Problem areas on the control of this serious pest in India and Sri Lanka are then identified. Additional studies on the fields for each aspects of the pest are suggested to come up with possible source of materials necessary in formulating a feasible integrated control measures which are both economical and effective.Item The concept, philosophy and feasibility of integrated pest control with particular reference to coconut(2007-02-08) Chandy Kurian; Ponnamma, K.N.; Abdulla Koya, K.M.Item Control of Arecanut Spindle Bug Carvalhoia arecae M. and C. using Granular Insecticides in the Field(2007-02-08) Sathiamma, B.; Abdulla Koya, K.M.; Rawther, T.S.S.; Chandy KurianGranular formulations of phorate, lindane and quinalphos were tested under field conditions in demonstration cum trial plots at CPCRI, Research Centre, Palode during 1977-1980. Trials proved that granular formulations of lindane and phorate, applied to the innermost two or three leaf axils @ 10 g per palm at quarterly intervals, in March, June, September and December effected significant control of the spindle bug population in the field. The cost of the insecticide granule+labour for treatment of 100 palms worked out to Rs. 301- for lindane and Rs. 381- for phorate.Item Distribution of Dipteran Maggots associated with ginger (Zingiber officinale Rose.) in Kerala(2007-02-08) Abdulla Koya, K.M.Item Efficacy of two indigenous traps for trapping rodents in a coconut plantation(2007-02-08) Chandy Kurian; Natarajan, P.; Abdulla Koya, K.M.The effectiveness of two rat traps, bamboo snap back-rum-noose trap and plank trap/ death fall trap, was tested in a coconut plantation (23.5 ha area) for 24 months and 9 months, respsctively. The former gave 15.5% catch of Bandicota bengalensis and the latter gave 24.6% catch of three rat species Bandicota indica, Rattus rattus, and Tatera indica.Item Evaluation of seven insecticides for control of red palm weevil Rhynchophorus ferrugineus Fabr.(2007-02) Abraham, V.A.; Abdulla Koya, K.M.; Chandy KurianSeven insecticides, viz., dichlorvos, phosphamidon, methyl-o-demeton, trichlorphon, para-thion, malathion, and arprocarb, were tested in the laboratory in various concentrations for their effectiveness against the grubs of red palm weevil Rhynchophorus ferrugineus. Dichlorvos at 0 -25%, methyl-o-demeton, phosphamidon, ard arprocarb at 0 -5%, trichlorphon and malathion at 1 -0%, and parathion at 2-0% gave 100% mortality on the seventh day. The three insecticides, with the lowest LC 90 values, dichlorvos, trichlorphon, and arprocarb, were tested in the field on naturally infected palms and trichlorphon gave the best results with 92% recovery of infested palms.Item Evaluation of six granular insecticides for the control of arecanut spindIe bug, Carvalhoia arecae Miller and China in the field(1979-08) Abdulla Koya, K.M.; Rawther, T.S.S.; Sathiamma, B.; Chandy KurianSIX granular insecticides VIZ. lindane 60, carbaryl+ lindane 4 : 40, carbaryl 40, mephosfolan 50, thiodemeton 50 and quinalphos 50 were tested in the field against the spindle bug, Canalhoia arecae Miiler and China on arecanut palm. All the insecticides effected control of the pest. However, quinalphos was superior to mephosfolan and thiodemeton.Item Field evaluation of BHC carbaryl and endosulfan for the control of the coconut coreid bug, Paradasynus rostratus Distant(2007-02) Ponnamma, K.N.; Chandy Kurian; Sukumaran, A.S.; Abdulla Koya, K.M.Field evaluation of BHC, car-baryl and endosulfan for the control of coconut coreid bug, Paradasynus rostratus Distant was carried out. Results revealed that it is advisable to use carbaryl 0.05 per cent or endosulfan 0.1 per cent for the control of this coreid bug.Item Field evaluation of BHC, Carbaryl and Endosulfan for the control of the