| dc.description.abstract | The total population of Stephanitis typicus Distant, a pest of coconut foliage, could be projected from the sample population obtained by counting the total number of pests present on 20% leaflets at the middle region of 20% leaves. The innermost leaves were taken for sample in each palm. The sample population multiplied by a constant (3-76) gave the estimated population within 5% error on groups of palms, the number in each group being not less than 10. | en_US |
