Rice Stripe Virus Modulates the Feeding Preference of Small Brown Planthopper from the Stems to Leaves of Rice Plants to Promote Virus Infection.

Phytopathology, 2022
Research on plant-virus-vector interactions has revealed that viruses can enhance their spread to new host plants by attracting non-viruliferous vectors to infected plants or driving viruliferous vectors to non-infected plants.

A rice plant expressing viral glycoprotein NSvc2-NS reduces the transmission of rice stripe virus by the small brown planthopper.

Pest Management Science, 2022
BACKGROUND Plant viruses transmitted by arthropod vectors threaten crop health worldwide. Rice stripe virus (RSV) is one of the most important rice viruses in East Asia and is transmitted by the small brown planthopper (SBPH).

Bacterial microbiota in small brown planthopper populations with different rice viruses

Journal of Basic Microbiology, 2017
The 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.

MicroRNA-315-5p promotes rice black-streaked dwarf virus infection by targeting a melatonin receptor in the small brown planthopper.

Pest Management Science, 2021
BACKGROUND MicroRNAs (miRNAs), a class of small non-coding endogenous RNAs, play key roles in various biological processes. Most plant viruses are transmitted by insect vectors.

Small brown planthopper resistance loci in wild rice (Oryza officinalis)

Molecular Genetics and Genomics, 2014
Host-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, 2002
Abstract 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.

Bio-effects of near-zero magnetic fields on the growth, development and reproduction of small brown planthopper, Laodelphax striatellus and brown planthopper, Nilaparvata lugens

Journal of Insect Physiology, 2014
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.

Host-Plant Induced Shifts in Microbial Community Structure in Small Brown Planthopper, Laodelphax striatellus (Homoptera: Delphacidae)

Journal of Economic Entomology, 2021
Microbiome associated with insects play vital roles in host ecology and physiology. The small brown planthopper (SBPH), Laodelphax striatellus, is a polyphagous insect pest that caused enormous damage to a wide range of cereal crops.

Lethal and sublethal effects of sulfoxaflor on the small brown planthopper Laodelphax striatellus

Journal of Asia-Pacific Entomology, 2016
Abstract Laodelphax striatellus (Fallen), as an important pest of gramineous crops, has developed resistance to multiple classes of insecticides, impairing control efficiency. However, the application of insecticides is still the main control measure for it.

Biochemical Characterization of Carboxylesterase in the Small Brown Planthopper Laodelphax striatellus (Fallén)

Pesticide Biochemistry and Physiology, 1994
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 ...
