We consider using non-host plants that express both a toxin and oviposition deterrence for to increase stability for insect resistance management. The two traits reinforce each other ecologically. We used a two-gene model to evaluate this combination of traits. When toxin resistance was recessive or partially recessive, even moderate levels of oviposition deterrence extended time to resistance. When sensitivity to oviposition deterrence started at a low frequency (0.001) selection pressure from the toxin caused the frequency of the gene for sensitivity to oviposition deterrence to increase and the time to resistance was extended beyond the 150-y timeline of the simulations. Even in the worst-case scenario, when toxin resistance was dominant, oviposition deterrence extended time to resistance up to 150 y. The genes for toxin and sensitivity to oviposition deterrence support each other ecologically to prevent resistance from developing to either trait. This creates a more stable insect resistance management strategy.
