Agro-ecological zoning of brown planthopper [Nilaparvata lugens (Stal)] incidence on rice (Oryza sativa L.)
Multiple linear regression models (pest-weather models) were developed between monthly mean brown planthopper (BPH), Nilaparvata lugens light trap catches and monthly mean values of minimum temperature (Tmin), maximum temperature (Tmax), morning relative humidity (RH 1 ) and evening relative humidity (RH 2 ) observed at Maruteru, Andhra Pradesh during 2000-2007 kharif seasons. Comparison betwee...
متن کاملIdentification of Qtls for Brown Planthopper (nilaparvata Lugens Stal.) Resistance in Ril Mapping Population of Rice (oryza Sativa L.)
The brown planthopper (Nilaparvata lugens Stal.) is one of the major insect pests of rice (Oryza sativa L.). Exploitation of Host Plant Resistance is a major component to manage this pest. The development of rice varieties that are resistant to the brown planthopper is an important objective in current breeding programmes. This study was undertaken to identify QTLs for BPH resistance from an el...
متن کاملTranscriptome Analysis of the Brown Planthopper Nilaparvata lugens
BACKGROUND The brown planthopper (BPH) Nilaparvata lugens (Stål) is one of the most serious insect pests of rice in Asia. However, little is known about the mechanisms responsible for the development, wing dimorphism and sex difference in this species. Genomic information for BPH is currently unavailable, and, therefore, transcriptome and expression profiling data for this species are needed as...
متن کاملA reovirus in the brown planthopper, Nilaparvata lugens.
A new virus, belonging to the reovirus group, was found in an apparently healthy colony of the brown planthopper, Nilaparvata lugens, and was referred to as the Nilaparvata lugens reovirus (NLRV). The virus was found in the cytoplasm of the insect cells, sometimes associated with tubular structures, which is one of the characteristic features in tissues infected with reoviruses. The virus was p...
متن کاملThe Transcription Factor OsWRKY45 Negatively Modulates the Resistance of Rice to the Brown Planthopper Nilaparvata lugens
WRKY transcription factors play a central role not only in plant growth and development but also in plant stress responses. However, the role of WRKY transcription factors in herbivore-induced plant defenses and their underlying mechanisms, especially in rice, remains largely unclear. Here, we cloned a rice WRKY gene OsWRKY45, whose expression was induced by mechanical wounding, by infestation ...
