Brown Spruce Longhorn Beetle Regulated Areas
To slow the spread of the Brown spruce longhorn beetle to new areas, the Canadian Food Inspection Agency (CFIA) uses measures to control the movement of potentially infested materials. Slowing the spread of the Brown spruce longhorn beetle will protect Canada's environment and forest resources. It also helps keep international markets open to the forest industry and nurseries in non-regulated parts of Ontario and Quebec and in the rest of Canada.

Aerial Survey Results
Lines indicate the approximate flight path flown during aerial survey of NB forests for pests, diseases, and abiotic disturbances. Flights are conducted during clear visibility conditions, typically towards the end of June or early July. Observations are timed to optimize visibility of spruce budworm feeding characterized by reddening of current year needles on spruce and fir as they dry out. Although budworm feeding is often the focus, all types of disturbance are recorded.Polygons indicate the disturbances observed during the aerial survey. Wherever possible, the cause of the damage is reported from the air and ground surveys are used to confirmed agent if the stand is accessible.

Spruce Budworm L2 Mapping
Spruce budworm is the most destructive, native defoliating insect in eastern Canada. When budworm populations reach outbreak levels, significant ecological and economic damage occurs (see www.healthyforestpartnership.ca for more details). In New Brunswick, budworm populations are tracked through numerous surveys annually. In the fall, the budworm hatch from eggs, crawl to a secure location on the branches of trees and spin a small web to protect them from the winter elements. They will stay in this location, dormant, throughout the winter and into the spring of the following year before emerging to feed on the new needles of spruce and fir branches.This life stage is known as the second larval stage or “L2” for short, and it is an ideal time to sample populations. The survey is significant task, and members of the Forest Health section are aided by regional GNB staff and forestry industry cooperators in collecting the nearly 2000 sample locations across the province. The branches from this survey are taken to Forest Health lab in Fredericton where they go through a “wash” that separates the tiny budworm from the branches. Their numbers are then counted and used to develop maps of spruce budworm populations.These populations are used by the Healthy Forest Partnership research program to develop early intervention strategies to avoid to impacts of outbreak populations./La tordeuse des bourgeons de l’épinette est l’insecte défoliant indigène le plus destructeur de l’est du Canada.

Natural disturbance data - Insect: Spruce budworm
Every year, since 1967, the Ministère des Forêts, de la Faune et des Parcs (MFFP) has been conducting an aerial survey of damage caused by the main insects and diseases that attack trees. This fact sheet focuses exclusively on data on damage caused by spruce budworm (TBE).The aerial survey is carried out in sectors previously determined according to the damage of the previous year and the results of inventories to predict the populations of this insect.From 2013 to 2022, the DPF acquired aerial survey videos to obtain additional observer data. Since 2023, high-resolution geotagged images have replaced videos.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
