Sexual morph production by two regional biotypes of Myzus persicae (Homoptera: Aphididae) in relation to photoperiod
Environmental Entomology 19 (1), 32-35
Abstract: A biotype of the green peach aphid, Myzus persicae (Sulzer), from Yakima, Wash. (46°34'N) produced gynoparae and males in response to daily scotophases that were 1.0-1.5 h shorter than those needed to induce the production of these morphs by a biotype of M. persicae derived from a more southern latitude (40°N) in Spain. Predictions regarding the production of these morphs under fall conditions in their regions of origin are consistent with field observations in these regions.
