sustainability through science & innovation
Planning is continuing for what is expected to be a serious widespread infestation of Australian plague locusts (Chortoicetes terminifera) in New South Wales, northern Victoria and eastern South Australia in spring. The Australian Plague Locust Commission (APLC) has published predicted locust hatching and development dates for a list of locations likely to be affected by locusts. The most recently published dates have been modified to reflect temperatures recorded over the last decade rather than long-term averages, with the expectation that spring 2010 temperatures are likely to exceed 20th Century averages by approximately one degree.
Although these dates should be used as a guide, it is important to note that hatching will be distributed over a period of several weeks and the exact timing will depend on local conditions and temperatures in late winter and early spring. Landholders need to be vigilant and remain on the lookout for locust egg hatchings. It is also critical that landholders in areas expected to be affected by locusts are well organised and have a plan in place to manage their situation.
The Grains Research and Development Corporation have released a Plague Locust Control fact sheet. This document includes a table of predicted locust hatching and development dates, a map detailing locust risk zones, useful contact details for each state, and information on chemicals with registration or APVMA permits for locust control.

What is PestFacts?
PestFacts south-eastern keeps growers and advisers informed about invertebrate pests and beneficials in broadacre crops and pastures during the winter-cropping season in Victoria and southern New South Wales.
PestFacts south-eastern is run through IPMforGrains: Best Practice Insect Pest Management, a project delivered by the National Pest Information Network (cesar, DPIRD, QDAF, NSW DPI, and SARDI). This project aims to provide grain growers and advisors with information on invertebrate grain pest occurrence and equip industry with the knowledge needed to implement integrated pest management practices. This initiative is a GRDC investment and includes in-kind contributions from all project partner organisations.
We need your reports
PestFacts is produced on an ʻas-needsʼ basis and relies upon pest observations and field reports from our subscribers. If you have recently observed invertebrate pests (or beneficial species) in broadacre crops, please contact us to report your observations.
Agricultural invertebrate identification
If you are a grower or agronomist in Victoria or NSW working with broadacre crops or pastures, we can assist you with identifying invertebrates found on farms at no cost. Please contact us for identification help.
PestFacts map
PestFacts map is an interactive tool that allows users to search and view historical pest reports across Victoria and NSW. The map is updated with each issue of PestFacts to include new reports.
