    Introduction:
    There is a large population of insect pests which are present the earth, in this
    population various insects are not dangerous for agricultural crops because they are beneficial to
    crops and farmer and fight for crop production against harmful insect pests. Now a days farmers
    are used chemicals continuously to gain high production or yield. Continuous use of these harmful
    chemicals affect environment, natural enemies (predators, parasitoids, and parasites), human
    health and other non-target organisms.
    Resistance can be also produced in insect pests against pesticides by using chemicals
    again and again. Biological control is also known as classical control for insect pest’s .It is very
    significant tool to control target pests naturally in integrated Pest management. One reason is
    behind to use large number of chemicals is the lack of awareness about biological or natural
    control. So farmers should be aware to know positive and negative impact of natural control.
    Some Tools which are used for Natural Control:
    Predators:
    Those organisms which depend on host for food and survive by preying host
    organisms. Total 40 families which are used as a predator to prey insect pests such as
    Anthocoridae, pentatomidae, reduviidae, carabide, syrphidae and vellidae etc.
    Parasites:
    Those organisms which live on living host and get feed from their host and cause death.
     10% species are parasitoids
     43 families –Hymenoptera are parasitoids
     12 families-Diptera are parasitoids
    Recent research have been proved that 26 families which are used in natural control pests.
    Bacteria:
    Eubactariales, Bacillus (bacillaceae, serratia) from family (bacilliaceae) Bacillus thuringensis
    (Bt) using widely as a biotech control.
    Virus:
    Granulosis Viruses, Nuclear Polyhedrosis Viruses (NPV) and Baculovirus
    Fungi:
    Zygomycotina, Mastigomycotina,and Deutromycotina
    Merits and Demerits of Biotic Control:
    Merits:
     Due to natural control against insect’s pests we can save our environment, health, on- target
    organisms from hazard effects of synthetic chemicals.
     It’s not a need of long time, heavy effort and large number of laborers and cost while
    farmers spend more money for spraying.
     It is cost effective, classical and specific target pest control which is not injurious for human
    health and other non-target organisms.
     In case of fruit trees, Fruit will not be damage by biotic or natural control.
     It can be applied under green house or glasshouse conditions
    Demerits:
     Various unknown species present
     If the pests not present then natural enemies cannot survive
     It’s a slow process instead of synthetic chemical pest control
     It’s a costly and requires high expertise and skills if we rear natural enemies.
     It requires a large area for implementation
