The pest later established in various locations of Kerala, Karnataka and Tamil Nadu. The mite infests buttons and colonising inside the perianth sucks sap from the tender tissues resulting in button shedding, reduction of both nut size and kernel content as well as loss of husk. The life cycle is completed in.7-10 days. The pest can be managed by periodic spray of insecticides like monocrotophos, dicofol and wettable sulfur. Botanicals such as neem oil, garlic, fish oil, rosin soap etc are preferred, though less effective, due to their ecofriendliness. Proper management of the palms helps to contain the pest and reduce economic loss. Hirsutella thompsonii is regarded as a potential biological agent. No cultivar is resistant to the pest. but%cer tain features like round shape of nut, tight petals etc. offer some tolerance. An uptodate review on the pest in India is presented along with suggestions on future course of action.Item Coconut leaf Beetle(Brontispa longissima)-An inavasive pest of concern(2009-10) Rajan, P.; Nair, C.P.R.; Josephrajkumar, A.; Chandrika MohanItem Coconut root wilt - The malady and remedy(2007-02-08) Solomon, J.J.; Nair, C.P.R.; Srinivasan, N.; Gunasekaran, M.; Sasikala, M.Item Coconut sector in Kerala economy - role, peformance & contribution(1) George V.

NairItem Growth and vigour of coconut seedlings raised from eriophyid mite (Aceria guerreronis Keifer) infested seed nuts(2004-12) Thomas, R.J.; Nair, R.V.; Nair, C.P.R.; Nampoothiri, C.K.; Cherian MathewsConsidering the wide spread apprehension regarding suitability of mite infested seed nuts for raising seedlings, a study was undertaken to evaluate the growth and vigour of coconut seedlings raised from mite-infested seed nuts. The maximum values for all the growth characters were recorded in seedlings raised from grade-3 infested seed nuts. However, higher percentage of vigorous seedlings (with Z score of 22 and above) was obtained in seedlings raised from uninfested I grade-0 nuts. The faster germination recorded in grade-3 infested nuts and their subsequent better establishment may be the reasons for the superior performance of seedlings raised. On the basis of the present investigation, it is recommended that mite infested seed nuts should be sorted into lots. depending on severity of infestation. and nursery raised separately for each lot so that competition between seedlings, raised from different grades of mite infested nuts, can be minimized. This will help in obtaining more vigorous seedlings from the mite infested seed nuts.
