Abstract

ABSTRACT
The objective of this work was to study the distribution and state of the new and accidentally introduced
insect pests of papaya and pakis haji in North Sulawesi. Results showed that the papaya mealy bug,
Paracoccus marginatus (Hemiptera: Pseudococcidae) has spread and establised in North Sulawesi but
its level of infestation has been from low to medium depending on the location. The main natural
enemies found on the papaya mealy bug were Coccinelidae (Coleoptera), Hermetia illucens (Diptera:
Stratiomyidae) and Acerophagus papaya (Hymenoptera: Encyrtidae). The Cycad scale, Aulacaspis
yasumatsui Takagi (Hemiptera: Diaspididae) and yellow beetle, Lilioceris sp. (Coleoptera:
Chrysomelidae) were first recorded on pakis haji in North Sulawesi and causing damage to pakis haji in
this region. The predator found on cycad scale was a beetle, of the famili Cybocephalidae genus
Cybocephalus.
