Elaeidobius kamerunicus is the most efficient insect pollinator of oil palm. Introduction of the weevil in the oil palm plantations increased the furit set from 36.9 to 78.3 per cent. Maximum number of pollinating weevils congregate on the male infloresceces on the third day of anthesis. Studies on the diurnal variation in the population of Elaeidobius kamerunicus on the anthesising male inflorescences of oil palm revealed that the population of the pollinating weevils are less on the male inflorescences during noon time with some exceptions, especially during rainy months.
