Due to the continuing warm weather in some parts of the State, Australian plague locust (APL) adults are still active.

APL activity has been reported over a wide area of the grainbelt, from as north as Eneabba and south to Scaddan (see reported locations above).

Growers from Mukinbudin and Eneabba have reported APL causing damage to crops, with some crops in Mukinbudin needing to be re-sown.

Even though APL activity is expected to decrease with cooler weather, insecticide control needs to occur if crops are being damaged. The best time to apply insecticide is early in the morning when APL are not actively moving. For more insecticide information, visit DPIRD’s Australian plague locust control: registered insecticides page.

The PestFax team would appreciate growers and consultants continuing to report APL activity this season by using the PestFax Reporter app.

To read about previous APL activity reported this season, refer to the 2021 PestFax Issue 1 article, Locusts can damage emerging crops.

Further APL information can be found at DPIRD’s Australian plague locust overview page.
