    Study Notes

    Forest Ecology and Insects

    • Forests are home to a diverse range of organisms, including insects.
    • The study of forest insects is known as forest entomology.

    Insects' Roles in Forest Ecosystems

    • Insects play important roles in forests, including serving as food for wildlife, pollinating plants, and preying on forest pests.
    • Some insects cause significant damage to forests, reducing tree growth rates, transmitting diseases, and weakening trees.

    Invasive Insect Species

    • Many forest insect pests are introduced from other countries and have become invasive species.
    • These invasive species have no natural predators, contributing to their destructive impact.

    Classification of Insect Pests

    • Insect pests can be classified by the type of damage they cause.
    • Each insect species has a preferred part of the tree on which it feeds.

    Defoliators

    • Defoliators eat a tree's leaves or needles, stripping them from entire stands of trees.
    • Without leaves or needles, trees cannot make the sugar they need to grow.
    • Heavy infestations of defoliators can:
      • Slow the growth rate of deciduous trees after one year of defoliation.
      • Kill deciduous trees after several years of defoliation.
      • Kill evergreen trees after just one year of defoliation.

    Example of a Defoliator

    • The spongy moth is an example of a defoliator insect.
