High quality pest surveillance data is of key importance for retaining market access, both interstate and with international trading partners. Surveillance for specific pests is often carried out by state or territory departments of primary industries or independent parties. However, industry-driven surveillance is becoming an important tool in proving regional, area, or state freedom from pests of quarantine concern. The extent of surveillance that is necessary is highly specific to each importing country or state. Export approval can often depend on the major primary industries in that country, the importing country’s pest status and the level of assurance needed by that country to be confident about importing Australian produce.

The Pomewest Committee believe industry have identified the need to protect existing markets and gain new export markets. To achieve this Ashmere Consultants have been engaged to demonstrate that orchard surveillance programs capture pest numbers throughout the season and they also have documented pre and postharvest control measures in place to prove Area of Low Pest Prevalence (ALPP) trading status. A proactive Medfly surveillance program is both a useful pest control tool and insurance policy to maintain and gain markets for the Western Australian pomefruit industry.

As such the Surveillance Trapping Network Project has been funded over the past 2 years to develop a Surveillance for Medfly. The project commenced in 2015 with APC – Encouraging Producer Initiative APC Annual Report 2016 15 Medfly traps located in 12 grower orchards and 6 town properties in the south west of Western Australia. The first year of the project has targeted Donnybrook, Kirup, Manjimup and Pemberton with deployment of 168 Medfly traps that are checked and serviced each two to four weeks based on sound knowledge of the pest’s biology and ecology. The aim in the first year is to collect and collate Medfly baseline data from pome fruit properties in the area.

The project will determine Medfly numbers in key production areas and ensure continuation of surveillance and monitoring of the five year Medfly trapping program in the South West of Western Australia.

Update 2017

Pomewest continues to support this project and is making good progress to date. This surveillance is becoming an important tool in proving regional or state freedom from pests of quarantine concern. The data obtained to date showing low Medfly numbers in some orchards in Donnybrook, Kirup, Manjimup and Pemberton which will potentially support a future market access protocol but further research on establishment of buffer zones will be required.
