Agricultural entomology seems to go hand-in-hand with pest management. When insects invade and destroy crops, agricultural entomologists are called in to eradicate the problem. They can use pesticides, introduce predator insects that won't harm crops and plants, and plant crops that keep pests at bay. Farmers work with agricultural entomologists on a regular basis. They rely on them to keep their crops free from pesticides. The damage to crops from insect pests can approach a 25 percent loss of yield.

Some insects attack crops, while others destroy trees and ornamental plants. By feeding on the roots, foliage, or fruit, insects can wipe out an entire crop or do enough economic damage that farmers will call on entomologists for help. Agricultural entomologists research insects of economic importance and work to prevent the introduction of exotic insects that may harm crops, trees, and other beneficial plants.

Agricultural entomologists work out in the field and in universities, as well as in private industry. In addition to their agricultural work, they educate the public about insect pests, pesticides, and pest management.

Although agricultural entomologists spend a good deal of time outdoors, they also spend a lot of time doing research and filling out paperwork. If you are interested in becoming an agricultural entomologist, you should have a background in math and science. Of course, you will need a degree in entomology. A master's degree gives you an edge in gaining employment on the state or federal level or in private corporations. The average annual salary for agricultural entomologists is $62,000.

Opportunities are on the rise, since highly trained agricultural entomologists are needed to combat pests that have adapted to chemically based fertilizers and insecticides. They are needed to practice sustainable agriculture, which balances crop output with preservation and protection of various ecosystems.
