sustainability through science & innovation
We have received a report of Australian plague locusts (Chortoicetes terminifera) hatching near Kerang, in the Northern Country district of Victoria. Very high numbers of early instar nymphs were found on a roadside adjacent to a lucerne paddock. This follows earlier reports of hatchings around Swan Hill and Mildura, both in the Mallee district of Victoria, as well as hatchings in some regions of South Australia, and widespread hatchings in New South Wales.
Growers and agronomists in regions where locust egg beds have been identified should now be keeping a close eye out for young locusts. Predicted peak hatching dates are available on the APLC website. Upon hatching, Australian plague locusts are only about 4 mm long, and are generally pale brown in colour. They progress through 5 nymphal instars before becoming adults. This typically takes 4 - 6 weeks. To be most effective, it is important that control efforts target locusts when they form high density ‘bands’, generally as second and third instar stages.
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.
