Identification and Population Abundance of Leaf Miner (Liriomyza spp.) (Diptera: Agromyzidae) on Onion Plant (Alium ascalonicum L.) and WelshOnion (Allium fistolosum L.) This research was conducted in order to determine the species and abundance population of leaf miner which attacked the onion plant (Alium ascalonicum L.) andwelsh onion (Allium fistolosum L.). The sample in this research was taken by purposivemethod by taking 100 leaves per species of onion in Bangli and Tabanan Regencies.The leaf sample was reared in a bottle container and the emerged adult insects of theleaf miner were identified morphologically. The results showed the leaf miner speciesthat attacked onions plant and welsh onion were Liriomyza chinensis and Liriomyzahuidobrensis. The leaf miner species found on onion plant in Songan Village, BangliRegency was L. chinensis with an abundance of 100% (324 adult insects). Meanwhile,in Batusesa Village, Tabanan Regency, which is the center of welsh onion production,two species of leaf miner were found, namely L. chinensis and L. huidobrensis withan abundance of L. chinensis 97.0% (258 adult insects) and L. huidobrensis 3.0% (8adult insects). In generally, L. chinensis is a species of leaf miner which dominate theonion plantations.
