Density distributions of hoppers of the Red Locust, Nomadacris septemfasciata (Serv.) (Orth., Acrid.), in relation to control by insecticides
Bulletin of Entomological Research 49 (3), 467-478
Abstract: Population distribution of Nomadacris septemfasciata in a 1052-acre area in the Rukwa Valley outbreak area was studied in relation to the adoption of rational control measures and swarm formation. Observations were made from 18 January to 24 February, 1957. Densities were mostly under 50 per sq. yd. and the mean density in bands was 15 per sq. yd. The total population of about 4½ million remained more or less constant. There was a tendency for bands to fuse and the area free from locusts to increase slightly although the number of dispersed locusts increased. In this case, holding back insecticide control in the hope of attacking denser and more economical targets would not have been advantageous.
