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

Migration of rice planthoppers and their vectored re-emerging and novel rice viruses in East Asia

Frontiers in Microbiology, 2013
This review examines recent studies of the migration of three rice planthoppers, Laodelphax striatellus, Sogatella furcifera, and Nilaparvata lugens, in East Asia. Laodelphax striatellus has recently broken out in Jiangsu province, eastern China.

RNA interference depletion of the Halloween gene disembodied implies its potential application for management of planthopper Sogatella furcifera and Laodelphax striatellus. [PDF]

PLoS ONE, 2014
Sogatella furcifera and Laodelphax striatellus are economically important rice pests in China by acting as vectors of several rice viruses, sucking the phloem sap and blocking the phloem vessels.

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 ...

First mitogenome for the tribe Saccharosydnini (Hemiptera: Delphacidae: Delphacinae) and the phylogeny of three predominant rice planthoppers

European Journal of Entomology, 2018
The mitochondrial genome of Saccharosydne procerus (Matsumura) is the first sequenced in the tribe Saccharosydnini (Hemiptera: Delphacidae: Delphacinae).

Identification and characterization of a TLR13 gene homologue from Laodelphax striatellus involved in the immune response induced by rice stripe virus

Journal of Integrative Agriculture, 2020
Toll-like receptors (TLRs) are the critical superfamily homologues that initiate sensing of the invasion of pathogens by the Toll pathway. As one of several intracellular nucleic acid-sensing TLRs, TLR13 is activated by an unmethylated motif present in ...

Identification and profiling of conserved and novel microRNAs in Laodelphax striatellus in response to rice black-streaked dwarf virus (RBSDV) infection

Genomics Data, 2015
MicroRNAs (miRNAs) are small non-coding endogenous RNA molecules that play important roles in various biological processes. This study examined microRNA profiles of Laodelphax striatellus using the small RNA libraries derived from virus free (VF) and ...

High Diversity and Functional Complementation of Alimentary Canal Microbiota Ensure Small Brown Planthopper to Adapt Different Biogeographic Environments

Frontiers in Microbiology, 2020
Almost all insects harbor commensal bacteria in the alimentary canal lumen or within cells and often play a pivotal role in their host’s development, evolution, and environmental adaptation.
