dc.description.abstractA study was carried out at Kayangulam during 1967-70 with a view to evolving a sampling technique for estimating the population of Opisina arenosella Walker one of the serious pests of the coconut palm in India. Leaflet-wise and leaf-wise counts of the pest were recorded from 50 young palms, for 36 months. The middle leaves and leaflets were found to lodge more number of caterpillars than the other parts of the palm (with minimum C. V.%). Linear regression equations were fitted for estimating the total pest population of a palm by counting the pests in the middle 41-60 per cent of leaflets of the first 20 per cent of leaves from the bottom.en_US
