| Abstract: | An analysis of the 1984 locust (Chortoicetes terminifera (Walker)) plague in Australia was undertaken to determine its source region using a simulation model of locust development and whether using appropriately enhanced satellite data, the individual areas that were suitable for locust breeding could be detected within this region. The origin of the 1984 plague was found to be in the Channel Country of south west Queensland, and satellite data indicated that there were localised areas suitable for locust breeding at the appropriate time other than those detected by ground survey. It is concluded that it isfeasible to use satellite data on an operational basis to detect areas suitable for locust breeding by monitoring changes in vegetation condition. Using the locust simulation model, the course of breeding and possible plague development can then be forecast, and ground surveys directed to the areas of interest at the approximate time. |
