| Summary: | The contents of glucosinolates and erucic acid clearly vary in <i>Brassica napus</i> seeds, but a few studies still focus on the effects of <i>B. napus</i> cultivars on the life table parameters of <i>Myzus persicae</i>. In this study, the life history parameters of <i>M. persicae</i> in six <i>B. napus</i> cultivars were examined at 25 ± 1 °C, 50 ± 10% RH, and a photoperiod of 14 h of light/10 h of dark under laboratory conditions. The results showed that significant differences exist in the life table parameters of <i>M. persicae</i> in six <i>B. napus</i> cultivars. The female fecundity, net reproductive rate, intrinsic rate of increase, finite rate of increase, and total longevity of <i>M. persicae</i> were higher in Xinong 18, Aiganyou 558, and Aiyouku 999. However, the intrinsic rate of increase in <i>M. persicae</i> was significantly lower in Zhongshuang 11 (r<sub>m</sub> = 0.28 ± 0.006) and Mianxinyou 78 (r<sub>m</sub> = 0.23 ± 0.007), suggesting the host-induced suppression of <i>M. persicae</i> population growth. Among all the cultivars mentioned above, Zhongshuang 11 and Mianxinyou 78 were recommended for planting for decreasing <i>M. persicae</i> population numbers. Additionally, more attention should be paid to Xinong 18, Aiyouku 999, and Aiganyou 558 to control <i>M. persicae</i> populations, and we conclude that <i>Brassica napus</i> cultivars affect the developmental duration and the population dynamics of <i>M. persicae</i>.
