Characterization of a Stably Maintained, Highly Beta-Cypermethrin-Resistant Strain of the Bird Cherry-Oat Aphid Rhopalosiphum padi (Hemiptera: Aphididae)
Insecticide resistance threatens effective pest management. In this study on Rhopalosiphum padi, a predominant wheat pest, a field-derived beta-cypermethrin-resistant strain (Beta-R strain) showed a 4623.50-fold resistance increase after 22 generations of beta-cypermethrin exposure and remained highly resistant (>4000-...
