Heliothis Resistance Monitoring: Effect of Age and Gender of Moths on Cypermethrin Susceptibility

Alton N. Sparks, Jr., John N. Norman, Jr., Jimmy R. Raulston, and Dan A. Wolfenbarger


The F1 generation adults from paired matings of field collected larvae were tested for cypermethrin susceptibility using the vial technique at ages of 1, 3, and 5 days. Both males and females were tested. LC(50) calculations indicated no significant effect due to age or sex of the adult moths tested.
