Shoot Damage

Insect damage to jack pine shoots (Pinus banksiana Lamb.) in the Lake Nipigon region of Ontario was first reported by Thomas and Lindquist (1956). Since then, a study of insects infesting jack pine shoots has shown that a bark beetle, Conophthorus sp., has been chiefly responsible for shoot damage. A secondary borer, Cimberis elongatus (Lec.), was usually associated with the bark beetle, and because little has been published on the biology of any of the anthribids, the general life history of C. elongatus is outlined here.

AbstractPseudips mexicanus (Hopkins) is a secondary bark beetle native to western North and Central America that attacks most species of pine (Pinus L. (Pinaceae)) within its range. A pair of life-history studies examined P. mexicanus in other host species, but until now, no work has been conducted on lodgepole pine (Pinus contorta Douglas ex Louden var. latifolia Engelm. ex S. Watson). Pseudips mexicanus in lodgepole pine was found to be polygynous. Galleries were shorter, offspring smaller, and the eggs laid per niche and the potential progeny fewer than in populations from California and Guatemala. Development from the time of female attack to emergence of adult offspring took less than 50 days at 26.5 °C, and the accumulated heat required to complete the life cycle was determined to be 889.2 degree days above 8.5 °C, indicating that in the northern portion of its range P. mexicanus is univoltine. Determination of these life-history traits will facilitate study of interactions between P. mexicanus and other bark beetle associates in lodgepole pine.

Significant Damage

Leconte's sawfly or the red-headed pine sawfly (Neodiprion lecontei Fitch) is a common insect attacking pines in Ontario. Plantations red pine are almost invariably attacked from the time the trees have reached two to four feet in height. Periodically epidemic populations cause significant damage. The life history and habits of the species have heen described by Middleton (2) who states that this insect attacks practically all species of pine as bell as larch. Schaffner (3) also indicates that the larvae feed on a wide variety of pine and occasionally on other conifers. Red pine (Pinus resinosa Ait.) is undoubtedly the usual host, although in Ontario jack pine (Pinus banksiana Lamb.) is sometimes attacked. In 1946 evidence was secured to show that jack pine needles may be selected for oviposition even in an area where red pine foliage is plentiful. (Figure 1).

Insect Survey

The occurrence of midges on jack pine, Pinus banksiana Lamb., in Manitoba has been reported by Lejeune (4), Barker and Wong (1), and Prentice and Hildahl (5, 6). The Forest Insect Survey also reported a species of Retinodiplosis on jack pine in Ontario, and Barnes (2) suggested that this may have been R. resinicola (Osten Sacken). This name was also provisionally assigned to a species found near Stead, Manitoba, in 1956 (7). Vockeroth (8) now shows that Retinodiplosis Kieffer is a synonym of Cecidomyia Meigen, which is represented by at least two species on jack pine in Manitoba and Saskatchewan. These are C. reeksi and C. banksianae. The former is the more common and undoubtedly was the species most frequently represented in the early reports of pine midges in Manitoba.

Shoot Damage

Abstract The exotic pine shoot beetle, Tomicus piniperda [L.] (Coleoptera: Scolytidae) is a Eurasian pest of pines that was first discovered in North America in 1992 near Cleveland, Ohio. It has since been found in at least 72 counties in Michigan, 285 additional counties in 11 other north central and eastern states, and the provinces of Ontario and Quebec. We counted injured shoots along linear transects in ten stands of Scotch (Pinus sylvestris L.), red (Pinus resinosa Aiton), and jack pine (Pinus banksiana Lambert) in lower Michigan (30 stands total) to estimate the frequency of shoot damage attributable to pine shoot beetle, other shoot-feeding insects, weather, and other damaging agents from 1997 to 1999. Fifteen of the stands were located in southwestern counties where pine shoot beetle has been established for at least 8 to 10 yr. The other 15 stands were in northern counties where pine shoot beetle establishment is more recent. In the southwestern stands, pine shoot beetle killed significantly more shoots in Scotch pine stands than in red or jack pine stands, and injured more shoots in Scotch pine stands than all other insects combined. Two of these Scotch pine stands were near an area with an abundance of Scotch pine brood material available to parent beetles. Damage in these two stands averaged roughly 10 to 12 shoots per m2 in 1998 and 1999, compared with 0.6 to 1.6 shoots per m2 in other Scotch pine stands, and less than 0.2 shoots per m2 in nearby red or jack pine stands. Pine shoot beetle was at very low or undetectable levels in northern stands in all years. Shoots injured by three other shoot-feeding insects were occasionally encountered, most often in red pine stands, but caused an insignificant amount of damage. With the exception of the southwestern Scotch pine stands, most of the shoot damage, particularly in northern jack pine stands, was attributable to squirrels or abiotic factors such as wind, ice or snow.

