Rice stripe disease caused by virus (RSV) is one of the most devastating plant viruses rice and causes enormous losses in production. RSV transmitted from to small brown planthopper ( Laodelphax striatellus) a circulative–propagative manner. The recent reemergence this pathogen East Asia since 2000 has made studied over past two decades. Extensive studies have resulted substantial advances rega...

Barnyard grass (var. onyzicela) showed no apparent damage in paddy fields where hopperburn occurred by a large number of NL lugens. The causes of barnyard grass resistance to this inscct and thc insect-host interrelations of threc species of planthoppers (N. Iugens, L. striatellus and S. farctfera) between rice plant and barnyard grass were studicd. Nymphs of IV. Iugens could not grow by feedin...

Understanding dispersal ability in pest species is critical for both theoretical aspects of evolutionary and population biology and from a practical standpoint, such as implementing effective forecasting systems. The small brown planthopper (SBPH), Laodelphax striatellus (Fallén), is an economically important pest, but few data exist on its dispersal ability. Here, we used mitochondrial and nuc...

In this study, we evaluated the adaptability of the small brown planthopper (SBPH), Laodelphax striatellus (Hemiptera: Delphacidae) to four rice cultivars including Shengdao13 (SD13), Shengdao14 (SD14), Shengdao15 (SD15), and Zixiangnuo (ZXN) using the age-stage, two-sex life table with a simplified method for recording egg production (i.e., every five days vs. daily). The intrinsic rate of inc...

Rice stripe virus (RSV), the type member of the genus Tenuivirus, transmits by the feeding behavior of small brown planthopper (SBPH), Laodelphax striatellus. To investigate the interactions between the virus and vector insect, total RNA was extracted from RSV-viruliferous SBPH (RVLS) and non-viruliferous SBPH (NVLS) adults to construct expressed sequence tag databases for comparative transcrip...

A cell line from the small brown planthopper (SBPH; Laodelphax striatellus) was established to study replication of rice stripe virus (RSV), a tenuivirus. The SBPH cell line, which had been subcultured through 30 passages, formed monolayers of epithelial-like cells. Inoculation of cultured vector cells with RSV resulted in a persistent infection. During viral infection in the SBPH cell line, th...
