Abstract

Hama padi merupakan masalah yang menuntut untuk ditangani secara efektif, mudah, dan murah. Penggunaan pestisida sebagai solusi terbukti membawa dampak negatif sehingga perlu dikembangkan inovasi pengendalian hama, salah satunya adalah refugia. Refugia jagung dan kacang panjang menjadi salah satu solusi terbaik dalam berbagai aspek. Penelitian ini bertujuan untuk mengetahui kelimpahan, struktur komunitas, dan diversitas serangga di lahan persawahan padi di Desa Tunjungtirto, Kecamatan Singosari, Kabupaten Malang. Metode yang digunakan adalah visual kontrol terhadap serangga pengunjung blog refugia. Pengambilan data dilakukan sebanyak tiga kali sehari pada fase vegetatif dan generatif tanaman refugia selama 15 menit. Hasil penelitian menunjukkan bahwa tanaman refugia di sawah padi dapat menyeimbangkan populasi serangga herbivora, predator, dan polinator. Dibuktikan dengan persentase kelimpahan relatif herbivora yang lebih rendah. Struktur komunitas di sawah dengan refugia lebih seimbang, INP menunjukkan bahwa family Acrididae (56,66%) memiliki peran yang penting dalam ekosistem sawah, dan Indeks Diversitas Shanon-Winner menunjukkan diversitas yang lebih beragam dibanding sawah tanpa refugia. ABSTRACT Insect pests of rice is a problem that demands to be handled effectively, easily, and inexpensively. The use of pesticides as a solution proven to have negative impacts thus it is necessary to develop the innovation to manage pests, one of which is refugia. Refugia of corn and beans to be one of the best solutions in various aspects. This study aims to determine the abundance, community structure, diversity of insect visitors of refugia in the rice paddy fields in Village Tunjungtirto, Singosari, Malang regency. The method used is the visual encounter surveys against insects. Data retrieval was performed three times a day on the phase of vegetative and generative plant refugia for 15 minutes. The results showed that the plant refugia in paddy fields can balance the population of insect herbivores, predators, and pollinators. This was evidenced by the percentage of relative abundance of herbivorous was lower in paddy field with refugia. Community structure in the rice fields refugia was more balanced, IVI (important value index) showed that the family Acrididae (56,66%) have an important role in the ecosystem of rice fields. The diversity of insect in that with refugia was greather than that without refugia.
