Nilaparvata lugens merupakan salah satu hama penting bagi tanaman padi. Keberadaan Nilaparvata lugens pada tanaman padi dapat mempengarui produktivitas tanaman padi. Serangan dari Nilaparvata lugens dapat menyebabkan padi mengalami gagal panen. Pengaplikasian Lecanicillium lecanii pada padi efektif dalam mengendalikan hama wereng batang cokelat. Penggunaan Lecanicillium lecanii sebagai biopestisida yang ramah lingkungan dan tidak meninggalkan residu sehingga aman untuk digunakan. Penelitian dilaksanakan di Laboratorium Hama Tanaman Bagian Vertebrata Hama, Fakultas Pertanian, Universitas Gadjah Mada, Yogyakarta. Empat perlakuan A (Kontrol), B (Instar 1-2), C (Instar 3), dan D (Instar 4). Parameter yang diamati adalah presentase mortalitas dan Nilai LT50 jamur Lecanicillium lecanii terhadap nimfa Nilaparvata lugens. Hasil penelitian aplikasi Lecanicillium lecanii dapat menyebabkan mortalitas pada Nilaparvata lugens dengan Lt50 ±203 jam (instar 4-5). Lecanicillium lecanii efektif dalam mengendalikan setiap fase perkembangan Nilaparvata lugens namun tidak terdapat perbedaan pada nimfa instar 1-2, 3, maupun 4-5.

Nilaparvata lugens is one of the important pests for rice plants. The presence of Nilaparvata lugens in rice plants can affect their productivity of rice plants. Attacks from Nilaparvata lugens can cause the rice to experience crop failure. The application of Lecanicillium lecanii to rice is effective in controlling the brown planthopper pest. The use of Lecanicillium lecanii as a biopesticide is environmentally friendly and leaves no residue so it is safe to use. The research was conducted at the Vertebrate Pests Plant Pest Laboratory, Faculty of Agriculture, Gadjah Mada University, Yogyakarta. Four treatments namely A (Control), B (Instar 1-2), C (Instar 3), and D (Instar 4). Parameters observed were the percentage of mortality and the LT50 value of the fungus Lecanicillium lecanii against the nymph Nilaparvata lugens. The results of research on the application of Lecanicillium lecanii can cause mortality in Nilaparvata lugens with Lt50 ± 203 hours (4-5 instars). Lecanicillium lecanii was effective in controlling each developmental phase of Nilaparvata lugens but there was no difference in nymphs instars 1-2, 3, or 4-5.
