Over 6900 male tobacco budworm moths were bioassayed for pyrethroid resistance from May through October l992 against 10 or 30 µg doses of cypermethrin utilizing the adult vial test. Average pyrethroid resistance levels during May and June of 1992 were similar to that recorded previously (1987-1991). These data indicate that the Insecticide Resistance Management Plan for Louisiana has been successful in stabilizing the level of pyrethroid resistance during the non-pyrethroid insecticide use period. However, average pyrethroid resistance levels during July, August and September of 1992 were higher than during the previous five years. Thus except for 1991, overall levels of pyrethroid resistance have increased each year during the pyrethroid use period. Topical application bioassays of larval progeny of several field collections of tobacco budworm made in 1992 indicated significant resistance to carbamates, organophosphates and organochlorines. As a result of insecticide resistance and persistently high tobacco budworm populations, numerous field control failures occurred during 1992. Over 3400 male bollworm moths were bioassayed against 1,2, or 5 µg/vial doses of cypermethrin. Data from these bioassays were similar to that obtained in 1988-1991 and indicate that bollworms remain susceptible to pyrethroids.
