| 摘 要： | 进行盆栽单株罩笼接虫试验,测定褐稻虱三龄若虫在水稻分蘖末、孕穗和乳熟期,一龄若虫和成虫在孕穗期为害15天所造成的产量损失。根据褐稻虱的发育历期及其与累计取食量的关系,推算出每头褐稻虱在各虫龄期内的平均为害损失,由此推导出不同虫龄若虫和成虫的逐日为害损失率模型。探讨了一种较为准确的褐稻虱为害损失的测算方法。

| Abstract: | An inoculation experiment on the caged singly potted plants of ricewas carried out for determining the fifteen days damage of 3rd-instarnymph of brown planthopper(BPH)Nilaparvata lugens(Stal)in latetillering,booting,and milky maturity stages,and of lst-instar nymph andadult in booting stage.Based on the relationship between the develop-mental duration and the accumulated feeding amount of BPH,the meanyield loss of rice caused by BPH in each nymphal and adult stageswere calculated,and a series of day by day rice yield loss rate models indifferent BPH stages were derived.Inferences by these models wererather accurate. |
