In 1997, resistance was again documented in tobacco budworm populations to pyrethroid insecticides. Over 745 tobacco budworm moths were bioassayed for pyrethroid resistance from May through August 1997 using a discriminating dose of 10 Fg in the adult vial test. Pyrethroid resistance levels were the highest documented since inception of monitoring in 1987. Percent survival in June was 51%. Previously, the highest level of survival observed in June between 1987 and 1996 had been 29%. This data indicates there was an increased use of pyrethroids in June 1997. Over 1821 male bollworm moths were assayed against a 5Fg/vial dose of cypermethrin. Bollworm moth survival levels continue to increase slowly. July survival levels were 14% , the highest observed since inception of monitoring in 1988. This data indicates that bollworm susceptibility to pyrethroid insecticides is changing.
