Abstract

KEANEKARAGAMAN SERANGGA HAMA PADA TANAMAN KELAPA SAWIT (Elaeis guineensis Jacq) DI KABUPATEN PASAMAN BARAT Abstrak Hama merupakan semua organisme atau binatang yang aktivitas hidupnya menyebabkan kerusakan tanaman sehingga menimbulkan kerugian secara ekonomis bagi manusia. Perbedaan sistem budidaya mempengaruhi populasi dan tingkat keanekaragaman serangga hama tanaman kelapa sawit. Penelitian ini bertujuan untuk mengetahui keanekaragaman serangga hama pada tanaman kelapa sawit (Elaeis guineensis Jacq.) di Kabupaten Pasaman Barat. Metode pengambilan sampel menggunakan Chemical knockdown dengan menggunakan pestisida berbahan aktif Deltametrin 25 g/l. Sampel dikoleksi di Laboratorium Bioekologi Serangga, Fakultas Pertanian, Universitas Andalas. Data dianalisis menggunakan indeks Shannon-Wienner, Pielou, dan indeks kesamaan. Total serangga hama tanaman kelapa sawit yang dikoleksi pada penelitian ini 1142 individu yang terdiri atas 2 ordo, 6 famili, dan 10 spesies. Keanekaragaman spesies pada lokasi PTPN VI yaitu 1,99 dan Perkebunan rakyat Gunung Malintang yaitu 1,69. Spesies serangga hama tanaman kelapa sawit yang dominan dilokasi PTPN VI Unit Usaha Ophir dan Perkebunan Rakyat Gunung Malintang yaitu Mahasena corbetti. Kata kuci : keanekaragaman, serangga hama, kelapa sawit DIVERSITY OF INSECT PESTS ON SAWIT COCONUT PLANT (ElaeisguineensisJacq) IN PASAMAN BARAT DISTRICT Abstract Pests are all organisms or animals whose life activities cause damage to plants, causing economic losses to humans. Differences in agriculture systems affect the population and diversity of oil palm pests. This study aims to determine the diversity of insect pests in oil palm (Elaeis guineensisJacq.) West Pasaman. The sampling method uses chemical knockdown using pesticides made from Deltamethrin 25 g / l. Samples were collected at the Insect Bioecology Laboratory, Faculty of Agriculture, Andalas University. Data were analyzed using the Shannon-Wienner, Pielou, and similarity indexes. The total insect pests of oil palm plants collected in this study were 1142 individuals consisting of 2 orders, 6 families, and 10 species. Species insect pest diversity at the PTPN VI location was 1.99 and the Gunung Malintang smallholder estate was 1.69. The predominant species of oil palm plant insect pests in the location of the Ophir PTPN VI Business Unit and the Gunung Malintang People's Plantation is Mahasena corbetti. Key words: diversity, pest insects, oil palm
