Jagung (Zea mays saccharata Sturt) merupakan sumber pangan kedua setelah padi, yang kebutuhannya selalu meningkat setiap tahunnya. Kendala dalam budidaya jagung salah satunya adalah hama, yang menyerang tanaman jagung selama masa pertumbuhannya dari fase bibit sampai fase generatif. Penggunaan pestisida untuk pengendalian hama dapat membahayakan kesehatan baik pada manusia maupun lingkungan. Pengendalian Hama Terpadu (HPT) dilakukan melalui penanaman refugia berbunga di sekitar pertanaman jagung serta aplikasi kerapatan konidia jamur entomopatogen Fusarium oxysporum sebagai alternatif dari pestisida. Penelitian dilaksanakan pada November - Februari 2024 di Lahan Pasir Kulon, Kecamatan Karanglewas, Kabupaten Banyumas, dan Laboratorium Perlindungan Tanaman Universitas Jenderal Soedirman, Purwokerto. Penelitian dilakukan dengan Rancangan Tersarang menggunakan 2 faktor. Faktor sarang merupakan refugia berbunga yaitu B0 = kontrol; B1 = Cosmos sulphureus; B2 = Turnera subulata; B3 = Helianthus annuus; dan B4 = Zinnia sp. Faktor tersarang merupakan kerapatan konidia Fusarium oxysporum dengan 3 taraf yaitu F0 = kontrol; F1 = kerapatan 106; dan F2 = kerapatan 108. Data dianalisis dengan uji analisis ragam apabila terdapat beda nyata, dilanjutkan dengan Duncan’s Multiple Range Test (DMRT). Hasil penelitian menunjukkan perlakuan H. annuus memberikan rerata keanekaragaman serangga hama tertinggi dan rerata indeks dominansi terendah. Perlakuan Zinnia sp. mampu menekan intensitas serangan hama hingga 8 – 33%. Petak kontrol memberikan intensitas serangan hama tertinggi dan hasil produksi bobot tongkol per petak terendah.

Corn (Zea mays saccharata Sturt) is the second food source after rice, with its demand increasing every year. One of the obstacles in maize cultivation is pests, which attack maize plants during their growth period from the seedling phase to the generative phase. The use of pesticides for pest control can endanger the health of both humans and the environment. Integrated Pest Management (IPM) is carried out through the planting of refugia plants around corn fields and the application of conidia density of the entomopathogenic fungus Fusarium oxysporum as an alternative to pesticides. The research was conducted from November to February 2024 at Lahan Pasir Kulon, Karanglewas District, Banyumas Regency, and the Plant Protection Laboratory of Jenderal Soedirman University, Purwokerto. The research was conducted using a Nested Design with 2 factors. The nesting factor was flowering refugia, namely B0 = control; B1 = Cosmos sulphureus; B2 = Turnera subulata; B3 = Helianthus annuus; and B4 = Zinnia sp. The nested factor was the conidia density of Fusarium oxysporum with 3 levels, namely F0 = control; F1 = density 106; and F2 = density 108. Data were analyzed using analysis of variance (ANOVA) if there were significant differences, followed by Duncan’s Multiple Range Test. (DMRT). The research results show that the treatment with H. annuus provided the highest average insect pest diversity and the lowest average dominance index. The treatment with Zinnia sp. was able to reduce the intensity of pest attacks on corn crops by 8 – 33%. The control plot showed the highest pest attack intensity and the lowest ear weight production per plot.
