褐飞虱的再迁飞能力
Re-emigration Capacity of the Brown Planthopper, Nilaparvata lugens
摘要
Abstract
Re-emigration potential of the brown planthopper (BPH),Nilaparvata lugens after an emigration and feeding different resistant varieties was simulated. Tethered flight of brown planthopper on a set of computerized flight mill revealed that the natural population of BPH in the rice cropping areas of the lower reaches of Yangtze River consisted of individuals with different flight characteristics, i.e., deposited type (flying less than 20 min), migratory type (flying more than 20 min, MT), strong migratory type (flying more than 160 min, SMT) and re-emigration type (2nd flying more than 20 min, RET). The flight capability and the differentiation of the MT of BPH was influenced significantly by the nutritive conditions. The individuals feeding on the sensitive varieties at heading stage would show a lower ratio of MT, but a stronger ability of migration and re-emigration among their MT individuals. The RET rate would be increased markedly by keeping apart the females, and the SMT individuals would display higher performance of re-emigration. There would only be 0.84 and 4.9 percent of the RET BPH among the natural populations and MT individuals respectively.关键词
