Some aphids will appear as white cottony growths on the bark. Others appear as typical aphid infestations. All types produce honeydew which may support sooty mold. Use Orthene, malathion, or Diazinon when aphids are first seen.
European pine shoot moth causes young shoots to fall over.
Infested shoots may exude resin. The insects can be found in the shoots during May. Use Diazinon or malathion when caterpillars are moving from overwintering sites to new shoots. This occurs in mid to late April or when needle growth is about half developed. A repeat application in 10 days is needed. Bark beetles bore into trunks making small holes scattered up and down the trunk.
