Abstract

Elaeidobius kamerunicus is one of the weevil pollinator of oil palm. Weevil pollinator, E. kamerunicus in plantation is useful to increase fruit set. Continuity of the oil palm pollination require minimal amount of the weevil. This research to know aggressiveness and population dynamic of the weevil E. kamerunicus in flower of oil palm at Grea Estate PT. Karya Hevea Indonesia. This research uses descriptive analysis method consists of observing and collecting data about the aggressiveness and population dynamics of weevil pollinators visit in anthesis male flowers and receptive female flowers of oil palm of seven years after planting. Observations were made on an hourly basis, starting at 08:00 am until 15:00 pm. Observations were made daily on trees with receptive flowers and anthesis flowers, carried out for 20 days with a different tree every day. The results showed that the aggressiveness of the weevil Elaeidobius kamerunicus as the main oil palm pollinating insect had a significant difference in interest. Where E. kamerunicus tend to be more aggressive to visit the male flower anthesis as many as 1399 tails of the visiting receptive female flower that only 25 tails. Effect of temperature on the population dynamics of E. kamerunicus visit also differ between male flowers and female flowers. For male flowers, E. kamerunicus is more active at 27 ° C. While in the female flowers, E. kamerunicus is active at 30 ° C. E. kamerunicus actively visited male anthesis flowers and receptive female flowers at 63% and 62% moisture respectively.
