Abstract

Taman Kehati merupakan lokasi konservasi sumberdaya hayati yang memiliki potensi sebagai habitat satwa polinator seperti ngengat. Keanekaragaman ngengat dapat dihubungkan dengan keanekaragaman tumbuhan khususnya yang menjadi tanaman inang dan tanaman pakan. Tujuan penelitian ini yaitu untuk mengetahui keanekaragaman ngengat di Taman Kehati Provinsi Jawa Timur. Pengambilan sampel ngengat menggunakan insect net, light sheet dan light trap di tiga lokasi pengamatan (T1, T2, dan T3) yang merepresentasikan perbedaan vegetasi pada setiap bulan antara Februari hingga April 2021. Hasil pengamatan dianalisis menggunakan indeks Shannon-Wiener (H’) dan indeks dominansi Simpson (D). Analisis komposisi dan kelimpahan tumbuhan dilokasi pengamatan dilakukan dengan metode analisis vegetasi. Hasil yang diperoleh pada ketiga lokasi pengamatan terdapat sebanyak 83 spesies ngengat yang didominasi oleh famili Geometridae, Crambidae, Erebidae dan Noctuidae. Spesies yang selalu dijumpai pada ketiga lokasi pengamatan dengan kelimpahan tinggi yaitu Scopula perlata, Pygospilla tyres, Chiasmia emersaria dan Gesonia obeditalis. Nilai H’ di T1 sebesar 3,28 dan T3 sebesar 3,19 termasuk dalam kategori tinggi serta T2 sebesar 2,93 atau termasuk kategori sedang. Nilai rata-rata H’ untuk Taman Kehati sebesar 3,47 atau termasuk kategori tinggi. Nilai dominansi D pada lokasi T1, T2, T3 sebesar 0,073; 0,095;0,066. Keanekaragaman tumbuhan tidak mempengaruhi tingkat keanekaragaman ngengat. Ketersediaan tanaman inang dan pakan yang mempengaruhi tingkat keanekaragaman ngengat di Taman Kehati. Lokasi T1 memiliki keanekaragaman paling tinggi diduga akibat lokasi T1 memiliki kelimpahan tanaman inang dan pakan yang paling tinggi meskipun keanekaragaman tanamannya rendah.

Biodiversity Park is a biological resource conservation that has potention as a habitat for pollinator animals such as moths. The diversity of moths can be related with the diversity of plants, especially for host plants and feed plants of moths. The purpose of this study was to determine the diversity of moths in the Biodiversity Park, East Java Province. Moths sampling methods using insect nets, light sheets and light traps at three different locations (T1, T2, and T3) that could represent differences vegetation in every locations from Februari until April 2021. Data analyzed using the Shannon-Wiener (H’) index and Simpson (D). Analysis of the composition and abundance of plants using the vegetation analysis method. The results was found 83 species of moths dominated by the families of Geometridae, Crambidae, Erebidae, and Noctuidae. Dominated species at the three observation locations with high abundance were Scopula perlata, Pygospilla tyres, Chiasmia emersaria, and Gesonia obeditalis. The the Shannon-Wienner (H') species diversity index at T1 was 3.28 and T3 was 3.19 which was high category and T2 was 2.93 which was medium category. The overall value of H' for all locations is 3.47 which was high category. The value of D dominance at locations T1, T2, T3 is 0.073; 0.095; 0.066. Plant diversity does not affect the level of moth diversity. Availability of host and feed plants that affect the level of moth diversity in the Biodiversity Park. T1 has the highest diversity, assumed due to T1 have the highest abundance of host and food plants although its plant diversity is low.
