PENGARUH PEMBERIAN BERBAGAI JENIS PAKAN TERHADAP LAJU METAMORFOSIS NGENGAT ATLAS (Attacus atlas L.) DI TAMAN KUPU-KUPU KEMENUH, GIANYAR

Abstract

Ngengat atlas kini sulit dijumpai di alam Bali. Hal tersebut disebabkan oleh proses perkawinan yang sulit terjadi, ancaman serangan predator, perubahan lingkungan, dan manusia. Dikhawatirkan ngengat atlas akan mengalami kepunahan, sehingga diperlukan usaha pelestarian. Pakan merupakan salah satu hal yang mempengaruhi pertumbuhan dan perkembangan, serta laju metamorfosis ngengat atlas. Penelitian ini bertujuan (1) mengetahui perbedaan laju metamorfosis ngengat atlas dengan pemberian pakan yang berbeda dan (2) mengetahui jenis pakan yang mampu menghasilkan laju metamorfosis paling cepat. Penelitian ini merupakan penelitian eksperimental sungguhan dengan rancangan the posttes-only control group design. Pada penelitian ini menggunakan 30 sampel larva instar I. Berdasarkan hasil penelitian menunjukkan adanya perbedaan laju metamorfosis dengan pemberian pakan yang berbeda. Pakan daun dadap menghasilkan rerata laju metamorfosis paling cepat, yaitu 70,6 hari dengan rerata fase telur selama 10 hari, fase larva selama 32,2 hari, fase pupa selama 23 hari, dan fase imago selama 5,4 hari.

Atlas moth is now difficult to find in nature Bali. This was caused by the mating process to be difficult, the threat of attack by predators, environmental change, and human.Atlas moth is feared to be extinct, so that the necessary conservation efforts. Feed is one of the things that affect growth and development, as well as the rate of metamorphosis moth atlas. This study aims to (1) determine differences in the rate of metamorphosis moth atlas with different feeding and (2) determine the type of feed that can produce the most rapid rate of metamorphosis. This research is a real experimental design with the posttes-only control group design. In this study using 30 samples instar larvae I. Based on the results of the study indicate differences in rates of metamorphosis by feeding different. Feed leaves dadap produce the fastest average rate of metamorphosis, ie 70.6 days with a mean egg phase for 10 days, 32.2 days during the larval stage, pupa for 23 days, and the imago phase for 5.4 days.
