摘　　要：本文主要研究了不同水稻生育期对稻粉虱 Aleurocybotus indicus种群动态的影响。研究结果表明 ,水稻分蘖期至拔节期最容易受稻粉虱为害 ,卵孵化率为 88.2 % ,拟蛹的羽化率为 82 .9% 。The paper deals with the effect of different growth stages of rice on population dynamics of Aleurocybotus indicus . The research showed that rice was damaged most severely by Aleurocybotus indicus from tilling stage to jointing stage. The incubation rate of egg of Aleurocybotus indicus was 88.2%, and the emergence rate of pupa was 82.9%, which were higher than those in other stages of rice.
