Rhyacionia buoliana: galls on Pinus nigra

Pinus nigra, Velsen, lg Velserbeek; to judge by the branching pattern this sapling has survived infestations in earlier years.


In autumn the larva hollows a bud, then hibernates, then bores in a developing shoot until summer. Damaged shoots generally die off, but when a strong shoot is involved, the leading shoot in particlar, it may continue growing, resulting in a deformed, commercially uselsess, stem.


Pinaceae, monophagous (?)

Pinus contorta, halepensis, jeffreyi, mugo, nigra, pinea, pinaster, ponderosa, radiata, sylvestris.

Also mentioned from Abies alba, but probably only rarely on that plant.


Evetria buoliana.
