Abstract

Leafminer fly, Liriomyza spp. are widely known as new important pests attacking many vegetable species in high land in Indonesia. The objective of the research was to study community of parasitoid leafminer in high altitude, and parasitization level. This research also looked at more specific on parasitization level caused by Opius chromatomyiae. There were four species of leafminer recorded from the survey, Liriomyza huidobrensis, Liriomyza sativae, Liriomyza chinensis and Chromatomyia horticola. The observation also found eight species of parasitioid associated with collected leafminers. Six species of recorded parasitoid belonged to family of Eulopidae, and two rest species belonged to Braconidae and Eucoilidae respectively. Those eight species of parasitoids were Hemiptarsenus varicornis, Asecodes de/uchii, Neochrysocharis okazakii, Neochrysocharis formosa, Neocrhysocharis sp. Quadrastichus firiomyzaeJ Opius chromatomyaie, Gronotoma micromorpha. Parasitoid Opius chromatomyiae and Hemiptarsenus varicornis were found to be dominant in the range altitude between 1001-1300 and 1:;01-1600 asl. From 16 spesies of hosts attacked by leaf miners, only Opius chromatomyiae was recorded to have ability to parasitize the leafminer in 13 host species with parasitization level reached 1,84- 62,26%.
