Changes in reflectance of rice seedlings during planthopper feeding as detected by digital camera: Potential applications for high-throughput phenotyping.

PLoS ONE, 2020
Damage to grasses and cereals by phloem-feeding herbivores is manifest as nutrient and chlorophyll loss, desiccation, and a gradual decline in host vigour. Chlorophyll loss in particular leads to a succession of colour changes before eventual host death.

Virulence and SSR Diversity of Brown Planthopper (Nilaparvata lugens) Adapted on Differential Rice Host Varieties

Hayati Journal of Biosciences, 2021
Brown planthopper biotype 1, 2, 3 and a representative field population are required for resistance screening of promising rice lines in Indonesia, but the current biotype stocks has shown deviation in virulence patterns.

Migration dynamics of an important rice pest: The brown planthopper (Nilaparvata lugens) across Asia—Insights from population genomics

bioRxiv, 2020
Brown planthoppers (Nilaparvata lugens) are the most serious insect pests of rice, one of the world’s most important staple crops. They reproduce year-round in the tropical parts of their distribution, but cannot overwinter in the temperate areas where ...

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.

An R2R3 MYB transcription factor confers brown planthopper resistance by regulating the phenylalanine ammonia-lyase pathway in rice

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Brown planthopper (BPH) is the most destructive pest of rice and causes losses of billions of dollars annually. Genetic improvement of BPH resistance in rice remains a major challenge because of the limited number of resistance genes that ...

The population of brown plant hopper in paddy fields at Kedah / Aida Zabri [PDF]

, 2017
Brown planthopper (BPH) (Nilaparvata lugens) is one of the major insect pests that affect rice production in Kedah. The BPH attack caused the paddy field to have hopperburn phenomena which is the result of dried up of leaves.
