The spur-throated locust can be readily distinguished from other pest species of locusts and grasshoppers by its large size and the presence of a spur between the front legs... Plagues of spur-throated locusts are less frequent than other pest species of locusts; migrations can occur into cropping areas... Once locusts have fledged or are 'flying', aerial spraying of agricultural chemicals is the only efficient method of control...

Locusts then migrate on prevailing weather systems, invading adjacent agricultural areas, including those in southern Queensland... The ability of locusts to invade previously uninfested areas and lay eggs within days, combined with the mobility of flying swarms, makes swarm control particularly difficult for individual landholders... The Australian Plague Locust Commission (APLC) will implement control measures only where the commission considers the locusts to be in sufficient numbers to present an interstate threat...

Unlike other grasshoppers, the usually shy locust can switch from a non-swarming (solitarious) phase, where it actively avoids other locusts, to a swarming (gregarious) phase depending on the density of locusts in their vicinity... After a few hours of crowding, locusts that were initially shy and solitarious will change behaviour to become gregarious locusts that form disastrous swarms of millions... Because social behaviour in so many animals depends on serotonin, if we used unspecific serotonin antagonists in the environment we run the risk of affecting other processes in locusts, as well as severely impacting animals other than locusts...
