This study examined the life history traits of Aphis coronillae Ferrari (Hemiptera: Aphididae) clones collected in Utsunomiya City, Tochigi Prefecture, eastern Japan. Results showed that the collected clones are classifiable into two life cycle forms: holocyclic and anholocyclic. No significant difference in nymphal development, fecundity, or adult longevity was observed between holocyclic and anholocyclic clones. Results also indicated that photoperiod and temperature affect sexual morph production in holocyclic clones.
