oa Journal of the Entomological Society of Southern Africa - Observations on migration of hopper bands of the red locust (Nomadacris septemfasciata Serville) in an outbreak area

Volume 22, Issue 1
  • ISSN : 0013-8789



Field observations were made on hopper bands of the Red Locust (Nomadacris septemfasciata Serville) during the wet season from January to March 1957, in the Iku outbreak area, at the northern end of the Rukwa Rift Valley in S.W. Tanganyika. Published data on hopper behaviour and migration of bands in outbreak areas are meagre. Our observations were made specially to support investigations on aerial searching for hopper bands and on hopper control by treatment of infested places with wide lattices of persistent stomach poison. Band migration was studied in order to determine the mesh-size of the insecticidal lattice (Lloyd & Yule, in press).
