Host Associations

  • Prunus species (plum, cherry, peach) - T. prunicola
  • Quercus (oak) - T. quercus
  • Malus (apple) - T. pomaria, T. froggatti
  • Anagras epos - of T. pomaria
  • Anagrus armatus - of T. froggatti

Life Cycle

patterns vary by . T. prunicola and T. quercus: one per year, overwinter on twigs, hatch in spring (April-May), nymphal development through five instars, emerge mid-summer (July-August) and persist until fall. T. pomaria: two generations per year in Ontario, winter eggs hatch in May, first-generation adults present June-July, summer eggs deposited in leaf midribs, second-generation adults mature August-September. T. froggatti: two generations with possible partial third in New Zealand apple orchards.

Behavior

of some migrate to herbaceous vegetation when trees become unsuitable. are laid in concealed locations: in bark crevices for eggs, or in leaf and petioles for summer eggs. Strong jumping ability typical of leafhoppers.

Ecological Role

Herbivore; phloem feeder on deciduous trees. Some are agricultural pests of fruit trees. Serves as for in the Anagrus.

Human Relevance

Several are recognized pests of cultivated fruit trees. T. pomaria (white apple leafhopper) is a documented pest of apple in Canada and the United States. T. prunicola affects stone fruits (plum, cherry, peach). T. froggatti is a pest of apple in New Zealand.
