The Australian plague locust is a particularly attractive target given that control is often directed at nymphs which occur in high density bands with very sparse cover of vegetation. This occurs via a preventative control strategy involving ultralow-volume spray equipment to distribute small droplets of control agent over a target area. Plague locusts lay dormant during poor seasons and crop up in bumper ones The Australian plague locust species, if not controlled, can cause significant damage to crops and pastures by consuming .
