摘要： Rice black-streaked dwarf virus (RBSDV), an important rice virus, is transmitted by vector small brown planthopper (SBPH) in a persistent manner, but not transovarial transmission. In order to obtain viruliferous SBPH nymphs for relevant research, a simple and reliable method was developed, through allowing SBPH adults laying eggs on RBSDV-infected rice plants. The results showed the hatching nymphs on diseased plants could early acquire virus, and the virus was detected in 2nd-instar nymphs from the spawning method, which was earlier than insect feed on diseased plant. The average viruliferous rate of SBPH from the spawning method was 32.9%, which was not lower than the feeding diseased plant method. The novel method was very easy to operate and time-saving, facilitating the study on the interaction between RBSDV and SBPH nymphs (especially young 2nd 4th instar nymphs), such as, the effect of RBSDV on nymph development, host plant orientation preference of viruliferous nymph, identification of viral interacting protein in nymph, etc.
