The objective of the research was to study biology of the Elaeidobius kamerunicus (Coleoptera:Curculionidae) on the oil palm plants in the highlands areas. The research was conducted at PT Perkebunan Nusantara IV Bah Birung Ulu and Laboratory of Plant Pest and Disease Indonesian Oil Palm Research Institute (PPKS) Marihat from November 2016 to April 2017. It was done using by descriptive method. The results showed that the life cycle of E. kamerunicus was 18.6 ± 3.05 days, egg phase, 2.33 ± 0.57 days, the first instar larvae, 2 ± 1.73 days, the second instar larvae, 5 ± 1 days, and the third instar larvae, 2.66 ± 1.15days and the pupa 4.66 ± 0.57 days. Age of male, 10.72 ± 1.4 days faster than female 14.44 ±1.35 days. Preoviposition period was 2 ± 0 days, while oviposition 9.84 ± 0.96 days, and post oviposition 4 ± 0.89 days. The number of eggs laid by a female during her lifetime was 20.4 ± 2.6.
Penelitian ini bertujuan untuk mengetahui biologi serangga penyerbuk Elaeidobius kamerunicus (Coleoptera : Curculionidae) pada tanaman kelapa sawit di daerah dataran tinggi. Penelitian dilaksanakan di perkebunan kelapa sawit PT Perkebunan Nusantara IV Bah Birung Ulu dan Laboratorium Hama dan Penyakit Tanaman Pusat Penelitian Kelapa Sawit (PPKS) Marihat mulai bulan November 2016 sampai April 2017. Penelitian dilaksanakan dengan metode deskriptif. Hasil penelitian menunjukkan bahwa siklus hidup E. kamerunicus yaitu 18,6 ± 3,05 hari,fase telur 2,33 ± 0,57 hari, fase larva instar pertama 2 ± 1,73 hari, fase larva instar kedua 5 ± 1 hari, fase larva instar ketiga 2,66 ± 1,15 hari dan fase pupa 4,66 ± 0,57 hari. Umur imago jantan (10,72 ± 1,4 hari) lebih cepat dari pada imago betina (14,44 ±1,35 hari). Masa prapeneluran yaitu 2 ± 0 hari, masa peneluran 9,84 ± 0,96 hari, masa pasca peneluran 4 ± 0,89 hari. Satu ekor betina semasa hidupnya meletakkan 20,4 ± 2,6 butir telur.
