Abstract: Apple orchards in four localities in southwestern Finland were surveyed in May 2009 and 2010 to monitor the occurrence of Cacopsylla picta (Förster) and C. melanoneura (Förster), vectors of apple proliferation phytoplasma. Both psyllid species were present in apple orchards, but C. picta prevailed. The number of individuals varied considerably in 2009-2010. The total number of captured overwintering Cacopsylla species from the same orchards was 395 in 2009 and 45 in 2010. Individuals of C. picta infected with `Candidatus Phytoplasma mali' were found from single orchards in Lohja and Parainen. In 2010 the incidence of `Ca. P. mali' in C. picta individuals collected from apples (Malus domestica) was 11.4%.
