oa Journal of the Entomological Society of Southern Africa - Forecasts of incipient outbreaks of the brown locust
We have at our disposal detailed data on the life history of the brown locust, Locustana pardalina (Walk.). These data were obtained from cage experiments (Faure 1923 and 1932), and also from direct observations in the field (Smit 1939). Du Plessis (1938) undertook a detailed study of climatic conditions prevailing in the outbreak region from 1912 to 1937, and correlated these with the recent history of outbreaks, with a view to defining the conditions favourable for incipient swarming.
