The purpose of this study is to find out distribution and the host range of mealybug Paracoccus marginatus and their attack intensity in the field, especially in the centers of papaya cultivation in the North Minahasa region, North Sulawesi Province, Indonesia. The study uses a survey method conducted in four villages, namely: Matungkas, Laikit, Dimembe and Tetei. Sampling was done by purposive sampling. Sampling was carried out in three fields per village that had different cropping systems on the farms cultivated by farmers. Each location was sampled and observations were made on papaya plants to see whether papaya mealybug were attacked or not attacked. Samples of mealybug and host plants from the field were brought to the laboratory for identification. The results showed the attack intensity of mealybug ranged from 13.67% to 60%.Symptoms of mealybug attack on papaya plantations was variated from the symptoms of low intensity to high intensity. The results of this research found host plants of P. marginatus consisted of seven species of plants, besides papaya namely: Annnona muricana, Persea gratissima, Codiaeum spp, Aglonema spp, Anthurium spp, Hibiscus spp. and Jatropha spp.
