ABSTRACT
Detailed monitoring was conducted of resistance to synthetic pyrethroid (SP) insecticides in tobacco budworm, Heliothis virescens (F.) males collected in pheromone traps near College Station, TX in 1986. Resistance levels varied from near zero to > 90% during the season. A management scheme is proposed which would utilize nonpyrethroid insecticides early in the season and pyrethroids + chlordimeform midseason. Such an approach may allow continued use of SP Insecticides even though resistance is present.
