Residual efficacy of the insect growth regulator pyriproxifen for controlof stored product insects


Abstract: The insect growth regulator pyriproxyfen is registered in the USA as an aerosol and asa surface treatment to control stored product insects. Field trials with the aerosol show thatresidues from an application of pyrethrin + pyriproxyfen gave residual control of Triboliumcastaneum Herbst for at least 10 weeks. Laboratory tests with pyriproxyfen alone as a surfacetreatment gave greater residual control compared to hydroprene, even though the applicationrates for pyriproxyfen were 5 to 10 times lower than the label rate for hydroprene. Results showthat pyriproxyfen could be incorporated into management programs to control stored productinsects.
