Extract

In a previous report (Jansson and Smilowitz 1985), several life statistics of Myzus persicae (Sulzer) were compared on upper and lower leaves of three potato cultivars (Solanum tuberosum tuberosum cvs. Katahdin, Norchip, and Superior). In general, life statistics were similar (p > 0.05) between cultivars. However, certain life statistics (fecundity and intrinsic rate of increase) consistently were greater (p < 0.05) on lower leaves than on upper leaves of each cultivar. In the previous study, we did not include data on age-specific survival or the relationship between fecundity and longevity to support the premise that the population dynamics of M. persicae on potato are related to the physiological age of leaves (i.e. nutritional quality of leaves) (see Jansson and Smilowitz 1985). This information would be useful for developing a model describing the population dynamics of M. persicae. For this reason, we present here data on age-specific survival and the relationship between fecundity and longevity of M. persicae on upper and lower leaves of three Dotato cultivars.
