Genetic evidence of transoceanic migration of the small brown planthopper between China and Japan
Pest Management Science, 2022AbstractBACKGROUNDThe small brown planthopper, Laodelphax striatellus (Fallén), is an important pest of rice. It is suspected of migrating over the sea from China to Japan. However, where in China it comes from and how it affects Japanese populations remain unclear.RESULTSHere, we studied the genetic structure of 15 L.

Life history responses of the small brown planthopper Laodelphax striatellus to temperature change
Journal of Thermal Biology, 2023Temperature is a key environmental factor in ectotherms and influences many life history traits. In the present study, the nymphal development time, sex ratio and wing dimorphism of the small brown planthopper Laodelphax striatellus were examined under the conditions of constant temperatures, naturally varying temperatures (or different generations ...

Bacterial microbiota in small brown planthopper populations with different rice viruses
Journal of Basic Microbiology, 2017The small brown planthopper (SBPH) is an important virus vector, transmitting Rice stripe virus (RSV), and Rice black-streaked dwarf virus (RBSDV). Insect symbionts play an essential role in the insect fitness, however, it is still unclear about their contributions to viral transmission by SBPH.

Small brown planthopper resistance loci in wild rice (Oryza officinalis)
Molecular Genetics and Genomics, 2014Host-plant resistance is the most practical and economical approach to control the rice planthoppers. However, up to date, few rice germplasm accessions that are resistant to the all three kinds of planthoppers (1) brown planthopper (BPH; Nilaparvata lugens Stål), (2) the small brown planthopper (SBPH; Laodelphax striatellus Fallen), and (3) the ...

Transgenic rice lines with enhanced resistance to the small brown planthopper
Crop Protection, 2002Abstract Transgenic rice lines containing the snowdrop ( Galanthus nivalis ) lectin gene (GNA) were investigated for the stability of expression of the GNA gene in the sixth (R6) generation. Western blot analysis revealed that GNA was stably expressed among the R6 individual plants at comparable levels with those from their parental lines.

Magnetic fields markedly affect the growth and development of many species of organisms potentially due to cryptochrome and endogenous presence of magnetic materials. Sensitivity to magnetic fields can also be involved in geomagnetic orientation by some long-distance migratory insects.

Male Killing Caused by a Spiroplasma Symbiont in the Small Brown Planthopper, Laodelphax striatellus
Journal of Heredity, 2013Spiroplasma-mediated late male killing was found in the small brown planthopper, Laodelphax striatellus. Female-biased colonies (maternal lines, N = 4) were established from planthoppers collected in Taiwan and Japan. This sex ratio distortion was maternally inherited (sex ratio of total number of progenies [female:male]: 488:0 in F1, 198:7 in F2, 407 ...

Organ-specific transcriptome response of the small brown planthopper toward rice stripe virus
Insect Biochemistry and Molecular Biology, 2016Rice stripe virus (RSV) causes rice stripe disease and is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH) in a persistent, circulative, and propagative manner. The alimentary canal and salivary gland of SBPH play important roles in viral replication and transmission.

Argonaute (AGO) proteins are essential catalytic components of the RNA‐induced silencing complex and play central roles in RNA interference. Using a combination of bioinformatics and rapid amplification of cDNA ends (RACE) methods, putative AGO subfamily members, ls‐AGO1 and ls‐AGO2, were cloned and characterized from the small brown planthopper ...

Abstract Several forms of carboxylesterase were observed in a malathion-resistant small brown planthopper, Laodelphax striatellus Fallen, by isoelectrofocusing. To study the mechanisms of increased esterase activity, esterases were purified and their biochemical characteristics were investigated in five active esterase isozymes of two resistant ...
