Abstract

ABSTRAK Serangga pengunjung bunga memiliki peran yang sangat penting, karena beberapa spesies serangga pengunjung bunga berperan sebagai agen penyerbuk pada tanaman kelapa sawit. Penelitian ini bertujuan untuk mempelajari keanekaragaman serangga pengunjung bunga pada tanaman kelapa sawit. Penelitian ini dilaksanakan di Nagari Sungai Dareh, Gunung Selasih, IV Koto, Kec. Pulau Punjung, Kab. Dharmasraya dari bulan Oktober sampai Desember 2017.. Pengambilan sampel menggunakan hand collecting, insect net, dan yellow pan trap. Data keanekaragaman spesies dianalisis menggunakan indeks Shannon-Wiener, kemerataan spesies menggunakan indeks Simpson serta dominasi spesies menggunakan indeks nilai penting. Hasil penelitian ditemukan sebanyak 25.900 individu, 10 ordo dan 30 famili. Indeks keanekaragaman pada bunga jantan adalah 0,52 dan indeks keanekaragaman pada bunga betina adalah 0,96. Indeks kemerataan pada bunga jantan yakni 0,27 dan kemerataan bunga betina yakni 0,32. Indeks keanekaragaman dan kemerataan Nagari Gunung Selasih yaitu 1,35 dan kemerataan 0,59. Dinagari IV Koto indeks keanekaragaman yakni 1,50 dan indeks kemerataan yakni 0,67 sedangkan Nagari Sungai Dareh indeks keanekaragaman yakni 1,37 dan kemarataan 0,42. Ordo Coleoptera famili Curculionidae memiliki indeks nilai penting tertinggi yaitu 1,00. Kata kunci : Curculionidae, penyerbukan, polinator dan serbuk sari ABSTRACT Insects visitors of flower have a very important role on oil palm plants, because some species of insect act as pollinating agents.This study aims to study the insec’t diversity of visitor flowers in oil palm plants. This research was conducted in Nagari Sungai Dareh, Gunung Selasih, IV Koto, Kec. Punjung Island, Kab. Dharmasraya. During the period of October to Desember. The sampling taken by used hand collecting, insect net, and yellow pan trap. Species diversity data were analyzed using the Shannon-Wiener index, evenness of species using the Simpson index and species dominance using important value indexes.The results of the study found 25,900 individuals, 10 orders and 30 families. The diversity index in male flowers is 0.52 and the diversity index in female flowers is 0.96. While the evenness index in male flowers is 0.27 and the female flower evenness index is 0.32.Diversity index and evenness of Nagari Gunung Selasih is 1.35 and evenness is 0.59. Dinagari IV Koto diversity index is 1.50 and the evenness index is 0.67 while Nagari Sungai Dareh diversity index is 1.37 and equality is 0.42. Order of the Coleoptera family of Curculionidae has the highest important value index of 1.00. Keywords: Curculionidae, pollination, pollinators and pollen
