The Northern Territory Department of Industry, Tourism and Trade is increasing plant surveillance after a confirmed single sample of American serpentine leafminer (Liriomyza trifolii) was found in the Katherine region.

There have been multiple detections of American serpentine leafminer (ASLM) in far-north Queensland’s Torres Strait and in Kununurra, Western Australia.

ASLM poses a significant economic impact to Australia’s plant production industries. It has a wide host range including beans, celery, cucumber, lettuce, potato, tomato and many more.

The pest is spread through the movement of plant material, soil, clothing and equipment.

Leaf damage by ASLM occurs through puncture wounds from the adult feeding and laying eggs. Damage is also caused by larvae tunnels or leaf mines within the leaf tissue.
