A Cripavirus in the brown planthopper, Nilaparvata lugens

open access: yesJournal of General Virology, 2016
A Cripavirus-like long unique sequence was identified during transcriptome sequencing of the brown planthopper (BPH), Nilaparvata lugens. This unique sequence demonstrated high similarity with the whole-genome sequence of cricket paralysis virus, including 5' and 3' untranslated regions; thus we considered it the whole genome of a new virus. We propose

Dynamical modeling of the control of brown planthoppers by Beauveria bassiana and Cyrtorhinus lividipennis

open access: yesAdvances in Difference Equations, 2019
In this work, the control of brown planthopper, a major pest of rice, when a biological control agent (Cyrtorhinus lividipennis) and a pathogen (Beauveria bassiana) are utilized is investigated mathematically.

Planthopper-Secreted Salivary Calmodulin Acts as an Effector for Defense Responses in Rice

open access: yesFrontiers in Plant Science, 2022
The brown planthopper (Nilaparvata lugens, BPH) and small brown planthopper (Laodelphax striatellus, SBPH) are major pests of rice (Oryza sativa) in Asia. These piercing-sucking insects secrete saliva into the host during feeding.

Vitellogenin and Vitellogenin-Like Genes in the Brown Planthopper [PDF]

open access: yesFrontiers in Physiology, 2019
Vitellogenin (Vg) is precursor of vitellin. Here, we identified a Vg (NlVg) and two Vg-likes (NlVg-like1 and NlVg-like2) in the brown planthopper, Nilaparvata lugens. Phylogenetic analyses showed that NlVg-like1 and NlVg-like2 are not clustered with the conventional insect Vgs associated with vitellogenesis.
