Abstract

Attracticide resistance monitoring technique was used for measuring insecticide resistance in pink bollworm (P8W) male moths. Pectin°. phora gossypiella (Saunders). This technique eliminates handling of insects and is compatible with the current practice of monitoring populations with pheromone traps. Results showed that, P8W developed resistance to all insecticides tested with RR of 19 and 12.7 folds in early and late season 1996 for fenvalerate, 12.8 and 47.2 folds for chlorpyrifos, 14.1 and 34.7 folds for delfose, 14.1 and 38.5 folds for empire and 22.6 and 56 folds for thiodicarb, respectively. This technique was used to estimate discriminating concentration (DC) (LC90 of a field strain in 1996 early season) for the tested insecticides. The highest level of resistance ratio was 97.44 fold against thiodicarb in late 1997. while the lowest one was 13.18 fold against fenvalerate in late 1997.
