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.
