Answer:
Importation, augmentation and conservation of natural enemies constitute the three basic approaches to biological control of insects.
Explanation:
Importation of natural enemies, sometimes referred to as classical biological control, is used when a pest of exotic origin is the target of the biocontrol program.
Augmentation is the direct manipulation of natural enemies to increase their effectiveness. This can be accomplished by one, or both, of two general methods: mass production and periodic colonization; or genetic enhancement of natural enemies.
Conservation In any biological control effort, conservation of natural enemies is a critical component. This involves identifying the factor(s) which may limit the effectiveness of a particular natural enemy and modifying them to increase the effectiveness of the beneficial species. In general, conservation of natural enemies involves either, reducing factors which interfere with natural enemies or providing resources that natural enemies need in their environment.
