Insecticide application and its effect on the density of rice planthoppers, Nilaparvata lugens and Sogatella furcifera, in paddy fields in the Red River Delta, Vietnam. [PDF]
J Pestic Sci, 2019 The brown planthopper, Nilaparvata lugens, and the white-backed planthopper, Sogatella furcifera, are significant pest insects for rice. Both species are able to survive year-round in northern Vietnam's Red River Delta, which includes a large rice ...

Automated Counting of Rice Planthoppers in Paddy Fields Based on Image Processing
Journal of Integrative Agriculture, 2014 A quantitative survey of rice planthoppers in paddy fields is important to assess the population density and make forecasting decisions. Manual rice planthopper survey methods in paddy fields are time-consuming, fatiguing and tedious.

Development and evaluation of an automated classification and counting system for rice planthoppers captured on survey boards [PDF]
Scientific ReportsRice planthoppers are the most economically important insect pests of rice in Asia. Traditional surveys to examine their abundance and composition in paddy fields involve human visual inspection, which requires considerable time and effort by expert ...

Protocol for propagating and inoculating rice grassy stunt virus in rice plants using brown planthoppers [PDF]
STAR ProtocolsSummary: Rice grassy stunt virus (RGSV) causes a severe viral disease in rice and is transmitted by brown planthoppers (BPHs) (Nilaparvata lugens Stål). Here, we present a protocol for propagating RGSV and establishing controlled infection in rice plants.

Insecticidal effect of aconitine on the rice brown planthoppers.
PLoS ONE, 2019 The brown planthopper, Nilaparvata lugens (Stål), severely damages rice production and develops high level resistance to several classes of insecticides. To find potential insecticidal resources is always important.

The roles of small RNAs in rice-brown planthopper interactions
Frontiers in Plant Science, 2023 Interactions between rice plants (Oryza sativa L.) and brown planthoppers (Nilaparvata lugens Stål, BPHs) are used as a model system to study the molecular mechanisms underlying plant-insect interactions.
