Genetic variation in all-or-none life-history traits of the lacewing Chrysoperla carnea


, : Genetic variation in all-or-none life-history traits of the lacewing Chrysoperla carnea. Canadian Journal of Zoology, 647: 1542-1544

Aestival reproduction varies quantitatively within many western North American populations of the Chrysoperla carnea species complex; during the summer, individuals either reproduce or enter reproductive diapause. The expression of this all-or-none phenotypic trait is determined by 2 ecophysiological response patterns: response to photoperiod and response to prey. These response patterns also vary qualitatively.
