灰飞虱（Laodelphaxstriatellus）是水稻条纹病毒（ricestripevirus，RSV）的重要传播媒介。本研究采用电穿透图技术研究了L.与病毒传播有关的纹状体。本文研究了抗病品种盐稻8号对灰飞虱取食行为和传毒效率的影响。检查纹状体。结果表明，除了韧皮部汁液摄入阶段，这是以前报道的行为与病毒的收购，唾液分泌和口针运动的阶段是相关的RSV收购幼稚L。纹状体。naïve L的非渗透期持续时间。与感病对照相比，烟稻8号上的黑条蚜取食时间显著缩短，取食时间显著延长。未感染L.烟稻8号上的黑条病率仅为感病对照的28%。通过产毒L.在唾液分泌、口针运动和韧皮部汁液摄取阶段可发生纹状体。烟稻8号显著延长了含毒L.的非侵入期，显著缩短了其取食树液的时间。纹状体。带毒L.健康烟稻8号对黑腹小蜂的摄食率显著低于对照，降低了27%。本文还探讨了品种对褐飞虱取食行为和病毒传播的影响机制。对纹状体进行了讨论。品种对病毒传播的影响对病毒病的防治具有重要意义。
Laodelphax striatellus is an important vector of rice stripe virus (RSV). In this study, electrical penetration graph technology was applied to investigate the feeding behavior of L. striatellus associated with virus transmission. The effects of a disease-resistant variety Yandao No. 8 on the feeding behavior and subsequent virus transmission efficiency of L. striatellus were examined. The results indicate that in addition to the phloem sap ingestion phase, which was previously reported as a behavior associated with virus acquisition, phases of salivation and stylet movement were relevant to RSV acquisition by naïve L. striatellus. The duration of the non-penetration phase of naïve L. striatellus on healthy Yandao No. 8 plants was significantly longer, and the duration of sap ingestion was significantly shorter compared to those on a susceptible control. RSV acquisition rate of naïve L. striatellus on Yandao No. 8 was only 28 % of that on the susceptible control. Virus inoculation by viruliferous L. striatellus could occur during the salivation, stylet movement, and phloem sap ingestion phases. Yandao No. 8 significantly prolonged the duration of the non-penetration phase and significantly shortened the duration of sap ingestion in viruliferous L. striatellus. Virus inoculation rate of viruliferous L. striatellus feeding on healthy Yandao No. 8 was significantly lower, decreasing by 27 %, than that of the control. The mechanisms of varietal effects on the feeding behavior and virus transmission of L. striatellus are discussed. The varietal effect on virus transmission should have significance for viral disease control.
