Abstract

Introduction of the pollinating weevil (Elaeidobius kamerunicus Faust; of oilpalm (Elaeis guineensis Jacq.) in India increased the fruit set from 36.87 to 56.10%, resulting in 40% increase in bunch weight and 11% increase in fruits : bunch ratio. Weevil pollination also decreased the parthenocarpy from 34.3 to 24.3%, resulting in 28.4% reduction in parthcnocarptc fruit: weight ratio. Though wind-f assisted pollination (60.45%) was more efficient than the wind + weevil pollination (56.10%); the latter produced compact bunches owing to pollination of even the spikelets at the bottom of the inflorescences by weevils.
