Spirea aphid

Aphis spiraecola Patch

Hemiptera: Sternorrhyncha: Aphididae

The eggs are oval and shiny black. The adults and nymphs are olive-green with brown-black legs (A), antennae, and cornicles. They live in colonies.

  • Damage

    Attacks apple and pear. This aphid causes the curling of young leaves (B), reduces the growth of infested shoots and excretes honeydew on leaves and fruit that favors the development of sooty mold.


    Protect natural predators by the use of selective insecticides. Monitor colonies on growing shoots; application of selective insecticide may occasionally be necessary if high percentage of shoots have active aphid colonies (can simultaneously be used against leafhoppers and leafminers).
