oa Journal of the Entomological Society of Southern Africa - Recent outbreaks of the brown locust, Locustana pardalina (Walk), with special reference to the influence of rainfall

Volume 21, Issue 1
  • ISSN : 0013-8789



This paper is essentially a continuation of the work of du Plessis (1938) who reviewed the history of brown locust outbreaks in South Africa from 1910 to 1938/39 and attempted at the same time to correlate them with fluctuations in the rainfall over the main outbreak areas. The present study covers a period of fourteen years from 1941l/42 to 1954/55 during which the brown locust increased from a very low level of infestation to a peak year of swarming in 1950/51 and finally became reduced to relatively small numbers again in 1954/55.
