Pityophthorus juglandis(PITOJU)

Hosts

Categories have been assigned by the EPPO Secretariat on the basis of available data at the time of entry. They correspond to an evaluation of the biological importance of the host plant for the pest concerned, together with the economic importance of this plant for the EPPO region. These categories do not reflect the complexity of the associations that may exist between a host plant and a pest, nor result from exhaustive literature reviews. Further explanation of categories is available in the guide.
