| 摘 要： | 不同抗性水稻品种对褐稻虱生物学特性有明显的影响.试验结果证实:(1)褐稻虱若虫在感性品种上的存活率、发育速度高于抗性品种.(2)褐稻虱成虫在感性品种上的卵巢发育程度、产卵量以及卵孵化率均高于抗性品种.(3)在感性品种上取食的褐稻虱,其分泌的蜜露量较抗性品种的多.(4)抗性品种对褐稻虱的种群增长有明显的抑制作用.本文还对抗性品种在褐稻虱综合防治中的应用问题进行了讨论.

| Abstract: | The distinct effects of the rice varieties with different resistance on the bionomics of brown planthopper Nilaparvata lugens(St(?)l)(BPH)were observed.The main results obtained were as follows:(1) The survival rate and the development rate of BPH nymphae on the susceptible varieties were greater than that on the resistant varieties.(2)The extent of ovarical development and the fecundity of BPH adults,and hatchability of BPH eggs on the susceptible varieties were greater than that on the resistant varieties.(3)The area of honeydew secreted by BPH feeding on susceptible varieties was greater than that on the resistant vari- eties.(4)The population growth of BPH feeding on the resistant varieties was restrainted.In the paper,the application of resistant varieties in integrated control of BPH was also discussed. |
