Have you ever seen the Leaf miner? [AusVeg]

Script by AusVeg, (great one! I've learnt so much about this leafminer working on this). Tourism and trade is increasing the risk of exotic pests being transported around the globe. Airports, seaports, and tourism hotspots are high risk entry points for pests. Agromyzid flies are one such group of agricultural pest that are now found in many parts of the world. This includes the Vegetable Leafminer, which is a recent arrival to Australian shores. Between 2008 and 2015 the Vegetable Leafminer was detected on multiple islands in the Torres Strait by the Northern Australian Quarantine Strategy. In 2015 the Vegetable Leafminer was found on Cape York Peninsula, the most northerly point of the Australian mainland. This is a concern because the Leafminer can have a dramatic impact on plant health. Eggs are laid just beneath the leaf or stem surface and hatch about three days later. Once hatched, larvae tunnel inside the leaf creating silvery, spiralling tracks. These ‘leafmines’ damage photosynthetic tissue, restricting plant growth. Once enough plant is consumed, larvae develop into pupae, and emerge as an adult leafminer. At about 1-2 mm in length, the most striking feature of adult Vegetable Leafminer are areas of bright yellow cuticle on the head, upper and lower body. The Vegetable leafminer is polyphagous, which means that most horticultural crops are on the menu. It will eat most vegetables and even some ornamental flowering plants that you can pick up at your local nursery, such as snap dragon and petunia. The Leafminer diet may also extend to other crops that are not currently listed as a host. So, what does all of this mean, and what’s at stake? Australian horticulture is currently valued at $9 billion. When we find a new pest in Australia, the economic damage to production industries can be catastrophic. Farmers can experience trade bans, production losses and quarantine. This means that fresh produce doesn’t reach store shelves. Everybody loses! So what are we doing about it? The vegetable industry, and nursery and gardens industry encompass many horticultural commodities that may be impacted by the Vegetable Leafminer. Recognising the potential impact of this pest the grower owned Research & Development Corporation, Hort Innovation, recently launched a program for control, eradication and preparedness for the Vegetable Leafminer. This project is all about being prepared and it brings together research groups, governments, and industry bodies. Project partners will figure out best methods of trapping for Vegetable Leafminer, investigate how the leafminer is spreading to Australia, and model where the pest may spread in future. The project will result in a contingency plan that will guide industry and government in a plan of action if the pest is found in production zones and a management plan that will be structured around an Integrated Pest Management approach. By becoming acquainted with this exotic pest now, and raising awareness about the Vegetable Leafminer with growers, councils, and the public we will slow its spread or even eliminate it from Australia altogether. Australia is renowned for producing high quality fresh produce. To keep it that way, we need to stay vigilant. Vegetable Leafminer damage may be confused with that of the Cabbage Leafminer or Chrysanthemum Leafminer. You are likely to be alerted to Vegetable Leafminer damage if leafmining is observed on a diversity of plants. All Australians have a biosecurity responsibility. Suspect detections should be reported to the Exotic Plant Pest Hotline on 1800 084 881. Together we can keep Australia free of the Vegetable Leafminer.
