摘　　要：以感虫品种TaichungNative1(TN1)和RathuHeenati(RHT)为对照,以取食量、产卵痕数、产卵量和卵孵化率为测定指标,研究了白背飞虱(Sogatellafurcifera)在6个水稻品种上的取食与产卵行为的差异性。结果表明,水稻品种对白背飞虱的抗性表现出3种类型,即拒取食性为主、拒产卵性为主和拒取食性兼有拒产卵作用;水稻品种对白背飞虱拒取食和拒产卵作用间有一定相关性;水稻感、抗品种间卵的孵化率(发育率)无明显差异;在水稻抗白背飞虱产卵性的研究中,延长饲养时间是十分必要的。Tichung Native l(TN1) and Ruthu Heenati(RHT) were used as susceptible and resistant checks to study the comparative differences in feeding and ovipositing of the white-backed planthopper Sogatella fucifera (Horvath) in six resistant varieties of rice by taking feeding response, ovipositional marking, number of eggs laid and percentage of egg development as indices. The results showed that types of resistance were based on ovipositional and feeding response,anti-feeding,significant oviposition repelling and both anti-feeding and ovipositional repelling;No differences of percentage of development were found between resistant and susceptible varieties. It is concluded that it is essential to extend breeding time in resistant rice varieties.
