Murray Local Land Services has warned that as temperatures rise, plague locust eggs laid over autumn and winter will begin hatching.
The young, wingless locusts, known as nymphs, often gather in dense groups called bands that appear black or dark in colour and move together across the landscape.
“Early reports of locust activity are critical, as locusts are most effectively managed during the nymph stage, before they develop wings and can travel long distances,” the latest Murray LLS update says.
“The first sign of nymph activity is expected across Murray, with hatching and banding anticipated between September 11 and 20.
“Landholders and community members are encouraged to keep a close watch on paddocks, pastures, cropping areas, roadsides and other open spaces for signs of locust activity.”
Experts say locust populations can build rapidly under favourable conditions, making early detection and reporting an important part of monitoring and management efforts across the state.
If you see locusts or signs of locust activity, report it within one business day to a Local Land Services biosecurity officer on 1300 795 299.
