Liriomyza langei
leafminer
Liriomyza langei is a leafminer fly species in the family Agromyzidae, first described by Frick in 1951. The species is known as a significant agricultural pest, particularly of chrysanthemum and spinach crops. Larvae feed internally within leaf tissue, creating characteristic mines that reduce photosynthetic capacity and crop quality. The species has been the subject of biological control studies using the parasitoid wasp Diglyphus isaea, as well as genetic research on host plant resistance in spinach.
