'Candidatus Phytoplasmas mali': identification of potential insect vectors in Spanish apple orchards

摘要

Samplings realized in apple plots of different geographical areas of Spain indicated the presence of the two species of Cacopsylla reported as vectors of the apple proliferation disease. The population evolution of Cacopsylla picta and C. melanoneura was followed during two years in the two regions of Spain where these species were identified. The population showed two peaks, one for adults re-immigrants, which in the two years occurred in early April and other for new generations between June and July.
