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 کاملEvaluation of Antimicrobial Activity of Different Solvent Extracts of Medicinal Plant: Melia Azedarach L
Antimicrobial efficiency of Melia azedarach L. a medicinal plants (leaf extracts) were examined using Methanol, Ethanol, Petroleum ether and water, as solvents and tested against eight human pathogens like Bacteria: Bacillus cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Fungi: Aspergillus niger, Aspergillus flavus, Fusarium oxisporum, Rhizopus stolonifer using agar we...
متن کاملHypoglycaemic and antihyperglycaemic activity of Ageratum conyzoides L. in rats.
The hypoglycaemic and antihyperglycaemic properties of the aqueous extracts of the leaves of Ageratum conyzoides L. were evaluated in normoglycemic and in streptozotocin-induced diabetic rats, in order to validate its use in folk medicine. Tested animals were given the aqueous extracts of the plant at the doses of 100, 200 and 300mg/kg. These doses were tested also on glucose loaded normal male...
متن کاملProteome Analysis of Rice (Oryza sativa L.) Mutants Reveals Differentially Induced Proteins during Brown Planthopper (Nilaparvata lugens) Infestation
Although rice resistance plays an important role in controlling the brown planthopper (BPH), Nilaparvata lugens, not all varieties have the same level of protection against BPH infestation. Understanding the molecular interactions in rice defense response is an important tool to help to reveal unexplained processes that underlie rice resistance to BPH. A proteomics approach was used to explore ...
