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.

gall

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 particular, it may continue growing, resulting in a deformed, commercially useless, stem.

host plants

Pinaceae, monophagous (?)

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