Task: Answer Verification
Input (English): Question: Do differences in nicotine metabolism of two Nicotiana attenuata herbivores render them differentially susceptible to a common native predator?
Answer: Nicotine oxidation reduces S. exigua's headspace-nicotine and renders it more susceptible to predation by spiders than M. sexta, which exhales unmetabolized nicotine. These results are consistent with the hypothesis that generalist herbivores incur costs of detoxification, which include the ecological costs of greater predation risks, in addition to the previously demonstrated energetic, physiological and metabolic costs.
Output (English): yes
