Differences in the Detoxification Metabolism between Two clonal Lineages of the Aphid Myzus persicae (Sulzer) (Hemiptera: Aphididae) Reared on Tobacco (Nicotiana tabacum L.)

Myzus persicae (Sulzer) is a highly polyphagous aphid species, with a subspecies (M. persicae nicotianae) well adapted to tobacco (Nicotiana tabacum L.). We evaluated the effect of this host plant on the aphid performance and detoxification enzymes, in order to test the participation of xenobiotic m...

In order to evaluate the effect of tobacco on detoxification enzymes, esterases, glutathione S-transferases (GST) and cytochrome P-450 monooxygenases (MO) were determined in both selected aphid genotypes after 12, 24, 36, 48 and 72 h of rearing on tobacco and pepper.
