Tomato Leafminer Fly (Liriomyza bryoniae)
Leafmining fly causing serpentine tunnels in tomato and related crops.
Tomato leafminer fly (Liriomyza bryoniae) is a common leafmining pest in tomato, cucumber and other protected crops. Adults puncture leaves to feed and lay eggs; larvae create serpentine mines that reduce photosynthesis and act as entry points for disease. Biological control uses parasitoid wasps such as Diglyphus isaea and Dacnusa sibirica, introduced preventatively or at the first sign of mines. Hygiene and removal of mined leaves support successful control.
