LOSS OF TREE VIGOR AND ROLE OF BORING INSECTS IN RED PINE STANDS HEAVILY INFESTED BY THE PINE NEEDLE GALL MIDGE IN KOREA

Ten species of tree borers in 3 families were collected from bait logs and dead trees in red pine forests infested by the pine needle gall midge, Thecodiplosis _iaponensis. They are secondary pests and played a minor role in causing tree mortality in the stands studied. Red pine stands with about 14 kQ of cambial electrical resistance on an average in May were very vital ; those with over 21 kQ were in high mortality as a result of attacks by the pine gall midge.
