Control of Musca domestica L. adults with pyrethroid treatments applied to glass and wallpaper

Abstract

Cypermethrin (CP), cypermethrin trans-tetramethrin (CT), prallethrin (PR) and diazinon (DI) were applied to wallpaper or glass to evaluate the control of adult houseflies of up to 60 days; immediate mortality from direct spraying and dry residues was also determined. Mortality from fresh residues was greater on glass for all pyrethroids. CP was toxic by direct spraying, but its effect on glass was brief. Adding trans-tetramethrin extended CP activity up to 60 days (mortality 77%). Negligible activity on wallpaper was probably due to insecticide absorption. PR and DI had little effect on wallpaper. The results recommend CT applied to glass windows to achieve extended control.
