Performance of cabbage-reared Myzus persicae on different plant species.
(a) Developmental time (days for aphids to reach the adult stage). (b) Survival rate (percentage of aphids survived to the adult stage). (c) Adult weight (mg). (d) Fecundity (the number of offspring laid per adult). (e) Total longevity (total number of days aphids lived) Different letters above the bars indicate significant difference among different treatments (P < 0.05).
