摘要: 对寄主经历不同的稻褐飞虱Nilaparvata lugens 3龄若虫致害特性的研究结果表明:在抗虫品种Mudgo上的生活经历显著提高试虫在含Bphl基因的Mudeo、IR26、IR28、IR34上的蜜露排泄量、存活率及试虫对Mudgo的选择性:而ASD7上的经历仅显著提高试虫在ASD7上的蜜露量和存活率。不同品种上的经历对试虫的影响有所不同。同时,各经历试虫 在抗虫品种上的蜜露排泄量显著小于在TNl上的排泄量。

Abstract: The infestation of 3rd instar Nilaparvata lugens with different experiences was studied, and the following results were obtained. The experiences on resistant variety "Mudgo" could improve the honeydew excretion and survival of N. lugens on theBphl-carried varieties such as Mudgo, IR26, IR28, IR34, and also enhance the preferencefor the tested variety "Mudgo'; the experience of N. Lugens on resistant variety "ASD7", however, only contributed to the increase of honeydew excretion and survivalon the same variety, thus implying that the effects of experience were characterized by variety-dependence to some extent. It is still recognized that the amount of honeydew excretion was much less on Mudgo and ASD7 than on TN1 for N. lugens with the same experience on the resistant varieties.

Key words: Nilaparvata lugens, resistance to insect, host-related experience, infestation, rice variety
