A rapid multiplex PCR assay for species identification of Asian rice planthoppers (Hemiptera: Delphacidae) and its application to early-instar nymphs in paddy fields.

open access: yesPLoS ONE, 2021
Rice (Oryza sativa L.) is the main cereal crop in many Asian countries. The Asian rice planthoppers, Nilaparvata lugens (Stål) (brown planthopper), Sogatella furcifera (Horváth) (white-backed planthopper), and Laodelphax striatellus (Fallén) (small brown

Rice Sesquiterpene Plays Important Roles in Antixenosis against Brown Planthopper in Rice [PDF]

open access: yesPlants, 2021
The rice sesquiterpene synthase II gene (OsSTPS2, LOC_Os04g27430), which is involved in the antixenosis defense mechanism of rice against brown planthopper (BPH) infestation, was identified in the BPH-resistant rice variety Rathu Heenati (RH). In contrast, the gene was not functional in the BPH-susceptible rice variety KDML105 (KD).

Deep CNN-Based Planthopper Classification Using a High-Density Image Dataset

open access: yesAgriculture, 2023
Rice serves as the primary food source for nearly half of the global population, with Asia accounting for approximately 90% of rice production worldwide. However, rice farming faces significant losses due to pest attacks. To prevent pest infestations, it

Resistance of Some Rice Varieties (Oryzae sativa Linnaeus) to the Brown Planthopper (Nilaparvata lugens Stal) using the Honey Dew Test

open access: yesJurnal Proteksi Tanaman, 2023
The brown planthopper (Nilaparvata lugens Stal) is the main pest of rice plants around the world, because it can cause crop failure or crop loss. One technique to control brown planthopper is to use resistant varieties.

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.

Oxalic Acid Inhibits Feeding Behavior of the Brown Planthopper via Binding to Gustatory Receptor Gr23a

open access: yesCells, 2023
Plants produce diverse secondary compounds as natural protection against microbial and insect attack. Most of these compounds, including bitters and acids, are sensed by insect gustatory receptors (Grs).

Insulin receptors and wing dimorphism in rice planthoppers [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2017
Wing polymorphism contributes significantly to the success of a wide variety of insects. However, its underlying molecular mechanism is less well understood. The migratory planthopper (BPH),Nilaparvata lugens, is one of the most extensively studied insects for wing polymorphism, due to its natural features of short- and long-winged morphs.
