“…Mechanical injuries during thinning and pruning operations create wounds that provide entry sites for many forest pathogens, such as cankers, stains and rot fungi (Bruhn et al, 2002;Chou and MacKenzie, 1988;Hessburg et al, 2001;Metzler, 1997;Rönnberg, 2000;Zolciak and Sierota, 1997). Several bark beetles such as Ips typographus (Vaupel et al, 1981) and Dendroctonus micans (Grégoire, 1988) and the stem borer Dioryctria sylvestrella (Jactel et al, 1996a; are attracted by resin odours released from injured stems after pruning or thinning, and then go on to attack living trees in the vicinity.…”

Abstract• This article synthesizes and reviews the available information on the effects of forestry practices on the occurrence of biotic and abiotic hazards, as well as on stand susceptibility to these damaging agents, concentrating on mammal herbivores, pest insects, pathogenic fungi, wind and fire.• The management operations examined are site selection, site preparation, stand composition, regeneration method, cleaning and weed control, thinning and pruning, and harvesting. For each of these operations we have examined how they influence the occurrence of biotic and abiotic damaging agents, the susceptibility of European forests, and describe the ecological processes that may explain these influences.• Overall, we find that the silvicultural operations that have the largest influence on both biotic and abiotic risks to European forest stands are closely related to species composition and the structure of the overstorey. Four main processes that drive the causal relationships between stand management and susceptibility have been identified: effect on local microclimate, provision of fuel and resources to biotic and abiotic hazards, enhancement of biological control by natural enemies and changes in individual tree physiology and development.• The review demonstrates an opportunity to develop silvicultural methods that achieve forest management objectives at the same time as minimising biotic and abiotic risks. Mots-clés :sylviculture / peuplement / occurrence / sensibilité / Résumé -Influences de la sylviculture sur le risque de dégâts biotiques et abiotiques dans les peuplements forestiers.• Cette revue bibliographique s'intéresse aux effets de la sylviculture sur la sensibilité des peuplements forestiers aux principaux agents de dégâts biotiques et abiotiques que sont les mammifères herbivores, les insectes ravageurs, les champignons pathogènes, le feu et les vents forts. * Corresponding author: herve.jactel@pierroton.inra.frArticle published by EDP Sciences Ann. For. Sci. 66 (2009) 701 H. Jactel et al.• Les pratiques forestières analysées sont la sélection et la préparation des sites de reboisement, la définition de la composition en essences et le choix du matériel génétique, les méthodes de régé-nération et d'entretien, les modalités d'éclaircie et d'élagage, le mode de récolte finale. L'influence de chacune de ces opérations sur l'occurrence des agents de dégâts biotiques et abiotiques et sur la sensibilité des peuplements est examinée ainsi que les processus écologiques sous-jacents.• Les opérations sylvicoles qui se révèlent les plus déterminantes pour la sensibilité des forêts en Europe sont celles qui affectent la composition et la structure de la strate arborée. Quatre principaux processus écologiques semblent expliquer la relation entre sylviculture et sensibilité des peuplements : la modification du micro-climat, l'apport de ressources ou de combustible aux agents de dégâts, l'amélioration du contrôle biologique par les ennemis naturels et l'altération de la physiologie et du développement des arb...

“…There is a general agreement that droughts tend to facilitate outbreaks of many bark beetles (Mattson & Haack, 1987;Abbott, 1993;Lorio, 1996). Most historical records of D. micans outbreaks in Eurasia are related to severe drought (GreÂ goire, 1988). In our study, all the plots in the study area were subjected to fairly similar climatic conditions which could translate into variable water stress according to the slope.…”

“…Sib-mating is a common rule: nearly 90% of females emerge from their brood system already fertilized (Vouland et al, 1984), and male beetles do not join females in their new galleries. Tolerance to spruce chemical defenses is extremely high (Everaerts et al, 1988), and successful establishment does not depend on mass-attack or tree mortality (GreÂ goire, 1988) as in other primary bark beetles (Wood, 1982). Each single female is thus capable of creating a new colony wherever she migrates.…”

“…D. micans causes significant damage at the range of its geographical distribution, which has considerably expanded in Europe over the last 100 years. The population dynamics of the insect at this scale are marked by the following successive events: invasion of an uncolonized areas, population outbreaks and stabilization of the population at an endemic level (GreÂ goire, 1988). The specific predator Rhizophagus grandis Gyll.…”

1 Spatial pattern in abundance of Dendroctonus micans was studied in a 600-ha spruce stand in the Massif Central (LozeÁ re, France). The proportion of trees attacked was measured in 38 plots and these data were used to estimate spatial pattern of attack density in the stand and to identify a transect of decreasing attack density (80% to 30%) over less than 1000 m. 2 Spatial variation in attack density was analysed in relation to (i) data on site and stand characteristics (altitude, slope, tree density, tree average height, yield class and average age) collected from 63 points in the stand and (ii) the releases of the predator Rhizophagus grandis (localization and number of beetles released). 3 The proportion of attacked trees was analysed using geostatistics and showed a strong spatial structure reflecting the spatial scale of interaction of D. micans with its environment. The spatial structure was modelled in order to estimate the spatial distribution of attack density at unsampled locations. 4 A linear model relating interpolated attack density to the number of predators released 6±10 years before the survey in a 300-m radius and to the average slope over a 250-m radius explained 67% of the observed variability. Spatial autocorrelation was taken into account in a spatial regression model.

Anahtar kelimeler:Kabukböceği spesifik predatör böcek zararı Keywords:Bark beetle specific predator pest damage Özet Bu çalışmada Dendroctonus micans (Kugelann) (Coleoptera: Curculionidae)'ın Artvin doğu ladini (Picea orientalis (L.) Link.) ormanlarındaki güncel populasyonu ve spesifik predatörü Rhizophagus grandis Gyllenhal (Coleoptera: Monotomidae)'in böceğin galerilerini istila durumu araştırılmıştır. Arazi çalışmalarında, toplam 30 örnekleme alanı ve 20 transektte çalışılmıştır. Örnekleme alanları 30 × 10 m boyutlarında ve transektler de 50 m uzunluğundadır. Günümüzde, D. micans'ın Artvin ladin ormanlarında "çok düşük istila" oranına sahip olduğu ve böceğin ağaçlardaki istila yüzdesinin 2000'li yılların başına oranla 4.1 kat azaldığı tespit edilmiştir. Meşcere kenarında bulunan ağaçlar meşcere içine göre daha fazla böcek zararına uğramıştır. D. micans'ın larva galerilerinin tamamında R. grandis tespit edilmiştir. Böceğin ormanlardaki zararı düşük seviyede olduğunda da R. grandis'in avının larva galerine yerleşebildiği tespit edilmiştir. AbstractIn this study, current population of Dendroctonus micans (Kugelann) (Coleoptera: Curculionidae), and colonization status of its specific predator Rhizophagus grandis Gyllenhal (Coleoptera: Monotomidae) in oriental spruce (Picea orientalis (L.) Link.) forests of Artvin were investigated. Field works were conducted in a total of 30 sampling plots and along 20 transects. Sampling plots were 30 × 10 m in size and transects 50 m long. Presently, D. micans has a "very low infestation" rate in Artvin spruce forests and D. micans infestation rate is 4.1 times lower than the early 2000s. The trees at the stands edges were attacked more than trees in stand closure. All the larval galleries of D. micans were colonized by R. grandis. R. grandis could colonize larval galleries of its prey even in endemic conditions.
