| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mempelajari metabolit sekunder empat jamur entomopatogen terhadap mortalitas kutu kebul, intensitas penyakit akibat virus, serta korelasi kedua variabel. Penelitian dilaksanakan pada bulan Oktober 2018 sampai Mei 2019 di laboratorium Perlindungan Tanaman dan screen house Fakultas Pertanian, Universitas Jenderal Soedirman. Rancangan percobaan in- vitro adalah Rancangan Acak Kelompok dan percobaan in- planta adalah Rancangan Bujur Sangkar Latin. Pada uji mortalitas in-vitro hama B. tabaci terdiri atas 5 perlakuan (metabolit sekunder Beauveria bassiana Papua, B. bassiana Jember, Metarhizium anisopliae, Lecanicillium lecanii; dan kontrol) dan diulang 5 kali. Uji indeks kitinolitik terdiri atas 4 perlakuan diulang 4 kali. Uji in planta terdiri atas 5 perlakuan diulang sebanyak 5 kali, setiap unit percobaan terdiri atas 3 tanaman. Variabel yang diamati adalah mortalitas imago, indeks kitinolisis, masa inkubasi, intensitas penyakit, tinggi tanaman dan jumlah daun. Hasil menunjukkan semua perlakuan metabolit sekunder jamur entomopatogen menyebabkan mortalitas pada imago B. tabaci masing- masing sebesar 77,8% (B. bassiana Papua); 71,5% (B. bassiana Jember); 66,7% (M. anisopliae); dan 59,5% (L. lecanii). Semua metabolit sekunder jamur entomopatogen menurunkan intensitas penyakit akibat virus masing- masing sebesar 79,98% (B. bassiana Papua); 74,00% (B. bassiana Jember); 72,23% (L. lecanii); dan 55,41% (M. anisopliae). Korelasi antara mortalitas hama B. tabaci akibat perlakuan metabolit sekunder jamur entomopatogen dengan intensitas penyakit akibat virus sangat erat dan berkebalikan. Setiap peningkatan 1% mortalitas hama menyebabkan penurunan intensitas penyakit akibat virus sebesar 1,346%. |

| Abtrak (Bhs. Inggris) | The aim of this research was to study the secondary metabolites of four entomopathogenic fungi against whitefly mortality, viral disease intensity and correlation between the two variables. The research was conducted from Oktober 2018 to May 2019 in the Plant Protection Laboratory and the screen house of Faculty of Agriculture, Jenderal Soedirman University. The in-vitro test used randomize completely design consisted of five treatments (secondary metabolites of Beauveria bassiana Papua and Jember isolates, Metarhizium anisopliae, Lecanicillium lecanii and control) and repeated five times. The in-planta experiment used latin square design consisted of five treatments and repeated five times. Variables observed were mortality of whitefly imago, chittinolytic index, incubation period, viral disease intensity, plant height and total leaf per plant. The results showed that all treatment of secondary metabolites of entomopathogenic fungi caused mortality in the B. tabaci imago by 77.8% (B. bassiana Papua); 71.5% (B. bassiana Jember); 66.7% (M. anisopliae); and 59.5% (L. lecanii). All secondary metabolites of entomopathogenic fungi reduce the intensity of viral diseases by 79.98% (B. bassiana Papua); 74.00% (B. bassiana Jember); 72.23% (L. lecanii); and 55.41% (M. anisopliae). The correlation between B. tabaci pest mortality due to the treatment of secondary metabolites of entomopathogenic fungi with the intensity of disease due to viruses is very close and opposite. Every 1% increase in pest mortalitycausing decrease in the intensity of viral diseases by 1,346%. |
