Farmers have always been concerned with the insect life that is active within their crops. Some insect pests are native to America, and others are not. Insect pests that originate from other countries are particularly devastating to many forms of plant life here in America. This is because foreign insects do not have any natural predators in America, which allows foreign insects to build enormous populations. These large insect pest populations can become difficult to control. Now, with the current reality of climate change, some regions of the US could experience an influx of certain insect pests. For example, insects that commonly thrive in the south could move northward as the climate gradually warms. According to a recent report issued by various academics, the economic impact that invasives have on the American economy equals about 27.3 billion dollars.
