Explanation:
Detailed explanation-1: -Biological control is the use by humans of beneficial insects such as predators and parasitoids, or pathogens such as fungi and viruses, to control unwanted insects, weeds, or diseases. Biological control dates back to 324 BC, when Chinese growers were recorded using ants to feed on citrus pests.
Detailed explanation-2: -Often, the natural enemies are found in the home range of the invasive pest. Some notable examples of classical biological control include the use of decapitating flies (several Pseudacteon species) against red imported fire ants, and a group of flea beetles, thrips, and stem borers used against alligator weed.
