Nisa, Khoirun (2020) Toksisitas Minyak Kemiri Sunan (Reutealis Trisperma) Terhadap Mortalitas, Pertumbuhan, Dan Perkembangan Ulat Krop (Crocidolomia Binotalis Zell. Sarjana thesis, Universitas Brawijaya.
Abstract
Crocidolomia binotalis Zell atau secara umum dikenal sebagai ulat krop merupakan hama utama sayuran famili Brassicaceae. Umumnya digunakan insektisida sintetik dalam pengendaliannya. Insektisida sintesis berpotensi menimbulkan resistensi dan meningkatkan residu pada tanaman dan berdampak buruk bagi kesehatan manusia. Salah satu upaya dalam mengurangi pengunaan pestisida kimia adalah dengan pemanfaatan insektisida nabati. Penelitian ini bertujuan menganalisis pengaruh dan dosis efektif minyak kemiri sunan terhadap mortalitas, pertumbuhan, dan perkembangan ulat krop (Crocidolomia binotalis Zell) sebagai pestisida nabati. Penelitian dilakukan di Laboratorium Entomologi Balai Penelitian Tanaman Pemanis dan Serat. Penelitian dilakukan secara eksperimental , dengan rangkaian acak lengkap (RAL). Uji toksisitas dilakukan dengan rangkaian uji pendahuluan, pemantapan, dan uji efek lanjutan. Dosis pestisida nabati minyak kemiri sunan 4,6% mampu menyebabkan mortalitas lebih dari 50% larva Crocidolomia binotalis Zell. Pertumbuhan dan perkembangan larva terganggu mulai dosis minyak kemiri sunan 3%. Minyak Kemiri sunan memiliki kecenderungan bertindak sebagai pestisida nabati yang bersifat racun kontak sekaligus antifeedan.
English Abstract
Crocidolomia binotalis Zell or commonly known as crop worm is the main pest of the Brassicaceae family of vegetables. Generally used synthetic insecticides in its control. Synthetic insecticides have the potential to cause resistance and increase residues in plants and have a negative impact on human health. One effort to reduce the use of chemical pesticides is to use plant-based insecticides. This study aims to analyze the effect and effective dose of sunan candlenut oil on mortality, growth, and development of crop worm (Crocidolomia binotalis Zell) as a vegetable pesticide. The study was conducted at the Entomology Laboratory of the Sweetener and Fiber Crops Research Institute. The study was conducted experimentally, with a complete random series (CRD). Toxicity tests are carried out with a series of preliminary, stabilization and follow-up tests. The dosage of 4.6% vegetable oil of Sunan Pecan Oil can cause mortality of more than 50% of the larvae of Crocidolomia binotalis Zell. The growth and development of the larvae were disrupted from the 3% dose of Sunan Pecan Oil. Sunan Candlenut Oil has a tendency to act as a vegetable pesticide which is both contact poison and antifeedant.
