Insekta pohon berperan penting bagi keberlangsungan ekosistem di kebun campuran, keberadaan insekta pohon di kebun campuran dipengaruhi oleh faktor lingkungan dan aktivitas manusia dalam mengelola kebun campuran. Penelitian ini bertujuan untuk mengetahui spesies insekta pohon, indeks keanekaragaman, indeks dominansi dan peranan insekta pohon di kebun campuran Gampong Meunasah Raya, Kecamatan Jangka Buya, Kabupaten Pidie Jaya. Penelitian ini menggunakan pendekatan kuantitatif dan jenis penelitian deskriptif, adapun metode yang digunakan yaitu metode survei dengan teknik purposive sampling. Pengambilan data dalam penelitian ini menggunakan dua cara yaitu perangkap jebak umpan (bait trap) dan pengambilan langsung dengan tangan (hand collecting). Keanekaragaman insekta dianalisis menggunakan rumus indeks keanekaragaman Shannon-Wiener dan indeks dominansi insekta pohon dianalisis menggunakan rumus indeks dominansi Simpson. Hasil penelitian ditemukan 10 spesies insekta pohon yaitu Camponotus compressus, Dolichoderus thoracicus, Camponotus sansabeanus, Oecophylla smaragdina, Camponotus barbaricus, Solenopsis invicta, Lasius niger, Poecilus versicolor, Chilocorus renipustuatus dan Scutiphora pedicellata dengan total 250 individu, yang berasal dari 4 famili dan 3 ordo. Indeks keanekaragaman insekta pohon di kebun campuran yaitu (H’) = 1,411-1,936 dan indeks dominansi yaitu (C) = 0,148-0,269. Insekta pohon menguntungkan yang ditemukan di kebun campuran yaitu Camponotus compressus, Dolichoderus thoracicus, Camponotus sansabeanus, Oecophylla smaragdina, Camponotus barbaricus, Solenopsis invicta, Lasius niger, Poecilus versicolor, Chilocorus renipustuatus dan insekta yang merugikan yaitu Scutiphora pedicellata.

Novi Susanti. (2026). Diversity of Tree Insects in the Mixed Garden Area of Gampong Meunasah Raya, Jangka Buya District, Pidie Jaya Regency. [Script. Universitas Syiah Kuala]. Under direction of Prof. Dr. M. Ali S., M.Si., and Yaumil Istiqlal M.Nur, S.Pd.I,. M.Pd. Tree insects play an important role in the sustainability of ecosystems in mixed gardens. The diversity of tree insects in mixed gardens is influenced by environmental factors and human activities in managing mixed gardens. This study aims to determine the species of tree insects, their diversity levels, dominance levels, and their roles in mixed gardens in Gampong Meunasah Raya, Jangka Buya District, Pidie Jaya Regency. This study uses a quantitative approach and descriptive research type, while the method used is a survey method with a purposive sampling technique. Data collection in this study uses two methods: bait traps and direct collection (hand collecting). The level of tree insect diversity was analyzed using the Shannon-Wiener diversity index formula and the level of tree insect dominance was analyzed using the Simpson dominance index formula. The results of the study found 10 species of tree insects, namely Camponotus compressus, Dolichoderus thoracicus, Camponotus sansabeanus, Oecophylla smaragdina, Camponotus barbaricus, Solenopsis invicta, Lasius niger, Poecilus versicolor, Chilocorus renipustuatus and Scutiphora pedicellata with a total of 250 individuals, originating from 4 families and 3 orders. The diversity index of tree insects in mixed gardens is (H’) = 1,411-1,936 and the dominance index (C) = 1,411-1,936. Beneficial tree insects found in mixed gardens are Camponotus compressus, Dolichoderus thoracicus, Camponotus sansabeanus, Oecophylla smaragdina, Camponotus barbaricus, Solenopsis invicta, Lasius niger, Poecilus versicolor, Chilocorus renipustuatus and harmful insects are Scutiphora pedicellata..
