they were less effective. Aerosols of resmethrin had residual activity against the test species.
