Les pratiques sylvicoles sont aujourd\u2019hui remises en causes de par l\u2019\u00e9volution des attentes soci\u00e9tales vis-\u00e0-vis de la for\u00eat et la menace du changement climatique. Dans cette \u00e9tude sont compar\u00e9es le r\u00e9gime de monoculture avec renouvellement par coupe rase \u2013 r\u00e9gime tr\u00e8s couramment pratiqu\u00e9 en Europe et Am\u00e9rique du Nord durant ces derni\u00e8res d\u00e9cennies \u2013 avec 3 m\u00e9thodes de gestion foresti\u00e8re alternatives : la sylviculture \u00e0 courte rotation, la sylviculture foresti\u00e8re m\u00e9lang\u00e9e et la sylviculture \u00e0 couvert continu. Cette \u00e9tude \u00e9value comment ces m\u00e9thodes alternatives affectent le contr\u00f4le naturel des insectes forestiers (parasites de la r\u00e9g\u00e9n\u00e9ration, insectes d\u00e9foliateurs et scolytes). Un accent particulier a \u00e9t\u00e9 port\u00e9 sur l\u2019effet de la gestion foresti\u00e8re sur la lutte naturelle de ces parasites.
\nLes auteurs avancent que le recours \u00e0 une des m\u00e9thodes alternatives de gestion foresti\u00e8re aura pour effet, dans la plupart des cas, de diminuer la qualit\u00e9 et la quantit\u00e9 de la ressource disponible et d\u2019augmenter la pression naturelle des pr\u00e9dateurs sur les parasites forestiers.
\nAlors que l\u2019augmentation des populations de parasites causant la plupart des d\u00e9g\u00e2ts dans les for\u00eats g\u00e9r\u00e9es d\u2019Europe (scolytes, etc.) est principalement limit\u00e9e par la quantit\u00e9 de mat\u00e9riel v\u00e9g\u00e9tal convenant \u00e0 leur reproduction, le changement de gestion foresti\u00e8re pourrait permettre de modifier les caract\u00e9ristiques des peuplements et favoriser activement les ennemis naturels de ces parasites. Cependant, il reste \u00e0 examiner dans quelles mesures de tels changements aboutiront \u00e0 la diminution des d\u00e9g\u00e2ts aux arbres m\u00eame si quelques preuves pointent d\u2019ores et d\u00e9j\u00e0 dans cette direction.
