The effects of different Charleston pepper cultivars on the demographic parameters and the antioxidant levels of Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae)

Host plant diversity causes differences in the biology and adaptation of insects. In this study, variations some biological properties adaptive antioxidative response Myzus persicae (Sulzer,1776) (Hemiptera: Aphididae) on five Charleston pepper, Capsicum annuum L. (Solanaceae) cultivars were investigated under laboratory conditions (25±1°C, 60±5% RH). The lowest intrinsic rate increase (r = 0.193 d-1) M. was estimated tested cohort fed with Kanyon cultivar, while highest 0.248 found Tufan cultivar. Safkan cultivar exhibited levels GST-CDNB EST-PNPA at 562.80 207.64 nmol/mg protein, respectively, whereas showed 317.04 132.14 respectively. Analysis life table parameters enzymatic/non-enzymatic antioxidant that among we tested, most preferred host by persicae, a less suitable host.
