Validation of Reference Genes for Quantitative Real-Time PCR in Laodelphax striatellus

Journal of Integrative Agriculture, 2014
The normalization of quantitative real-time PCR (qPCR) is important to obtain accurate gene expression data, and the most common method for qPCR normalization is to use reference genes. However, reference genes can be regulated under different conditions.

The loss of the urea cycle and ornithine metabolism in different insect orders: An omics approach

Insect Molecular Biology, Volume 34, Issue 5, Page 632-644, October 2025.
Among urea cycle enzymes, only the nitric oxide synthase gene is universally present across insect genomes. All Hemiptera species lack the enzymes needed to convert citrulline to arginine, and some also lack the pathway from arginine to ornithine. Putrescine and spermidine synthesis is conserved in all insects, but aphids lack the capability to produce

Determination of population changes of Laodelphax striatellus (Fallen, 1826) and Sogatella vibix (Haupt, 1927) (Hemiptera: Delphacidae) by using different sampling methods in second crop maize in Diyarbakir province

, 2010
The aim of present study was to investigate population changes of Laodelphax striatellus (Fallen, 1826) and Sogatella vibix (Haupt, 1927) Delphacidae (Hemiptera) by using yellow sticky traps and D-Vac in second crop maize fields of Diyarbakir province in

Wolbachia-induced apoptosis associated with increased fecundity in Laodelphax striatellus (Hemiptera: Delphacidae) [PDF]

, 2018
Wolbachia influence the fitness of their invertebrate hosts. They have effects on reproductive incompatibility and egg production. Although the former are well characterized, the mechanistic basis of the latter is unclear.

Diapause Induction and Termination in the Small Brown Planthopper, Laodelphax striatellus (Hemiptera: Delphacidae)

PLoS ONE, 2014
The small brown planthopper, Laodelphax striatellus (Fallén) enters the photoperiodic induction of diapause as 3rd or 4th instar nymphs. The photoperiodic response curves in this planthopper showed a typical long-day response type with a critical daylength of approximately 11 h at 25 °C, 12 h at 22 and 20 °C and 12.5 h at 18 °C, and diapause induction ...

Rice Black-streaked Dwarf Virus Preparation and Infection on Rice

Bio-Protocol, 2017
Rice black-streaked dwarf virus (RBSDV), a member of genus Fijivirus in the family Reoviridae, infects rice, maize, barley and wheat, and can seriously affect crop yields. RBSDV is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH)

Insect-transmitted plant virus balances its vertical transmission through regulating Rab1-mediated receptor localization

Cell Reports
Summary: Rice stripe virus (RSV) establishes infection in the ovaries of its vector insect, Laodelphax striatellus. We demonstrate that RSV infection delays ovarian maturation by inhibiting membrane localization of the vitellogenin receptor (VgR ...

Data from: Influences of two coexisting endosymbionts, CI-inducing Wolbachia and male-killing Spiroplasma, on the performance of their host Laodelphax striatellus (Hemiptera: Delphacidae)

, 2019
The small brown planthopper Laodelphax striatellus (Hemiptera: Delphacidae) is reported to have the endosymbiont Wolbachia, which shows a strong cytoplasmic incompatibility (CI) between infected males and uninfected females. In the 2000s, female-biased L.

Knockdown of timeless Disrupts the Circadian Behavioral Rhythms in Laodelphax striatellus (Hemiptera: Delphacidae)

Environmental Entomology, 2018
Most living organisms developed the innate clock system to anticipate daily environmental changes and to enhance their chances of survival. timeless (tim) is a canonical clock gene. It has been extensively studied in Drosophila melanogaster (Diptera: Drosophilidae) as a key component of the endogenous circadian clock, but its role is largely unknown in
