Abstract EN
Liriomyza chinensis is a major pest of Welsh onion Allium fistulosum in Asia but little is known about the abundance of its natural enemies.
A field survey was made to explore the major parasitoids of L.
chinensis leaf miner in central Vietnam.
An eulophid parasitoid, Neochrysocharis okazakii, comprised more than 95% of parasitoids reared from leaf miner larvae collected in the onion field and 98.3% of leaf miner parasitoids found during searches of onion plants.
The mean number of female N.
okazakii on plants was greater in onion fields with a higher density of L.
chinensis, and, during searches, a greater proportion of N.
okazakii was found on onion with more L.
chinensis mines, suggesting density-dependent parasitoid aggregation.
Melanized dead larvae of L.
chinensis were more frequently found in onion fields with more parasitoids, demonstrating that melanized leaf miners are a good indicator of parasitoid activity.
Mean instant rate of host encounter by N.
okazakii in the field was estimated at 0.077, and the likelihood of a parasitoid finding a host increased with host density.
Taken together, these results show that N.
okazakii is the major parasitoid of L.
chinensis.
Usefulness of this parasitoid in stone leek leaf miner management is discussed.
