Abstract: The orange spiny whitefly (OSW), Aleurocanthus spiniferus (Quaintance) (Homoptera: Aleyrodidae) is one of the relatively new pests of citrus in the Republic of Palau. It is a problem on citrus trees and rose plants in home gardens. The leaves, fruit and branches of infested trees are generally covered with sooty mold. Also decline in vigor and yield was observed in infested trees. Surveys were conducted to assess the distribution and population density of A. spiniferus and the occurrence of parasitoids in Palau. The number of citrus trees examined for OSW was 59 citrus trees in Koror, 41 in Babeldaob, 25 in Angaur, 14 in Kayangal and 30 in Peleliu. The islands of Angaur and Kayangel were free of A. spiniferus while Koror, Babeldaob and Peleliu were infested. This whitefly was observed in almost all parts of the island of Koror, in the village of Klauklu in Peleliu and in the States Airai, Aimeliik, Ngatpang (Ibobang), Melekeok, Ngiwal, and Ngarchelong in the island of Babeldaob. The parasitoids, Encarsia aseta Hayat and Polaszek (Hymenoptera: Aphelinidae) and Amitus sp. (Hymenoptera: Platygastridae) have been collected from Koror, E. aseta has been collected from Babeldaob, and none from Peleliu. Percent parasitism from collected samples varied from 0 to 42%.
