Abstract

Abstrak

Capung jarum (Zygoptera) berperan penting bagi keberlangsungan ekosistem.Pada suatu ekosistem, serangga ini berfungsi sebagai agen pengendali hayati dan bioindikator lingkungan.Penelitian ini bertujuan untuk menganalisis kelimpahan capung jarum yang ada pada tiga habitat di Kawasan Taman Nasional Bogani Nani Wartabone, Sulawesi Utara.Pengambilan sampel dilakukan secara purposive random sampling. Koleksi capung jarum  menggunakan teknik sweepingmengikuti garis transek sepanjang 500 m pada setiap tipe habitat. Jumlah transek pada setiap tipe habitat sebanyak 3 garis transek yang dibuat sepanjang aliran sungai.Hasil penelitian didapatkan sebanyak 13 spesies capung jarum yang terdiri dari 4 famili, yaitu Coenagrionidae, Chlorocypidae, Calopterygidae, dan Platycnemididae. Famili yang paling banyak ditemukan jumlah spesiesnya adalah Coenagrionidae, sedangkan yang paling sedikit Platycnemididae. Berdasarkan tipe habitat, jumlah spesies yang paling banyak ditemukan di hutan primer sedangkan yang paling sedikit di hutan sekunder.Kelimpahan capung jarum tertinggi terdapat pada lahan pertanian, sedangkan kelimpahan terendah pada habitat hutan primer

Abstract

Damselfly (Zygoptera) plays important roles in the environment and this organism ia able to be used as biocontrol and bioindicator. This research was aimed to analyze the abundance of damselfly that werelocated at three different habitats in Bogani Nani Wartabone National Park, North Sulawesi. The purposive random sampling method was used to collect the samples. Damselflies were taken by using sweeping technique following 500 m transect line in each habitat. There were three transect lines in each habitat located along the river. The results showed that there were thirteen species from 4 families (Coenagrionidae, Chlorocypidae, Calopterygidae, and Platycnemididae) of damselfly. Most species were members of Coenagrionidae whereas the others werePlatycnemididae Family. Based on the types of habitat, the highest number of species was found in the primary forest, whereas the smallest number was in the secondary forest. Greatest the abundance of damselfly was the largest in the agricultural area and the smallest was in the primary forest.
