On the biology of the brown-spotted locust, Cyrtacanthacris tatarica (L.) (Orthoptera) in the Sudan


, : On the biology of the brown-spotted locust, Cyrtacanthacris tatarica (L.) (Orthoptera) in the Sudan. Zeitschrift fur Angewandte Entomologie 81(2): 133-136

The brown-spotted locust, Cyrtacanthacris tatarica, is considered a potential pest in the Sudan. Studies in its biology showed that the average incubation period of the egg stage was 29.6 .+-. 1.2 days. The adult passed through 6-7 instars and the average duration of the 1st, 2nd, 3rd, 4th, 5th, 6th and 7th instars were 17.9, 11.6, 8.7, 10.9, 11.4, 10.6 and 11.5 days, respectively. These results differed slightly from the findings of Johnston (1932) and the information given by Ripper and George (1965).
