Observations on natural enemies found in association with coconut mite, Raoiella indica Hirst.

Abstract

The natural enemy complex of the coconut pest Raoiella indica was studied in West Bengal, India. The dominant predator was the staphylinid Oligota sp., followed by the predatory mites Phytoseius sp. and Amblyseius sp. The former 2 species showed a positive correlation with the population build-up of the pest, while the latter species was negatively correlated. The peak populations of Oligota sp. and Phytoseius sp. were recorded in June and September, coinciding with peak population of R. indica. The role of predators in the natural control of the pest is discussed.
