RESUMO
In Miami, Florida, USA, passenger compartments of jet aircraft were disinsected at "blocks away". An application of a 20 g/litre Freon-based or water-based permethrin formulation at 35 mg of aerosol per 100 m(3) was 100% effective against caged mosquitos and flies. The flammability hazard of the sprays from water-based hydrocarbon aerosols was evaluated.

In Miami, USA, passenger compartments of wide-bodied jet aircraft were disinsected at "blocks away" or while parked. The application of 2% Freon- and water-based formulations of (+)-phenothrin at about 35 g/100 m(3) was highly effective against mosquitos and flies in all instances. More basic research is needed on water-based aerosols.

A 2% formulation of (+)-phenothrin dispensed from 340-g or break-off tip aerosol cans was highly effective against mosquitos in aircraft disinsection trials. Two minutes after application at "blocks away", the mass median diameter of the dispersed drops was 5.1-6.2 mum. The concentration of the insecticide in the cabin fell to 10% of the original concentration after 9.2 min. No odour or irritation was caused by the use of this insecticide.

Of several aerosol formulations of 3 synthetic pyrethroids, S-2539 Forte, resmethrin, and bioresmethrin, the 2% formulation was most effective for the disinsection of passenger spaces aboard jet aircraft; the 1.2% and 0.3% formulations were less effective. Break-off tip aerosol units gave good dispersal, but these limited production cans showed slight variability in the rate of release.
