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.

Hormone Signaling Regulates Nymphal Diapause in Laodelphax striatellus (Hemiptera: Delphacidae). [PDF]
Sci Rep, 2017 AbstractDiapause is a physiological adaptation that allows an organism to survive adverse environmental conditions. Diapause occurs at a specific developmental stage in each species. There are few reports regarding the molecular regulatory mechanism of nymphal diapause in Laodelphax striatellus, which is an important graminaceous crop pest.

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.

Cry78Aa, a novel Bacillus thuringiensis insecticidal protein with activity against Laodelphax striatellus and Nilaparvata lugens [PDF]
, 2018 Transgenic plants expressing insecticidal proteins originating from Bacillus thuringiensis (Bt) have successfully been used to control lepidopteran and coleopteran pests with chewing mouthparts. However, only a handful of Bt proteins have been identified

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.

Planting period is the main factor for controlling maize rough dwarf disease [PDF]
, 2021 Maize rough dwarf virus (MRDV) is one of the main yield-limiting factors of maize in the Mediterranean. However, knowledge about the interactions between the agroecosystem and the virus–vector–host relationship continues to be limited.
