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(Horvath),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.
