Description, Biology, Life Cycle, Damage, Common Names, Images

Adult: pale green with darker patches at the base of siphunculi (*) .

- A heteroecious species with foxglove (Digitalis purpurea, D. ambigua) as primary host and potato as secondary host.
- Widely distributed in regions with temperate climates, this species also occurs on many plants in subtropical regions. Several biotypes have been identified. This species is mostly common on the lower-most leaves of potato.

[R]Life Cycle
- In late spring, alatae (*) spread to glasshouse plants and crops protected by aeration canopies other than fine nets.

This species is an active vector of potato leaf roll virus (PLRV) and, being polyphagous, also transmits cucumber mosaic virus (CMV) to various cultivated plants and beet yellows virus (BYV) to beet.
