    Abstract
    Ecology Research Coffee Pod Borer (Hypotenemus hampei) at Arabica Coffee Plants (Coffea arabica) in District Pakpak Bharat had been conducted in March 2010 - April 2010. Research in the form of this survey sampled at 5 height is: A ≤ 700, 700 < B ≤ 800, 800 < C ≤ 900, 900 < D ≤ 1000, and E > 1000 meters above sea level. This study aims to (a) know H.hampei distribution pattern, (b) measuring the intensity of attacks H.hampei, (c) the composition of stadia development in H.hampei connect with ripeness (green, yellow, red), and (d) know the correlation of physical environmental factors with itensity attacks. The results showed that the distribution pattern of H. hampei clustered in the bottom sector, the intensity of light attacks. Composition of the development of stadia H. hampei more progress on the red colored fruit. Physical environmental factors are not correlated to the intensity of attacks H.hampei.
     
    Penelitian Ekologi Penggerek Buah Kopi (Hypothenemus hampei) pada Tanaman Kopi Arabika (Coffea arabica) di Kabupaten Pakpak Bharat telah dilaksanakan pada bulan Maret 2010 – April 2010. Penelitian yang berupa survei ini mengambil sampel di 5 ketinggian yaitu : A ≤ 700, 700< B≤800, 800<C≤900, 900<D≤1000, dan E>1000 meter di atas permukaan laut. Penelitian ini bertujuan (a) mengetahui pola distribusi H. hampei, (b) mengukur intensitas serangan H. hampei, (c) mengetahui komposisi stadia perkembangan H. hampei di hubungkan dengan kematangan buah (hijau, kuning, merah), dan (d) mengetahui korelasi faktor fisik lingkungan dengan intensitas serangan. Hasil penelitian menunjukkan bahwa pola distribusi H. hampei berkelompok disektor bawah, intensitas serangan ringan. Komposisi perkembangan stadia H. hampei lebih banyak berlangsung pada buah berwarna merah. Faktor fisik lingkungan tidak berkorelasi terhadap intensitas serangan H. hampei.
