Pyrethroid resistance monitoring was continued for the eighth consecutive year. Data collected this year showed a great reduction in midseason tobacco budworm populations. When tobacco budworms finally arrived, resistance was already present at a high frequency. The result was that pyrethroid insecticides were never needed for budworm control. Possible reasons for the late arrival of tobacco budworms and alternate strategies for managing budworm populations are discussed. |
