Answer:
  • The natural method of pest and pathogen control involving the use of viruses, bacteria, and other insects is called biocontrol or biological control.
  • Examples
  • Growth of cacti in India and Australia was checked by the introduction of its natural herbivore, cochineal insect (Cactoblastis cactorum).
  • Growth of Klamath weed (Hypericum perforatum) was checked in USA by the introduction of Chrysolina beetles.
  • Introduction of ladybugs (Ladybird beetles) and praying mantis have been successfully used to combat scale insects or aphids which feed on plant sap.
  • The virus Baculovirus heliothis can control cotton bollworm Heliothis zea.
  • The bacterium Bacillus thuringiensis can control the cabbage looper Trichoplusia.
