Seasonal infectivity of Cacopsylla pruni, vector of European stone fruit yellows phytoplasma
Annals of Applied Biology, 2004SummaryEpidemiology of European stone fruit yellows was studied by focussing on the life cycle and transmission characteristics of the vector Cacopsyllapruni. The proportion of both phytoplasma positive and inoculative insects was determined for the first C. pruni adults back colonising the stone fruit trees in spring and for the new generations of the

AbstractIn the Campania region of southern Italy, peach trees showing vein enlargement and decline symptoms, as well as apricot and Japanese plum trees showing symptoms similar to that of apricot chlorotic leaf roll and plum leptonecrosis, respectively, were examined for phytoplasma infection using PCR technology.

A study was carried out on the transmission parameters of the European stone fruit yellows phytoplasma by the vector Cacopsylla pruni. In the greenhouse, using groups of psyllids, the minimum acquisition period was 2–4 days, the minimum latent period 2–3 weeks and the minimum inoculation period 1–2 days.

Role of wild Prunus species in the epidemiology of European stone fruit yellows
Plant Pathology, 2002Several uncultivated trees of the species Prunus spinosa , P. cerasifera and P. domestica , sampled both adjacent to European stone fruit yellows (ESFY)‐infected orchards and in isolation from cultivated stone ...

The aim of the study was to assess the role of blackthorn (Prunus spinosa) in the epidemiological cycle of ESFY and to search if an epidemiological cycle may exist independently of stone fruit orchards. A typical blackthorn hedge was chosen in an area free of fruit orchards. A sample of 58 plants was tested for ESFY and 2 plants were detected infected.

European stone fruit yellows (ESFY) is caused by a phytoplasma and transmitted by Cacopsylla pruni. As it is becoming a major threat in Europe for Prunus orchards, we need more knowledge on many fundamental epidemiological processes of this disease.

Prunus species are prone to infections by viruses and phytoplasmas, against which no effective cure exists for already infected plants in the field. Phytoplasmas infecting fruit trees can cause severe symptoms and are considered as quarantine organisms in Europe and North America.
