Transmission of Rice Stripe Virus by Laodelphax striatellus (Fallén)

Japanese Journal of Phytopathology, 1973
Movement of the stripe virus in rice leaf was intercepted or delayed by pre-treatments known to affect the function of phloem, viz., with chemicals such as sodium azide, monoiodoacetic acid, dinitrophenol, chloroform and alcohol, cooling or steam-heating at the portion about 2cm below the area to be fed by viruliferous smaller brown planthoppers ...

Genome sequence of the small brown planthopper, Laodelphax striatellus. [PDF]

Gigascience, 2017
Abstract Background Laodelphax striatellus Fallén (Hemiptera: Delphacidae) is one of the most destructive rice pests. L. striatellus is different from 2 other rice planthoppers with a released genome sequence, Sogatella furcifera and Nilaparvata lugens, in many biological characteristics, such as host

Take-off time of the first generation of the overwintering small brown planthopper, Laodelphax striatellus in the temperate zone in East Asia. [PDF]

PLoS ONE, 2015
Overseas migration of the small brown planthopper, Laodelphax striatellus (Fallén), occurs during the winter wheat harvest season in East Asia. Knowing the take-off time of emigrating L.

Study about photoinduction-based technology for trapping small brown planthopper

Frontiers in Plant Science, 2022
To provide a theory to guide the selection of the illumination parameters of light emitting diode (LED)-based light sources used for trapping Laodelphax striatellus, we used LED light sources and devices built in-house to detect L.

Resistance irrelevant CYP417A2v2 was found degrading insecticide in Laodelphax striatellus. [PDF]

Ecol Evol, 2017
AbstractCytochrome P450 monooxygenases (CYPs) usually overexpressed in resistant strain were found involved in oxidative detoxification of insecticides. In this study, an investigation was conducted to confirm if resistance irrelevant CYPs which were not overexpressed in resistant strain before, were capable of degrading insecticides.

RNAi silencing of rice black-streaked dwarf virus P10 and two insect vector genes to reduce virus transmission protects rice plants against RBSDV

Journal of Plant Interactions, 2021
Rice black-streaked dwarf virus (RBSDV) is a virus transmitted by Laodelphax striatellus (L. striatellus), which poses a serious threat to rice production. P10, a major outer capsid protein of RBSDV, which plays a key role in viral infection.

Background‐dependentWolbachia‐mediated insecticide resistance inLaodelphax striatellus [PDF]

Environmental Microbiology, 2020
SummaryAlthough facultative endosymbionts are now known to protect insect hosts against pathogens and parasitoids, the effects of endosymbionts on insecticide resistance are still unclear. Here we show thatWolbachiaare associated with increased resistance to the commonly used insecticide, buprofezin, in the small brown planthopper (Laodelphax ...

Survival of overwintering nymphs of the small brown planthopper and its contribution to emergence timing

Ecosphere, 2023
This study developed a model for predicting the emergence timing of the first generation of the small brown planthopper, Laodelphax striatellus, by clarifying the effects of low temperature on survival and development of overwintering nymphs.

Detection of Rice stripe virus in Laodelphax striatellus by direct dot immunobinding assay

浙江大学学报. 农业与生命科学版, 2005
Three horseradish peroxidase-linked monoclonal antibodies of Rice stripe virus (RSV), HRP-3B9, HRP-2H2 and HRP-2E5, were produced by NaIO4 method. The diluted times of the three enzyme-linked antibodies were 1∶25600, 1∶1600 and 1∶3200, respectively.

Insect tissue-specific vitellogenin facilitates transmission of plant virus. [PDF]

PLoS Pathogens, 2018
Insect vitellogenin (Vg) has been considered to be synthesized in the fat body. Here, we found that abundant Vg protein is synthesized in Laodelphax striatellus hemocytes as well. We also determined that only the hemocyte-produced Vg binds to Rice stripe
