Association of the pine‐top weevil with Endocronartium pini on Scots pine

It has been suggested that the pine-top weevil (Pissodes piniphilus) could be a vector of resin-top disease caused by Endocronartium pini. The association of this weevil with trees and stands infected with the fungus was studied. The number of pupal chambers around cankers and in trapping bolts indicated an association. Mobility studies with flight traps and sticky rings, however, gave inconclusive results as to the possible role of the weevil as vector of the disease.
