| Abstract: | The niche breadth, the niche overlap, the percentage similarity and the interspecific competition coefficient of three species of rice planthoppers (Laodelphax striatellus, Sogatella furcifera and Nilaparvata lugens) were estimated by means of investigating their spatial niche and trophic niche. The competitive relation of three rice planthoppers in trophic necessary and their position and function in the paddy fields were also revealed according to the population occurrence and fluctuation of them. |
