Abstract

The species composition of jumping plant-lice, especially Cacopsylla pruni as a vector of ‘Candidatus Phytoplasma prunorum’, was researched on stone fruit trees in 53 locations, mainly in Central Poland. Twelve species were found to belong to the families Psyllidae, Aphalaridae and Triozidae. C. pruni which made up 59.9% of the collected specimens was noted in eight locations in plum orchards and in two locations in cherry orchards. Only three locations were found to have specimens of C. pruni which were infected by ‘Ca. Ph. prunorum’, namely on plum trees in the Lesser Poland Province and plum and mirabelle plum trees in the Masoovian Province. In the latter location, specimens of C. pruni infected with ‘Ca. Phytoplasma asteris’ were also caught in mirabelle plum trees. We can conclude that at this moment C. pruni is not a significant threat to Polish stone fruit orchards and its importance in the possible spread of phytoplasma causing European stone fruit yellows is low.

Key words: ‘Candidatus Phytoplasma asteris’, European stone fruit yellows.
