Lhb. Kanga et al., A 4 YEAR STUDY OF RESISTANCE TO ORGANOPHOSPHORUS, CARBAMATE, AND CYCLODIENE INSECTICIDES IN THE TOBACCO BUDWORM IN TEXAS AND ARKANSAS, The Southwestern entomologist, 20(3), 1995, pp. 237-246
Resistance to organophosphorus, carbamate, and cyclodiene insecticides
in field populations of the tobacco budworm (TBW), Heliothis virescen
s (F.), from Texas was documented in 1991. The seasonal pattern of res
istance from 1991 to 1994 was similar each year in that resistance inc
reased midseason and declined in late season. Resistance gene frequenc
ies were highest in 1992. A vial test was successfully used to monitor
for resistance to these insecticides in adult TBW. The test provided
valuable information for the development of a resistance management st
rategy designed to extend the efficacy of insecticides used to control
cotton pests.
