Pertanaman pepaya di Kabupaten Toraja Utara, Kabupaten Gowa Sulawesi Selatan dan Kabupaten Mamasa Sulawesi Barat menunjukkan gejala mosaik yang berat pada bagian daun. Penelitian ini bertujuan untuk mengetahui kisaran inang virus penyebab penyakit mosaik pada tanaman papaya berdasarkan gejala penyakit. Dalam penelitian ini menggunakan sampel daun tanaman pepaya yang bergejala mosaik dan variasi gejala lainnya dikumpulan dari beberapa tempat pertanaman pepaya di Kabupaten di Sulawesi Selatan dan Sulawesi Barat. Propagasi virus pada tanaman dilakukan dengan melakukan metode sap-inoculation. Keberadaan penyakit mosaik dan tanaman sakit dideteksi dengan kajian biologi yakni pengujian pada tanaman inang indikator. Hasil pengujian respon tanaman indikator terhadap 25 isolat virus mosaik secara mekanik memperlihatkan 19 isolat virus yang dapat menginfeksi kelima tanaman indikator dengan persentase penularan dan lama periode inkubasi virus berbeda-beda.
Kata Kunci : pepaya, virus mosaik, kisaran inang
