Some nonnative insect species have become pests in the United States. To control and manage these insect pests, several different types of control have been designed:
Biological controls: A natural predator of the insect pest species is introduced into the areas that are most harmed by the insect pest.
Cultural controls: People are educated in ways that help to minimize the impact of nonnative insect pest species. For example, farmers can change how they plant or water crops, or people who burn wood can be sure not to transport firewood that may contain the insect pests into new areas.
Mechanical and physical controls: Mechanical and physical controls are used to kill insect pest species directly or to make where they live unsuitable for them. These controls include traps, such as box traps for flies, and physical barriers, such as screens.
Chemical controls: Pesticides are chemicals that either kill the insect pests or lure them into containers where they die. These pesticides are usually liquids that may be broadly sprayed, used as bait, or sprayed in very small areas.
Select one of the controls listed above and evaluate its strengths and weaknesses with respect to maintaining biodiversity. Use complete sentneces.
