Three new species of Liriomyza leafminer flies are now present in Australia:

• American Serpentine Leafminer (ASLM (Liriomyza trifolii))
• Serpentine Leafminer (SLM (Liriomyza huidobrensis))
• Vegetable Leafminer (VLM (Liriomyza sativae))

These pests all feed on many plants and will likely affect most commercial crops (including many vegetable crops). Damage on some commercial crops has been recorded from Qld, NSW, NT, WA and Vic.

Experience from other countries shows us that overuse of chemical controls will backfire. IPM approaches are the most likely to be successful in managing these insects.

AUSVEG has produced a series of grower guides on best practice management of American serpentine leafminer, serpentine leafminer, and vegetable leafminer. These guides are available in English, and have been translated into Vietnamese, Simplified Chinese and Arabic.
