A linear equation Y=69.4+1.22X was obtained in which Y indicates the collecting efficiency (%) transformed from the effective radius and X the wind speed (m/s) in a range of wind speeds of 4.9 m/s to 13.1 m/s. Aerial densities per 10 ^3m^3 of the whitebacked planthopper, Sogatella furcifera HORVATH, the brown planthopper, Nilaparvata lugens STÅL and the small brown planthopper, Laodelphax striatellus FALLEN , were estimated based on surveys conducted in 1977,1979 and 1980 on the East China Sea.}, pages = {96--98}, title = {東シナ海上で使用された捕虫網の捕虫効率}, volume = {33}, year = {1989} }
