Abstract:The green rice leafhopper, Nephotettix bipunctatus cincticeps (Uhler), a serious pest of rice in Korea, occasionally causes direct damage resulting in total crop failures and also transmits rice dwarf disease or virus stunt in rice paddies. During 1959 the life history of the leafhopper was studied on potted rice plants, out of doors. Based upon 4 successive rearings, the period from egg to adult averaged 47 days at Suwon, Korea. Light traps used in paddy fields from 1952 to 1961 indicated 3 large peaks each year. The highest numbers of leafhoppers were recovered between August and September and the peak of the population oceurred in 1957.
Of 7 insecticides, Bayer 29493 (O,O-dimethyl-O-[4-(methylthio)-m-tolyl] phosphorothiate); Sevin® (1-naphthyl N-methylcarbamate); DDT; malathion; Plant Protection Ltd. PP 175 (O,O-dimethyl S-(4,6-diamino-1,3,5-triazin-2-yl) phosphorothiolothionate methyl); and diazinon, involving 12 formulations and several combinations, tested for initial and residual mortality on potted rice plants against this leafhopper, Sevin was most effective. High mortality (96 to 100%) occurred at 1 to 10 days after application of the insecticide at 0.05% concentration and 28 gal. of spray per 1,000 square meters.
