Introduction. In New South Wales, three species of locust are declared pest insects under the Local Land Services Act These are: Australian plague locust (Chortoicetes terminifera)migratory locust (Locusta migratoria)spur-throated locust (Austracris guttulosa).All three of these species can cause significant damage to pastures and crops, but the Australian plague locust occurs the most. The Australian Plague Locust, Chortoicetes terminifera, is a native Australian insect. It occurs naturally in the far north west of New South Wales and adjacent areas of Queensland and South Australia, an area known as the channel country. The Australian plague locust (Chortoicetes terminifera) regularly forms migratory bands and swarms, but is claimed not to express phase polyphenism and has accordingly been used to argue against a. Several species of grasshoppers swarm as locusts in different parts of the world, on all continents except Antarctica and North America: For example, the Australian plague locust (Chortoicetes terminifera) swarms across Australia.. The desert locust (Schistocerca gregaria) is probably the best known species owing to its wide distribution (North Africa, Middle East, and Indian subcontinent) and.
The Australian plague locust hopper (left) showing the typically saddle-shaped body profile, compared to the Australian wingless grasshopper (right) body profile, which is more straight The best field identification of locusts at the hopper stage of development is the X-shaped marking on the back of their thorax. Individuals may migrate large distances (hundreds of kilometres) in dense swarms at night. During the day, swarms of flying adults or bands of hoppers move and devour crops and pastures in their path. The bands of hoppers develop from nymphs from dense egg beds. Swarms of Australian Plague Locusts occur more frequently than the Migratory Locust. In the Australian plague locust, Chortoicetes terminifera, stimulation of the antennae, but not the hindlegs, is sufficient to elicit a phase transition (Cullen et al., ). Not only tactile. 1. Introduction. The Australian plague locust, Chortoicetes terminifera (Walker), is a recurrent pest of agriculture in Australia. Typically short periods with few locusts are followed by frequent outbreaks (Wright, ; Hunter, ) when substantial numbers of locusts can cause significant crop damage (Wright, ).Locusts can breed both in the arid interior and in the agricultural zone to Cited by:
The Australian plague locust, Chortoicetes terminifera (Walker) (Orthoptera: Acrididae), infests most of the interior of eastern Australia. In this paper the population dynamics of C. terminifera and its behaviour in relation to control are outlined.

A high-density swarm (more than 50 insects per m 2) of Australian plague locusts covering 2km 2 will contain around 1 billion insects, which can eat 20 tonnes of vegetation a day. Locusts at both nymph and adult stage can cause extensive crop and pasture damage.