coconut coreid bug, Daradasynus rostratus Distant(1985-02) Ponnamma, K.N.; Chandy Kurian; Sukumaran, A.S.; Abdulla Koya, K.M.Item Insect Pests of Black Pepper Piper Nigrum L. in India(2007-02) Devasahayam, S.; Prem Kumar, T.; Abdulla Koya, K.M.The information available on distribution, nature and extent of damage, life history, seasonal abundance, natural enemies and control measures of various insect pests infesting black pepper Piper nigrum L. in India has been reviewed.Item Integrated Management of Red Palm Weevil (Rhynchophorus Ferrugineus F.) in Coconut Gardens(2007-02) Abraham, V.A.; Abdulla Koya, K.M.; Chandy KurianThe red palm weevil, Rhynchophonis femigineus F., is a dreaded pest of the coconut palm, capable of killing the palm outright. Though different methods of management have been recommended against this pest, any single method has not been proved to be effective in combating the pest infestation. Timely adoption of curative chemical control can protect the palms from pest infestation. But being a tissue borer, the infestation is quite often detected at later stages only and as such it would be difficult to save the palm with the curative treatment. Hence, an integrated method of pest management system was developed and tested in cultivators gardens in Alleppey District. The schedules included adoption of plant and field sanitation, prophylactic method of filling all the leaf axils of palms with BHC + sand, curative chemical treatment, preventation of pest entry through cut ends of petioles and wounds and use of attractants. Sixty nine out of a total of 1005 young experimental palms were infested by the pest at the time of commencement of the experiment during 1970. By adoption of all the proven methods of weevil control in an integrated manner die pest infestation could be brought down near to zero level and the gardens could be maintained free of fresh infestation.Item Magnitude of the Rat Problem and Possible Solution(2007-02) Abdulla Koya, K.M.; Natarajan, P.; Chandy KurianItem Myllocerus curvicornis (F.), A New Pest of Coconut(2007-02) Chandy Kurian; Abraham, V.A.; Ponnamma, K.N.; Abdulla Koya, K.M.Item A New Enemy of Coconut in India(2007-02) Chandy Kurian; Abraham, V.A.; Abdulla Koya, K.M.Item Record of Rhinocoris Fuscipes (Fabr.)

(Coleoptera:Curculionidae), the Ash Weevil Pest of the Coconut Palm(1979) Ponnamma, K.N.; Chandy Kurian; Abdulla Koya, K.M.Item Record of Wax Scale Ceroplastes Floridensis Comstock (Homoptera: Coccidae) Infesting Clove Seedlings In Kerala, India(1989) Vidyasagar, P.S.P.V.; Abdulla Koya, K.M.; Devasahayam, S.; Prem Kumar, T.Ceroplastes fioridensis Comstock (Hemoptera : Coccidae) has been recordef for the first time infesting clove seedlings in Kerala, IndiaItem Rodent Control(1976) Natarajan, P.; Chandy Kurian; Abdulla Koya, K.M.Item Seasonal Fluctuations in Population of the Spindle Bug Carvalhoia arecae M. and C.(Heteroptera : Miridae)(1985) Sathiamma, B.; Abdulla Koya, K.M.; Abraham, V.A.; Rawther, T.S.S.; Chandy KurianThe spindle bug Carvalhoia arecae is one of the major pests of arecanut palm. The bugs suck sap from the tender tissues of the spindle leaf and cause necrotic lesions. Seasonal fluctuation in population of the spindle bug studied at three locations revealed that the pest occurred throughout the year. The peak period of the pest abundance was found to vary at different centres. The peak period of occurrence was in January and November at Krishnapuram, in July at Palode and in February at Sullia. High pest population was noted at Krishnapuram and Palode whereas it was quite low at Sullia. Among the weather factors, positive correlation was observed with rainfall and pest population.Item Sexing Live Adults of the Pollu Beetle Longitarsus Nigripennis Mots.
