Investigation of Viruliferous Insect Rate of Planthoppers Captured by Smart Sky Net Trap (SSNT) in Korea during 2015-2017

open access: yesResearch in Plant Disease, 2018
Major viruses infecting rice are transmitted by planthoppers such as small brown planthopper (SBPH), brown planthopper (BPH) and white-backed planthopper (WBPH).

The crystal structure of Cry78Aa from Bacillus thuringiensis provides insights into its insecticidal activity

open access: yesCommunications Biology, 2022
The crystal structure of the Bacillus thuringiensis protein Cry78Aa shows it consists of a C-terminal β-pore forming domain and an N-terminal trefoil domain and suggests a mechanism underlying the function of Cry78Aa against rice planthoppers.

Tymbal Morphology and Co-ccurrence of \u3ci\u3eSpartina\u3c/i\u3e Sap-Feeding Insects (Hemiptera: Auchenorrhyncha) [PDF]

open access: yes, 2018
The exoskeletal morphology of the structures associated with the production of substrate vibrations used for communication was examined for members of three guilds of sap-feeding insects on the cordgrasses Spartina alterniflora Loisel, S.

Acoustic Signals of \u3ci\u3eGraminella Nigrifrons\u3c/i\u3e (Homoptera: Cicadellidae) [PDF]

open access: yes, 2017
The deltocephaline leafhopper, Graminella nigrifrons, produces low intensity sub- strate transmitted vibrations (signals) to facilitate location of virgin females by males during courtship.

Automated detection and identification of white-backed planthoppers in paddy fields using image processing

open access: yesJournal of Integrative Agriculture, 2017
A survey of the population densities of rice planthoppers is important for forecasting decisions and efficient control. Traditional manual surveying of rice planthoppers is time-consuming, fatiguing, and subjective. A new three-layer detection method was

The roles of small RNAs in rice-brown planthopper interactions

open access: yesFrontiers 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.

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]

open access: yes, 1998
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Effect of transgenic Bt rice on dispersal of planthoppers and leafhoppers as well as their egg parasitic wasps

open access: yes浙江大学学报. 农业与生命科学版, 2003
Effects of TT9-3 and TT9-4, which are two homozygous strains of transgenic Bt rice, on the dispersal of planthoppers and leafhoppers as well as their egg parasitic wasps were evaluated in the field.

Higher Fertilizer Inputs Increase Fitness Traits of Brown Planthopper in Rice. [PDF]

open access: yes, 2017
Rice (Oryza sativa L.) is the primary staple food source for more than half of the world's population. In many developing countries, increased use of fertilizers is a response to increase demand for rice.

Application of Integrated Pest Control Models Nilaparvata Lugens (Stal) (Homoptera: Delphacidae) In Rice Plants Outside of Sidoarjo Mud Impact Area

open access: yesAgricultural Science, 2021
This study aims to apply an integrated pest control model (IPC) of brown planthoppers (bph) on rice against the presence of natural enemies in maintaining rice productivity.
