摘要
白背飞虱在不同类型水稻品种上的分布、趋性、发育和繁殖力是不同的。它喜欢在杂交稻（汕优6号）上生活和繁殖，取食后成虫寿命最长，取食量、产卵趋性、产卵量、田间虫量均最大，种群增长快；在粳稻上却相反；常规灿稻和糯稻介于二者之间。在同一类型品种中，抗虫品种比感虫品种在上述特性方面差异明显。说明抗虫育种和种植抗虫品种是对该害虫综合治理的一项关键技术。
The experiments indicated that feeding on different varieties of ricc plant had distinct effects on the distribution preference, development and reproduction of whitebacked planthopper, Sogatella furcifera (Horvath). Feeding on the hybrid rice (Skan-you #6) resulted in the greatest number of the perch, food intake, ovipositing preference and fecundity by per female, tbe longest lifespan of the adults, the greatest number of the eggs and the pest population in the paddy fields,quicker building-up of the population. on the contrary, feeding on the round-shaped ricc resulted in the smallest number of the eggs and the pest population in tbe paddy fields, slower building-up of the population. The result of feeding on the routine long-shaped rice and the glutinous ricc was between the hybrid rice and the round-shaped rice. Feeding on the same type of rice varicties, especially resistant varieties compared with susceptible varieties, whitebacked planthopper had obvious difference on the above-mentioned characteristic. The results show that the breeding and the growing of resistant varieties are key techniques in integrated pest management.
