Issued also in French under title: Un cadre conceptuel pour l'intervention précoce contre la tordeuse des bourgeons de l'épinette : peut-on arrêter les épidémies? "The spruce budworm is a native forest insect that inhabits the spruce-fir forests of northeastern North America. Outbreaks of this insect occur every 30 to 40 years. During this cycle, populations range from being very low (endemic) to very high (epidemic). If left unmanaged, these outbreaks can result in significant growth reduction and mortality of spruce and balsam fir trees"--Page [1]. Spruce budworm Control Quebec.
