Identification of novel antimicrobial peptides from rice planthopper, Nilaparvata lugens
Insect Biochemistry and Molecular Biology, 2019In this study, two novel antibacterial peptide genes, termed lugensin A and B were identified and characterized from a rice sap-sucking hemipteran insect pest, the brown planthopper, Nilaparvata lugens. Lugensin gene expression was significantly induced by Gram-negative and Gram-positive bacterial stains under the regulation of a signal receptor, the ...

Screening and Functional Analyses of Nilaparvata lugens Salivary Proteome
Journal of Proteome Research, 2016Most phloem-feeding insects secrete gelling and watery saliva during the feeding process. However, the functions of salivary proteins are poorly understood. In this study, our purpose was to reveal the components and functions of saliva in a rice sap-sucking insect pest, Nilaparvata lugens.

Differential metabolism of neonicotinoids by brown planthopper, Nilaparvata lugens, CYP6ER1 variants
Pesticide Biochemistry and Physiology, 2020Imidacloprid is very effective in controlling Nilaparvata lugens Stål, which severely damages rice plants. Following heavy imidacloprid use, imidacloprid-resistant N. lugens, which showed cross-resistance to other neonicotinoids, appeared. We used the baculovirus/Sf9 expression system to express CYP6ER1 variants carrying A375del + A376G (del3 ...

Flight fuels in the brown planthopper Nilaparvata lugens
Journal of Insect Physiology, 1983Abstract The flight fuels of Nilaparvata are a combination of carbohydrate and lipid. In insects of constant age, lipid deposits are proportional to body weight, as is the rate of utilisation of lipid in flight. Reserves of glycogen are more variable and show no correlation with body weight. They are also always extremely low, approximately 0.2% of

[Chaotic diagnosis of Nilaparvata lugens occurrence system].
Ying yong sheng tai xue bao = The journal of applied ecology, 2004It is estimated that there are nearly 20 million hectares of rice crop being infested by Nilaparvata lugens, with an annual loss of some half a million tones of grain. In order to study the properties and laws of Nilaparvata lugens occurrence system further, the time series data of Nilaparvata lugens occurrence from 1986 to 1998 collected in Taihu Lake

การใช้ราในการควบคุมปริมาณเพลี้ยกระโดดสีน้ำตาลศัตรูข้าว Nilaparvata lugens
เชื้อราจำนวน 15 สกุล แยกได้จากเพลี้ยกระโดดสีน้ำตาลที่เป็นโรค ซึ่งรวบรวมจากศูนย์วิจัยข้าวปทุมธานี เมื่อทดสอบเชื้อราที่พบบ่อยครั้งและ/หรือเชื้อราที่มีรายงานว่าเป็นเชื้อราสาเหตุโรคของแมลง จากผลการทดลองพบว่าเชื้อรา Metarhizium flavoviride 1 สายพันธุ์ และเชื้อรา Paecilomyces fumosoroseus 1 สายพันธุ์ ทำให้อัตราการตายสะสมของแมลงสูงกว่าชุดควบคุมอย่างมีนัยสำคัญopenaire +1 more source
JNK signaling mediates wing form polymorphism in brown planthoppers (Nilaparvata lugens)
Insect Biochemistry and Molecular Biology, 2016Wing polyphenism is considered to be an adaptive trade-off between migration (long winged forms) and reproduction (short winged forms), determined by various environmental conditions. The c-Jun NH2-terminal kinase (JNK) is crucial for the regulation of the activity of a number of transcription factors, and is activated under stress and environmental ...

wStri spread dynamics in Nilaparvata lugens via discrete mathematical models
Journal of Mathematical BiologyWolbachia, an intracellular bacterium, is well-known for inducing cytoplasmic incompatibility, which has become a promising and environmentally sustainable strategy for controlling pest populations. The strain wStri, specifically identified in Nilaparvata lugens (brown planthopper), has shown potential for such biocontrol applications.