Probable Origin

Interpretation of genetic variation associated with geographic origin must take into account the evolution and migratory history of the species being-studied. A literature survey was made to determine the probable origin of jack pine (pinus banksiana) and its migration from glacial refugia following the Wisconsin glacial maximum. Jack pine and contorta pine (Pinus contorta) became differentiated following cooling of the climate and crustal uplift in western North America in the late Tertiary. Modern hybrid swarms and introgression of jack pine and lodgepole pine (Pinus contorta var. lalifolia) east of the Rocky Mountains are of recent origin, dating from late post-glacial migration from the east and west respectively. Geological and paleobotanical evidence, particularly from fossil pollen depositions, indicate that jack pine survived glaciation in an extensive refugium centered on the Appalachian Highlands of eastern North America, and not in additional refugia south or west of the Great Lakes. This conclusion is consistent with the clinal pattern of geographic variation evident from genecological studies of the species.

A New Species

Aphids of the species herein described as new can be readily distinguished from all other species in the genus Cinara by the unusual length of the unguis. The feeding site is also characteristic; this is the only species in the genus known to feed on the roots of Pinus banksiana.The species was first collected in 1956 at Lac La Ronge, Saskatchewan, by B. B. McLeod, of the Winnipeg Laboratory. In 1957 it was found by the authors at Cedar Lake, thirty miles north of Vermilion Bay, Ontario, where observations on the life history of the species were carried out.

Arceuthobium Americanum

The purpose of this study was to test the hypothesis that infection of jack pine (Pinus banksiana Lamb.) by jack pine dwarf mistletoe (Arceuthobium americanum Nutt. ex Engelm.) increases with increasing tree age and decreases with increasing tissue age. One-, 2-, and 3-year-old tissues of 3-, 5-, and 7- year-old jack pines and 1-, 4- and 8-year-old tissues of 12-, 17-, and 22-year-old jack pines in Belair Provincial Forest were inoculated with seed of A. americanum in September of 1992 (year 1) and 1993 (year 2). Overwinter and postwinter seed removal, fungal and insect damage, and infection success were monitored from the time of inoculation to harvesting of inoculated branches. In years 1 and 2, overwinter seed displacement was 12.2 and 30.6%, while postwinter loss was 28.8 and 22.2%, respectively. Seed germination ranged from 14.3 to 38.1% and from 3.1 to 17.5%, respectively, in years 1 and 2. Infection success varied from 2.0 to 35.0% (year 1) and from 0.0 to 13.0% (year 2). Lower mean daily temperatures in January and February (p < 0.001) were hypothesized to have killed more seeds and thereby reduced infection success in year 2. Infection success did not increase with increasing tree age (year 1: p = 0.188; year 2: p = 0.807) in either year of the study. Infection success increased with increasing tissue age in year 1 (p < 0.001) but not in year 2 (p = 0.358). We rejected the hypotheses that susceptibility to infection by A. americanum increases with increasing tree age or decreases with increasing tissue age of jack pine. Infection success appears to be primarily dependent upon seed displacement caused by wind, snow, or rain.Key words: jack pine, dwarf mistletoe, infectivity, juvenile resistance, seed displacement.
