Locust Nymphs Detected Near Proserpine

Landholders Urged to Stay Alert

Biosecurity Queensland is urging landholders across the region to be on the lookout for locust activity, following the detection of late-stage nymphs in the Proserpine area.

The department is currently working closely with local landholders to identify the number and species of locusts present and to assist with control measures aimed at reducing the risk of a wider outbreak.

“Controlling locusts during the nymph stage is crucial,” a Biosecurity Queensland spokesperson said. “By breaking the lifecycle early, we can prevent large-scale infestations that could threaten crops and pasture across the region.”

There are four main species of locusts to watch for in Queensland — the Australian plague locust, migratory locust, spur-throated locust and yellow-winged locust. Landholders are encouraged to regularly inspect their properties for signs of these insects and report any sightings immediately.

Sightings can be reported by calling Biosecurity Queensland on 13 25 23, completing an online report, or emailing locustreports@dpi.qld.gov.au.

Under Queensland’s General Biosecurity Obligation (GBO), controlling locusts is primarily the responsibility of landholders. Nymphs can be effectively managed with approved insecticides before they develop into flying adults.

If infestations become too large for landholders to manage alone, the Department of Primary Industries will coordinate aerial spraying in partnership with the Australian Plague Locust Commission. This will be carried out responsibly, with buffer zones maintained around waterways and sensitive areas.
