Life cycles

Dioecious holocyclic.

Host plants

Primary hosts: Ribes (blackcurant, redcurrant).
Secondary hosts: Asteraceae: Sonchus (sowthistles), Lactuca (lettuce), Chicorium (chicory and endive).

Agronomic impact

The presence of H. lactucae on its primary host (Ribes) causes yellowing of leaves. In itself it causes little harm on its secondary host, however it can transmit the non-persistent lettuce mosaic virus (LMV).

Natural enemies

Colonies are often restricted if predators are (see photo above)
