Biological Control_

  Biological management or biocontrol could be a methodology of dominant pests like insects, mites, weeds and plant diseases mistreatment alternative organisms.It depends on predation, parasitism, herbivory, or alternative natural mechanisms, however generally conjointly involves a full of life human management role. It may be a vital element of integrated tormentor management (IPM) programs.There area unit 3 basic methods for biological tormentor control: classical (importation), wherever a natural enemy of a tormentor is introduced within the hope of achieving control; inductive (augmentation), within which an outsized population of natural enemies area unit administered for fast tormentor control; and inoculative (conservation), within which measures area unit taken to take care of natural enemies through regular reestablishment.Natural enemies of insect pests, conjointly referred to as biological management agents, embrace predators, parasitoids, pathogens, and competitors. Biological management agents of plant diseases area units most frequently remarked as antagonists. Biological management agents of weeds embrace seed predators, herbivores and plant pathogens.Biological management will have side-effects on diversity through attacks on non-target species by any of constant mechanisms, particularly once a species is introduced while not thoroughly understanding the doable consequences. Augmentation involves the supplemental unleash of natural enemies that occur during an explicit space, boosting the present populations there. In inoculative unleash, little numbers of the management agents are discharged at intervals to permit them to breed, within the hope of fitting longer-term management, and therefore keeping the tormentor right down to an occasional level, constituting bar instead of cure.
