To identify alternatives to the long-used trichlorphon the mixture of chlorpyrifos and cypermethrin (10:1) was tested against adults and nymphs of litchi (Litchi chinensis) stink bug. The mixture was highly effective against overwintered adults. Treatment with the mixture at a concentration as low as 138 ppm caused 100% mortality after 7 days compared to 1125 ppm trichlorphon. Although the mixture caused less mortality than trichlorphon on the first day, it gave 100% mortality of adults.
