Two days following treatment, larval populations of Aedes albopictus in waste tires treated with granular formulations of temephos were reduced 90% at the 0.11 kg AI/ha rate, 98% at the 0.56 kg AI/ha rate, and 100% at the 1.12, 11.21, and 22.42 kg AI/ha rates. Nearly 100% control was achieved for 8 wk at the 0.5 kg AI/ha rate, for 7 wk at the 1.12 kg AI/ha rate in one replicate, and for at least 5 months at the 11.21 and 22.42 kg AI/ha rates. These results indicate that prolonged control can be achieved with granular formulations at half (11.21 kg/ha) the maximum label rate and that excellent immediate control can be expected at 2.5% the maximum label rate.
