Abstract

Identification and Population Abundance of Leaf Miner (Liriomyza spp.)
(Diptera: Agromyzidae) on Onion Plant (Alium ascalonicum L.) and Welsh
Onion (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.) and
welsh onion (Allium fistolosum L.). The sample in this research was taken by purposive
method 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 the
leaf miner were identified morphologically. The results showed the leaf miner species
that attacked onions plant and welsh onion were Liriomyza chinensis and Liriomyza
huidobrensis. The leaf miner species found on onion plant in Songan Village, Bangli
Regency 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 with
an abundance of L. chinensis 97.0% (258 adult insects) and L. huidobrensis 3.0% (8
adult insects). In generally, L. chinensis is a species of leaf miner which dominate the
onion plantations.
