ABSTRAK

Kutu putih pepaya Paracoccus marginatus (Hemiptera: Pseudococcidae) di Indonesia dilaporkan menyerang pepaya tahun 2008 di Bogor. Di  Sulawesi Utara dilaporkan menyerang pepaya tahun 2009 di Manado. Tujuan penelitian untuk mengetahui penyebaran dan tingkat serangan kutu putih pepaya P. marginatus di Sulawesi Utara. Penelitian dilakukan mulai Desember 2010 - September 2011. Data penyebaran kutu putih pepaya didasarkan pada ketinggian tempat di Sulawesi Utara, yaitu : Bitung, Minahasa Utara, Minahasa, Minahasa Tenggara, Minahasa Selatan, Tomohon, dan  Manado. Tanaman pepaya yang terserang dilihat intensitas serangan yaitu serangan ringan < 25 %, sedang  25-50 % dan berat 50-90 %. Sampel tanaman yang terserang  kutu putih pepaya dan musuh alami dibawa di laboratorium Hama dan Entomologi, Fakultas Pertanian Unsrat Manado untuk diidentifikasi. Hasil penelitian menunjukkan hama kutu putih pepaya telah tersebar di beberapa perkebunan  pepaya di Sulawesi Utara. Serangan kutu putih pepaya meliputi beberapa daerah di dataran rendah (< 200 m dpl) sampai di daerah tinggi (800 m dpl).
