Defoliates mature jack pine. The jack pine budworm, native to North America, has a range that coincides almost exactly with jack pine, its preferred host. Root borers, root feeders, shoot and stem borers, leaf feeders, needle miners, and sucking insects affect the survival and growth of seedlings.
Many other insects feed on jack pine Size: KB. Radial growth suppressions caused by jack pine budworm defoliation were identified using a host and non-host comparison and calibrated against historical outbreak records.
Five periods of major growth suppression were identified (–, –, –, – and –) that matched historical jack pine budworm by: 8. Jack pine budworm defoliation is part of the natural disturbance regime, and our goal was to increase our scientific understanding of this ecological process.
Study Area and Jack Pine Budworm Ecology. The Pine Barrens region of northwest Wisconsin covers aboutha and is characterized by sandy soils formed on a glacial outwash by: ack pine budworm, Choristoneura pinus Freeman, is a destructive insect that attacks pines in central and northwestern Ontario, Manitoba and Saskatchewan and in the Great Lakes region.
Severe outbreaks seriously affect the growth and quality of vast areas of pine. This insect prefers jack pine, but red pine. two fire-dependent ecosystems for which jack pine (Pinus banksiana Lamb.) is the canopy dominant: jack pine forest, and jack pine savanna.
This contrast will illustrate that the restoration goals of prescribed burning will differ even between ecosystems with similar canopy composition.
The annual Forest Insect and Disease Survey reports of the Canadian Forestry Service were used to develop a jack pine budworm (Choristoneurapinus Freeman) defoliation severity index for a year region covered was the western half of the host's (Pinusbanksiana Lamb.) interpretation of this record permitted the construction of an annual time series of the total area.
Batzer HO, Jennings DT () Numerical analysis of a jack pine budworm outbreak in various densities of jack pine. Environ Entomol 9: – Google Scholar Beaufait WR () Some effects of high temperatures on the cones and seeds of jack pine. The jack pine budworm (Choristoneura pinus pinus) infestation that occurred in northeastern Ontario from to was assessed for its impact on the province's jack pine (Pinus banksiana) resource.
Jack pine stands were monitored to provide a basis for identifying impact estimators to be applied to defoliation maps and timber inventory data. sent volume is found in the jack pine 6 forest type, Use of two Bt formulations for suppression of jack pine budworm the remainder is in other forest types of which jack pine is a component.
As ofnet volume of jack pine sawtimber in the Lake States was billion board feet: 55 percent in Minnesota, 28 percent in Wisconsin, and 17 percent in Michigan. Production In42 million board feet.
Jack Pine is difficult to tell apart from some of the lighter yellow pines whose native ranges are farther west, such as Lodgepole Pine and Ponderosa Pine. Generally, dimpling on flatsawn surfaces will appear more subdued and less common in Jack Pine than in Lodgepole Pine.
Although Jack Pine is technically classified as a yellow (hard) pine. Use of two Bt formulations for suppression of jack pine budworm, Nebraska National Forest, / Comparison of two successive laboratory generations reared on synthetic diet and on frozen.
Annual jack-pine budworm, Choristoneura pinus pinus Freeman, population samples and weather records from Douglas County, Wisconsin during. Abstract: Jack pine budworm, Choristoneura pinus pinus Freeman, is an important defoliator of jack pine, Pinus banksiana Lamb., and to a lesser extent on red pine, P.
resinosa Ait., in the Great Lakes region and Canada. Extensive top kill is common during outbreaks, but tree mortality is rare unless infestations coincide with periods of drought.

Jack Pine Budworm. The jack pine budworm component was modelled by generat ing two stochastic variables: (I) the time interval between budworm outbreaks.
and (2) the effect of budworm defoliation on jack pine growth. Stochastic variables are defined by a probability distribution and, therefore, are not constants. They were used to determine the. Stand-level mortality and top kill from a – jack pine budworm (Choristoneurapinuspinus Freeman) outbreak were surveyed annually in the Raco Plains area of the Hiawatha National Forest in Michigan's Upper Peninsula from to Defoliation was visually estimated and percentage of trees killed or top killed was determined in stands.
Data from jack pine budworm Choristoneura pinus pinus outbreaks in to yr-old jack pine (Pinus banksiana) stands in northern Ontario were used to examine the relation between the relative frequency of staminate shoots and the mortality of early- and late-larval jack pine budworm.
Although there was some indication that early-instar budworm may be more successful at establishing feeding. Jack pine responses varied greatly and depended on whether seedlings were treated with single or multiple organisms, and their order of damage.

These will help to disrupt the dispersal of the budworm. Even-aged stands of jack pine should not exceed 20 to 40 acres. Do not break up the jack pine stands with other species of pine. During a budworm outbreak, other.
The jack pine TMP used in this work was produced using our Metso CD pilot-scale unit. The refining was performed in two stages.
The primary stage was carried out at °C with a discharge consistency of about 24 %. The primary pulp, having a. A jack pine budworm is a pest. It is most damaging to pine trees. Jack pine budworms eat the needles of pine strands.
It is native to North America. The jack pine budworm occurs on a regular cycle, but the budworm has only one generation each year. Jack pine budworm eggs typically hatch within days.
The pine wood nematode Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle is the causal agent of pine wilt disease. We evaluated the efficacy of emamectin benzoate (EB) for preventing wilt disease in the field and its effect on the vector Monochamus galloprovincialis (Olivier) (Coleoptera: Cerambycidae).
Four experimental plots were delimited in a maritime pine (Pinus pinaster Aiton) forest. Jack pine (Pinus banksiana) is an important species in the northeastern and northcentral United States and Canada for timber and wildlife habitat, especially the endangered Kirtland's warbler.
The management of jack pine typically involves a clear-cut every ~50 years and a seed-bed preparation treatment to enhance natural regeneration. Two such types of treatment include dragging a chain.

Use correct per-acre rate, and reduce the acreage treated. (3 foot bands on 9 foot centers treats only 1/3 ofthe field.) Best to apply before weeds have grown over the pines.
Drought-stressed seedlings more likely to be injured. Surfactants could increase chance ofinjury to pines: use cautiously or avoid.

Pine straw, the uppermost forest floor layer of undecayed needles, is raked, baled, and sold as landscaping mulch in the southeastern U.S., and has become a valuable forest commodity. Annual pine straw income to forest landowners in Georgia has ranged from $ million in to $81 million in.
