Knowledge and Information
Of all the trees on the planet, the most appreciated are the ornamental trees which are planted in our communities, purifying our air and beautifying our environment every day. Urban trees improve air quality; they increase property value, protect us from UV rays, mitigate the heat island phenomenon and influence our behavior, our interactions and appreciation of a place.
Unfortunately, urban trees are sometimes threatened by insect pests including the emerald ash borer (Agrilus planipennis), the spruce budworm (Choristoneura fumiferana), gypsy moth (Lymantria dispar Linnaeus) and forest tent caterpillar (Malacosma americanum). These pests, exotic or native, grow at the expense of trees and lead to tree decline or death, threatening our environment and the benefits provided to us.
In the wild, forest insect populations are generally in balance, controlled by predators, parasitoids and pathogens, as well as a limited resource and variable environmental conditions. When an insect lands by accident in a new ecosystem without natural enemies, this can lead to catastrophic situations for biodiversity … and our living environment!
