Abstract
The pea aphid, Acyrthosiphon pisum, has a complex life cycle that alternates seasonally between asexual and sexual reproduction. During the spring and summer months, A. pisum reproduces parthenogenetically, producing clonal daughters for 10 to 20 generations. Fall temperatures and photoperiods induce the production of sexual females and males, which mate to produce overwintering eggs that hatch into asexual females.
