“…It has been observed that shade alters the temperature and the humidity level to one that is unfavorable for oviposition (Sullivan, 1961). In addition, the decrease in leader diameter and bark thickness caused by shading further negatively influences weevil activity (Sullivan, 1961;Wilkinson, 1983;Lavallé e et al, 2001). The tradeoff is a significant reduction in productivity.…”

“…The manager will be faced to the following options: i) creating larger gaps (e.g., 2H, H = stand height) and planning release treatments during the first years after gap creation; or ii) creating smaller gaps, which require more initial resources to carry out in the field but potentially less need for release afterwards. We must also keep in mind that it can be advantageous to grow eastern white pine under partial cover during the period of its life where the species is most susceptible to the white pine weevil (Lavallée et al 2001). For personal use only.…”

In mixed tolerant hardwood -white pine stands of Southwestern Quebec, the effects of group selection cutting on eastern white pine (Pinus strobus L.), red oak (Quercus rubra L.), yellow birch (Betula alleghaniensis Britton) and paper birch (Betula papyrifera Marsh.) regeneration are compared to the currently used single-tree selection cutting. The experimental design, initiated in 1998, comprised three cover reduction treatments (circular gap (45 m, 1590 m 2 )), 25% and 35% single-tree selection cutting), two scarification treatments (scarified and non-scarified) and two seeding treatments for white pine (seeded and non-seeded). The effect of white pine seed predation was studied in the gaps and the adjacent understory, with exclosures for small mammals. After three years, scarification had a positive effect on white pine, yellow birch and paper birch regeneration but also on aspen (Populus spp.) and pin cherry (Prunus pensylvanica L.f.) in the three cover reduction treatments. Red oak regeneration was negatively affected by scarification. Shade-tolerant species (sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.)) tended to be less present in the regeneration gaps than in the single-tree selection cutting. Considering that white pine seed predation can be critical in mixed tolerant hardwood -white pine stands, a greater rate of seeding is recommended for direct seeding.Key words: group selection cutting, regeneration gap, single-tree selection cutting, tolerant hardwoods, eastern white pine, yellow birch, paper birch, red oak, scarification, direct seeding, regeneration, seed predation Dans les peuplements de feuillus tolérants et de pin blanc du sud-ouest du Québec, les effets du jardinage avec trouées sur la régénéra-tion du pin blanc de l'est (Pinus strobus L.), du chêne rouge (Quercus rubra L.), du bouleau jaune (Betula alleghaniensis Britton) et du bouleau à papier (Betula papyrifera Marsh.) sont comparés au jardinage par pied arbre conventionnel. Le dispositif expérimental, implanté en 1998, comprend trois traitements de réduction du couvert (trouée (45 m diamètre, 1590 m 2 ), jardinage par pied d'arbre 25% et 35%), deux traitements de scarifiage (scarifié et non scarifié) et deux traitements d'ensemencement artificiel pour le pin blanc (ensemencé et non ensemencé). Les effets de la prédation des semences de pin blanc ont été étudiés dans les trouées et leur sous-bois adjacent, à l'aide d'exclos pour petits mammifères. Après trois ans, le scarifiage avait un effet positif sur la régénération de pin blanc, de bouleau jaune et de bouleau à papier mais aussi sur la régénération du peuplier et du cerisier de Pennsylvanie et ce, dans les trois traitements de réduction du couvert. La régénération du chêne rouge a été affectée négativement par le scarifiage. Les espèces tolérantes à l'ombre (érable à sucre (Acer saccharum Marsh.) et hêtre à grandes feuilles (Fagus grandifolia Ehrh.)) tendaient à être moins présentes dans les trouées de régénération que dans le jardinage par pied d'ar...

“…Integrated pest management is an ecological approach to pest control with the objective of using a combination of various tactics to reduce damage rather than to eliminate the pest. An effective IPM system could include the following components: use of planting stock with genetic resistance to the pest insect and tactics that reduce damage based on silviculture, such as shade conservation or increasing plantation density (Alfaro et al 1995, Lavallée et al 2001). Integrated pest management aims at reducing the loss of productivity of a site by optimising the selection of the appropriate combination of control methods that lead to a profitable crop.…”

Abstract-A number of insect species in a variety of families and orders damage early regenerating forests. Successful management of pests of regenerating forests requires detailed information on the natural history of the damaging organism, including the factors that increase risk, and a careful assessment of the risk mitigation options. Decision support systems, in the form of stand models capable of incorporating pest management options are required to guide decisions in terms of the expected yields under various pest management scenarios. In this paper we review research to date on the natural history and damage of the most important insect pests of regenerating forests in Canada and propose a framework for risk assessment. Canadian scientists have been active contributors to the research that advanced this field, from the early descriptive studies, to the development of practical tools to assist industry in managing pests of young forests.
