Abstract
Oil palm (Elaeis quineensis Jacq) is a monoecious plant whose pollination process requires pollinating agents such as insects (entomophily). The dominant insect in oil palm flowers is Elaeidobius kamerunicus. The presence of E. kamerunicus can increase the value of fruit sets of oil palm bunches. This study aims to study and analyze the diversity and behavior of E. kamerunicus pollinators in flowering oil palm. The purposive sampling method is used to determine the sample plants used, while the observation of visiting behavior used the focal sampling method. Based on the observation of diversity in oil palm flowers obtained 16 morphospecies namely E. kamerunicus, Gelechiidae sp. 01, Chelisoches sp. Rhabdoscelus sp, Forficula sp, Velinus nigrigenu, Salticidae sp. 1, Formicinae sp.1, Tirathaba sp, Rhinocoris fuscipes, Thrips hawaiiensis, Formicinae sp.2, Metisa sp, Tetragnathide sp. 1, Thomisidae sp. 1, Euchantecona sp. with a dominance index of 0.89, diversity index and evenness index were 0.33 and 0.12. Based on the observation of the behavior of E. kamerunicus, it was found that the duration of E. kamerunicus visit was 17.87 seconds / flower, with the length of activity in the first, second and third day on male flowers respectively were 3.29 minutes, 1.39 minutes and 0.57 minutes, the visit rate of E. kamerunicus based on female flowers and male flowers were 2.32 flowers / minute and 3.18 flowers / minute while the visit rate based of male and female E. kamerunicus on male flowers were 3.53 flowers / minute and 2.84 flowers / minute with a period of time of E. kamerunicus visit on female flowers at 9 a.m -1 p.m and the average number of male and female E. kamerunicus on female oil palm flowers respectively were 5.02 individuals and 14.96 individuals. Keywords: Oil Palm Flowers, Diversity, Behavior, Elaeidobius kamerunicus
