Comparative rate of development of Orosius albicinctus Distant (Cicadellidae: Homoptera) on different host plants

Abstract

SUMMARYThe comparative rate of development of Orosius albicinctus Distant was studied on different host plants, sesame, sannhemp, radish, purslane, lucerne, chicory, Indian rape, sugar beet and black gram. The duration of the egg stage was the shortest (7·1 days) on sesame and was prolonged to 12·0 days on chicory. The nymphal duration was again minimal (11·9 days) on sesame and was prolonged to 15·4 days on chicory. The nymphal survival was also more on sesame than on the other hosts. Thus, among all the host plants tested sesame was found to be the best suited host for this leaf-hopper.
