Preference Assessment of White-backed Planthopper Feeding on Rice

Journal of Visualized Experiments, 2020
Exploiting insect-resistant rice germplasm resources and related genes is the primary need for breeding insect-resistant varieties, but the accuracy of the identification of insect-resistant phenotypes of rice is a major difficulty. It is urgent to develop a new method or improve existing methods to screen rice for insect resistance.

Biosystematics of rice brown planthopper and rice green leafhoppers

Proceedings: Animal Sciences, 1987
The Brown planthopper,Nilaparvata lugens (Stal) is causing serious damage to rice cultivation in tropical countries of Asia for the last 10–15 years. Green leafhoppers,Nephotettix spp. are also assuming serious proportions in different parts. This has been attributed to improved rice production technology, especially with the introduction of high ...

Mechanisms of Rice Planthopper Resistance to Insecticides

2014
History of insecticidal control of rice planthoppers in Asia and associated resistance development is summarized. Rice planthoppers have developed resistance against all the insecticides that were commonly used. Experiences of past 30 years of chemical control of the rice planthoppers in many parts of Asia confirm that the use of any kind of ...

Prediction of rice brown planthoppers based on system dynamics

2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015
Rice brown planthoppers are the main pest of Chinese rice production, and belong to the long distance migratory pest. The descriptive model of a rice brown planthopper has complex features, which are dynamic, continuous, nonlinear, multi-variable, multi-feedback, and so on.

Ultrastructure of sensory receptors on the labium of the rice brown planthopper

Cell and Tissue Research, 1983
The ultrastructure of the sensory receptors located on the labium of the rice brown planthopper is described; possible functions of individual receptors are suggested on morphological grounds. Uniporous chemosensilla which may or may not possess a mechanoreceptive dendrite, domed multiporous chemosensilla, and mechanoreceptive pegs are present on the ...

An intelligent method for extraction of shape contour of rice planthoppers

Journal of Intelligent & Fuzzy Systems, 2016
Diagnosis of rice planthopper pests based on imaging technology is an efficient means to develop intelligent agriculture. Effective contour automation extraction is an important pretreatment technology at the early stage for identifying and classifying rice planthoppers.

Ecology and control of rice planthoppers in Fiji

Bulletin of Entomological Research, 1963
Observations were made in Fiji on the ecology and control of two Delphacid planthoppers on rice, Sogatella furcifera (Horv.) and Nilaparvata lugens (Stål), the latter species having apparently been responsible for a devastating outbreak in 1959. The studies covered three rice seasons, 1961, 1962, and 1963, most of the research being done at Koronivia ...

Metabolome study of rice population and resistance to brown planthopper

Journal of Integrative Plant Biology
ABSTRACT Herbivorous insects pose a major threat to crop production, with rice suffering significant yield losses due to infestation by the brown planthopper (BPH). To understand the genetic and metabolic basis of BPH resistance in rice, we conducted metabolomic analysis and performed metabolite‐based genome‐wide ...

Resistance to Planthoppers and Southern Rice Black-Streaked Dwarf Virus in Rice Germplasms

Plant Disease
The damage caused by the white-back planthopper (WBPH, Sogatella furcifera) and brown planthopper (BPH, Nilaparvata lugens), as well as southern rice black-streaked dwarf virus (SRBSDV), considerably decreases the grain yield of rice. Identification of rice germplasms with sufficient resistance to planthoppers and SRBSDV is essential to the breeding ...
