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 distribution, tropism, development and fecundity of WBPH in different types of rice varieties are different. It likes to live and breed on hybrid rice (Shanyou 6). The longest life span, feeding amount, ovipositional tendency, fecundity and fieldworm population of the hybrid rice (Shanyou 6) On the contrary; conventional rice and glutinous rice between the two. In the same type of varieties, insect-resistant varieties than susceptible varieties significantly different in the above characteristics. This shows that insect-resistant breeding and planting of insect-resistant varieties are one of the key technologies for the comprehensive management of this pest.
