【Objective】To study spatial distribution patterns and sampling techniques for the larvae of rice water weevil,Lissorhoptrus oryzophilus,under seedling throwing transplanting and conventional seedling transplanting in Guangxi,and to provide a theoretical basis for insect survey and integrated control of rice water weevil. 【Method】The spatial distribution patterns of rice water weevil larvae were investigated by aggregation indices,Taylor's power principle and Iwao's regression methods. Different sampling tec...
