The effect of climate and weather on the numbers of the Red Locust, Nomadacris septemfasciata (Serv.), in the Rukwa Valley outbreak area
Bulletin of Entomological Research 50 (3), 507-521
Abstract: A very high level of Lake Rukwa, Tanganyika, is correlated with small numbers of Nomadacris septemfasciata. When the lake level is low, the size of adult locust populations in the dry season is related to the rainfall of the last but one wet season, the size of the preceding parental population and the rainfall of the preceding October-December, but not to the date of the drop in temperature associated with the start of ovarian development. The possibility of forecasting the size of the adult population on the basis of these correlations in time for hopper control is discussed.
