A 2-year study was conducted on the population density of adults, larvae, extent of damage, and larval parasitoids of the onion leafminer (LM) Liriomyza trifolii (Burgess) in weekly-sprayed and unsprayed onion fields in Bongabon, Nueva Ecija, Philippines. The area is known for large-scale cultivatio...
