The native balsam fir sawfly, Neodiprion abietis (Harris) (Hymenoptera: Diprionidae), occurs throughout Canada, Alaska, and the northern United States of America (Rose et al. 1994; Drooz 1985). This sawfly was originally described as Lophyrus abietis (Hymenoptera: Diprionidae) (Harris 1841), then transferred to the genus Diprion (Hymenoptera: Diprionidae) (MacGillivray 1916). Rohwer (1918) established the genus Neodiprion for Nearctic species of the genera Lophyrus and Diprion. Based on differences in size, color, and female genitalic characters between adults reared from the genera Abies, Picea, Pseudotsuga, and Tsuga (Pinaceae), Ross (1955) considered N. abietis as a complex. After a thorough morphological and physiological study, Knerer and Atwood (1972) concluded that there were five strains of N. abietis in North America: one western and four eastern.

AbstractThe beetle-hunting wasp, Cerceris fumipennis Say (Hymenoptera: Crabronidae), native to eastern North America, provisions its subterranean nest almost exclusively with adult metallic wood-boring beetles (Coleoptera: Buprestidae), including the destructive emerald ash borer (Agrilus planipennis Fairmaire, EAB). This wasp provides a unique opportunity to survey indigenous and nonindigenous buprestid diversity. We discuss the accessibility, sustainability, and productivity of C. fumipennis with respect to its application as a buprestid surveying and monitoring tool.

Far more investigations of the deterioration and utilization of the stems of trees killed following spruce budworm (Choristoneura fumiferana [Clem.]) defoliation have been, or are being, carried out during the current budworm outbreak in eastern and central North America than in all previous outbreaks combined. Unfortunately the results are dispersed in a wide variety of publications, some of which are relatively obscure and difficult to find. This report is an attempt to assist the forest manager faced with salvage decisions, by reviewing and summarizing current knowledge and by identifying some of the potentially useful literature. Key words: Spruce budworm, balsam fir, stem deterioration, sap rot, dead trees, salvage, utilization, pulp quality.

Abstract A description is provided for Nectria macrospora. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Abies balsamea and other species of Pinaceae. DISEASE: On Pinaceae; canker of balsam fir GEOGRAPHICAL DISTRIBUTION: North America: Canada (Quebec Province, British Columbia), USA (Oregon); Europe (Norway). TRANSMISSION: Ouellette found spread in a north westerly direction from the original island site. No evidence has been given for insect spread but this cannot be ruled out for this group of organisms.

New Information

Four separate investigations of decay in balsam fir (Abies balsamea (L.) Mill.) have been carried out in recent years by forest pathologists in Eastern North America. Early in these studies it became apparent that the existing ideas concerning the identity of the fungi responsible for decay in living balsam fir trees required considerable revision. Trunk rot was confirmed as being caused mainly by Stereum sanguinolentum Alb. and Schw. ex Fries; however, five fungi, headed by Corticium galactinum (Fries) Burt, were found associated with most of the white stringy butt rots, and two fungi, Coniophora puteana (Schum. ex Fries) Karst. and Polyporus balsameus Peck, were associated with most of the brown cubical butt rots. Hitherto Poria subacida (Peck) Sacc. and P. balsameus were believed to cause practically all white and brown butt rots, respectively, in this species. The effect of site on the decay of living balsam fir is discussed, as is the extent and kind of decay with which each of the nine predominant heart-rot fungi was found associated. A brief outline is presented concerning the fungi found associated with the deterioration of dead balsam fir.

Marginal stands of balsam fir ( Abies balsamea [L.] Mill.) and eastern white cedar ( Thuja occidentalis L.) are found north of their limits of continuous distribution in eastern North America. Regional-scale paleoecological studies have suggested that fir and cedar populations could have had larger extents in the past. This study aimed at verifying this hypothesis at the local scale. Wood charcoal fragments were collected from the soils of two marginal fir and cedar stands as well as from 15 sites in the surrounding forest matrix where the species are absent currently. Anatomical identification and radiocarbon-dating showed that fir was more extensive in the study area until about 680 cal. BP, representing up to 31% of the charcoal assemblages at sites where it is currently absent. The evidence is less conclusive for cedar, however, although some of the charcoal fragments from the matrix sites could have been either fir or cedar (undistinguishable). Most of the dated fir/cedar charcoal in the matrix were from the ‘Medieval Warm Period’ (ca. 1000 cal. BP), suggesting contraction may have occurred at that time. Marginal fir – and possibly cedar – stands are thus relics of once more extensive populations. Fire is likely the main factor having contributed to the contraction of the species’ distributions. Fir and cedar are now relegated to areas where fires are less frequent and severe, such as the shores of lakes and rivers.
