Identifying Leafhopper Targets for Controlling Aster Yellows in Carrots and Celery [PDF]
Aster yellows phytoplasma (Candidatus Phytoplasma asteris) is a multi-host plant pathogen and is transmitted by at least 24 leafhopper species. Pathogen management is complex and requires a thorough understanding of vector dynamics.

INCUBATION PERIOD OF ASTER‐YELLOWS VIRUS
THE ASTER-YELLOWS VIRUS alternates in nature between plant and insect vector hosts. The multiplication of the virus in these two hosts has been demonstrated experimentally and it therefore seems justified to use the term incubation period in preference to latent period or delay of infectivity.
