“…Locusts with multivoltine life cycles such as Australian plague locust, Chortoicetes terminifera (Walker) ( Wright 1987; Hunter 1996), the desert locust, Schistocerca gregaria (Forskål) ( Pedgley 1981) and the South American locust, Schistocerca cancellata (Serville) ( Hunter & Cosenzo 1990) can have three to four generations in a year and reach plague proportions within a year or so. However, the univoltine life cycle of A. guttulosa means it takes several years for many swarms to be produced.…”

In northern Australia, the spur‐throated locust, Austracris guttulosa, has one generation per year with locusts surviving the dry season as immature adults. Adults lay after rain early in the wet season, mainly between October/November and January. On cracking clay soils, a fall of > 40 mm is required to allow oviposition, but to ensure survival of the resulting offspring, there must be follow‐up rain of > 40 mm at the oviposition site within 6 weeks. Populations increase during years when more than 50% of the arid zone and Gulf receive both initial and two or more follow‐up rains at intervals of ≤ 6 weeks. During the 1970s and 1990s, there were two periods of 3–5 years of such increase, and a large number of swarms resulted.

A national research approach to the ?grasshopper problem' began following a plague of the Australian plague locust (Chortoicetes terminifera Walker) in inland south-eastern Australia in the 1930s. After the plague of the 1950s, the role of arid inland areas as a source of migrations into agricultural areas received greater attention. In the 1960s and 1970s, international collaborative experimental research with the CSIRO advanced the knowledge of locust lifecycles and population ecology. Studies of nocturnal mass migration on upper-level winds brought a new understanding of Australian locust population dynamics. This paper traces Australian research into locust ecology within the contexts of locust infestations and government responses to them. Investigations on Australian locusts reflected many contemporary ideas and methods in entomological research and contributed to the development of international ecological theory during the twentieth century. International locust research based on the phase change and outbreak area model of Uvarov particularly influenced work carried out in Australia.
