摘要： 为明确水稻感染病毒病后对非介体稻飞虱的影响，在室内研究了水稻感染黑条矮缩病病毒后对白背飞虱的生态适应性及其体内相关的保护酶和解毒酶活性的影响。结果表明， 在感染病毒水稻植株上取食对白背飞虱若虫存活率、发育历期、成虫性比、雌成虫体质量、产卵量和卵孵化率等影响不显著，但雌成虫寿命和卵历期显著缩短。取食感病稻株的成虫体内保护酶(CAT、SOD和POD)和解毒酶(AchE、 GST和CAE)的活性均显著增强。结果证明水稻感染黑条矮缩病病毒后非介体白背飞虱的适应性提高。

Abstract: Rice black streak dwarf virus (RBSDV) transmitted by the small brown planthopper (SBPH), Laodelphax striatellus (Fallen), causes rice yield loss in east China. The whitebacked planthopper (WBPH), Sogatella fucifera (Horváth), a nonvector of RBSDV, usually shares the host rice plants with SBPH. We evaluated the effects of RBSDVinfested rice plants on the ecological fitness and   relevant defense and detoxification enzymes of WBPH in laboratory for exploring the relationship between RBSDV and the nonvector insect. The results showed that the  nymph survival rate, sex ratio, female adult weight and fecundity, and egg hatchability of WBPH fed on RBSDVinfested rice plants did not markedly differ from those on healthy plants, whereas  the adult longevity and egg duration were significantly shortened. Furthermore,   the activities of defense enzymes (CAT, SOD and POD) and detoxification enzymes (AchE，GST and CAE)  were significantly enhanced in WBPH adults fed on infected plants. Results implied that infestation by RBSDV improved  the ecological fitness of the  nonvector planthopper.
