The Douglas-fir tussock moth is a serious defoliator [,,], as are the western spruce budworm [,], the New Mexico fir looper, and the white fir needle miner. White fir seedlings and saplings lack chemical defenses against, and tend to be killed by . Full text of "Pesticides documentation bulletin" See other formats.

Haynes (page images at HathiTrust). For example, in mixed stands containing not only spruce and fir but also various other tree species not fed upon by the budworm, such as aspen, birch and pine, damage was slight to spruce and fir growing beneath or in the shade of the non-host trees. In contrast, damage was severe to spruce and fir growing in the open, though only a few yards away.
A current partial defoliation of young fir throughout the east half of the forest looked very serious for the future of watershed cover. Entomologists identified the trouble as a combined attack of a needle miner and a leaf disease. The epidemic had been spreading rapidly for three or four years and was expected to prove fatal if it persisted. Firs and spruce have only one needle (no ‘bundles’) but the shape of that needle can differ by tree species. SPRUCES (native): FIRS (native): Subalpine fir. The short ("), single, flat needles also have rounded tips but are thick at their base (vs. white fir).

This book was published by. On moist to moist-wet sites where balsam fir is mixed with white spruce, spruce is preferred because of its higher timber value, longer life, and greater tolerance to spruce budworm defoliation. If a mature fir stand has more than well-distributed white spruce that are three feet or taller an acre, clearcut the stand to release the spruce.

() also reported variable spruce budworm growth among balsam fir, lowland and upland black spruce, and white spruce, which was related to foliar N, Fe, and K.
Likewise, Schmitt et al. () found that budworm pupae and moths from balsam fir trees were significantly heavier than those from red spruce, and that weight was correlated overall Cited by: Abstract. Throughout this book I have attempted to develop a general framework for understanding and managing forest insect pest populations—general in the sense that the principles and methods should be applicable to any insect pest problem anywhere in the by: 1.

The spruce budworm (Choristoneura fumiferana) is one of the most destructive native insects in the northern spruce and fir forests of the Eastern United States and Canada. Periodic outbreaks of the spruce bud-worm are a part of the natural cycle of events associated with the maturing of balsam fir.
