Ecology and control of rice planthoppers in Fiji
Bulletin of Entomological Research, 1963Observations 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 ...

An intelligent method for extraction of shape contour of rice planthoppers
Journal of Intelligent & Fuzzy Systems, 2016Diagnosis 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.

Ultrastructure of sensory receptors on the labium of the rice brown planthopper
Cell and Tissue Research, 1983The 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 ...

Future Planthopper Management: Increasing the Resilience of Rice Systems
2014The problem of planthoppers in rice—the causes of planthopper outbreaks and the ways of reducing the likelihood of this happening—is determined by the dynamic interaction between features of the natural system and decisions made in the human use system.

Metabolome study of rice population and resistance to brown planthopper
Journal of Integrative Plant BiologyABSTRACT 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 DiseaseThe 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 ...
