Abstract
Abstract Major pests of tea and their natural enemies on record in India and Sri Lanka are presented with emphasis on their utility. Mite pests of tea are subjected to predation mainly by coccinellids and phytoseiid mites to a considerable extent in those gardens where insecticidal applications are restricted. Effective control of Homona coffeae in Sri Lanka was achieved with the larval parasite Macrocentrus. In northeast India the leaf roller Gracillaria theivora was kept in check by two efficient parasites, and a bacterial disease of Ardraca bipunctata almost prevented outbreaks of that pest. The artificial dissemination of bacteria and granulosis virus could help to spread these diseases among nettle grubs. Insecticidal applications may adversely affect the parasites and predators of the untargeted pests and could cause outbreaks of minor pests such as Homona and Gracillaria. The use of chemical pesticides can be minimised by integrating with the other available methods of control.
