Distribution

Documented from the Azores (Flores, São Miguel, Terceira), former Yugoslavia, and Serbia. The has been studied from collected at the Chrysanthemum Germplasm Resource Preserving Centre, Beijing Forestry University, China.

Diet

Phloem sap feeder; , feeding exclusively on Chrysanthemum .

Host Associations

  • Chrysanthemum morifolium - primary Main cultivated ; laboratory studies use variety 'Jinglinqiuge'
  • Chrysanthemum spp. - -level specialization

Life Cycle

Parthenogenetic maintained in laboratory colonies. present: predominate under stable conditions, while aphids develop under high . Alate disperse for location, host recognition, and site selection.
