RESUMEN
Extension of day length by artificial light in selected field plots in the fall prevented 76 percent of European corn borer [Ostrinia nubilalis (Hübner)] larvae and 70 percent of codling moth [Laspeyresia pomonella (L.)] larvae from entering diapause. Nondiapausing insects cannot survive rigorous winter conditions.

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.

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.

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.

The action spectrum for breaking diapause in the oak silkworm, Antheraea pernyi Guer., and the codling moth, Laspeyresia pomonella (L.), was determined from 400 to 700 nm with a wedge-interference spectrograph. Insects were exposed to ten hours of white light, followed by six hours of spectral light each day for 45 days. The portion of the spectrum between 400 and 500 nm was found to be the most effective in terminating diapause. Diapause was broken for both insects with energy levels as low as 0.02 muw/cm(2).
RESUMEN
During 1971 worldwide experiments on the disinsection of passenger cabins at "blocks away" (as the aircraft starts taxiing for take-off) were conducted in several types of jet aircraft. A procedure was developed whereby the high capacity Boeing 747 could be disinsected by four stewardesses in less than 1 minute. The favourable results of these and previous trials indicate that this method is suitable as a standard procedure for aircraft disinsection for international quarantine purposes.The biological effectiveness against resistant and non-resistant mosquitos of a 2% concentration of a pyrethroid, resmethrin, in Freon 11+Freon 12 (1:1) (without kerosine) and a favourable passenger response make it suitable as a standard formulation for aircraft disinsection.

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.
