Vegetable Leafminer is a very small black and yellow fly (1-2 mm in length). Female flies lay eggs inside leaves and stems. Maggots tunnel inside the leaf and make visible tracks that get wider as they grow. Leaf mines interrupt the photosynthetic ability of plants, can lead to secondary infection, and reduce marketability of produce. The fly, which is prone to developing resistance to a range of insecticides, has a very broad plant host range that includes beans, pumpkins, eggplant, capsicum, cabbage, lettuce, cauliflower, cucumber, zucchini, potato, cole crops, and a range of ornamentals including Allium, Aster, Dahlia, Phlox, plus Solanaceae including tomato.
MT16004 – RD&E Program for control, eradication and preparedness for Vegetable Leafminer (2017-2020) was developed in recognition of the extensive impact that Vegetable Leafminer could have on the vegetable and nursery industries were it to move into production areas with no management plan in place. Project partners include cesar, the University of Melbourne, Plant Health Australia, NAQS, AUSVEG and NGIA.
From now until 2020 the project will prepare for the potential spread of the pest by:
- Investigating biological and chemical control options;
- Identifying spread pathways into Australia;
- Developing management guidelines and trapping methods;
- Modelling the spread of the pest from Cape York Peninsula; and
- Developing a contingency plan and response plans in the event of a regional eradication.
