  • Saat ini di Halmahera Utara petani sedang mengikuti program alih teknologi pertanian khususnya tanaman hortikultura.  Salah satu tanaman hotikultura yang dibudidayakan adalah kubis, akan tetapi dalam peningkatan produksi kubis mengalami permasalah organisme penggangu tanaman (OPT).  Spodoptera litura (F.) merupakan salah satu hama yang menyerang kubis. Serangan hama tersebut dapat menyebabkan kerusakan hingga 90 persen jika tidak dikendalikan. Salah satu cara mengurangi masalah akibat penggunaan insektisida sintetik yaitu perlu dikembangkan sarana pengendalian yang efektif dan ramah lingkungan  dengan menggunakan insektisida yang berasal dari tumbuhan (insektisida nabati).  Berdasarkan hal ini dilakukan penelitian mengenai efektivitas ekstrak buah bitung (Barringtonia asiatica L. ) terhadap hama Spodoptera litura F. Penelitian menggunakan Rancangan Acak Lengkap (RAL).  Perlakuan adalah konsentrasi ekstrak yaitu 10 persen, 20 persen, 30 persen, 40 persen, 50 persen, dan kontrol. Setiap perlakuan diulang sebanyak 5 kali. Hasil penelitian menunjukan bahwa pengendalian S. litura dengan menggunakan ekstrak B. Asiatica efektif.  Rata- rata mortalitas menunjukan hasil presentasi yang sangat baik.  Mortalitas tertinggi 84,25 persen ditemukan pada konsentrasi ekstrak 50 persen., dapat disimpulkan bahwa ekstrak buah efektif dalam mengendalikan larva S. litura. Saran perlu dilakukan penelitian lebih lanjut tentang efektifitas ekstrak  buah bitung dalam mengendalikan hama lain pada tanaman kubis bahkan hama pada tanaman sayuran lainnya.
