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 کاملBuprofezin susceptibility survey, resistance selection and preliminary determination of the resistance mechanism in Nilaparvata lugens (Homoptera: Delphacidae).
BACKGROUND Buprofezin has been used for many years to control Nilaparvata lugens (Stål). Assessment of susceptibility change in the insect is essential for maintaining control efficiency and resistance management. RESULTS Eleven-year surveys showed that most field populations were susceptible before 2004. However, substantially higher levels of resistance (up to 28-fold) were found in most of...
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 کاملDriving Pest Insect Populations: Agricultural Chemicals Lead to an Adaptive Syndrome in Nilaparvata Lugens Stål (Hemiptera: Delphacidae)
The brown planthopper (BPH) is a devastating pest of rice throughout Asia. In this paper we document the BPH biogeographic range expansion in China over the 20-year period, 1992 to 2012. We posed the hypothesis that the range expansion is due to a syndrome of adaptations to the continuous presence of agricultural chemicals (insecticides and a fungicide) over the last 40 years. With respect to b...
متن کاملSelectivity of lynx proteins on insect nicotinic acetylcholine receptors in the brown planthopper, Nilaparvata lugens.
Neuronal nicotinic acetylcholine receptors (nAChRs) are major excitatory neurotransmitter receptors in both vertebrates and invertebrates. Two lynx proteins (Nl-lynx1 and Nl-lynx2) have been identified in the brown planthopper, Nilaparvata lugens, which act as modulators on insect nAChRs. In the present study, two lynx proteins were found to act on the triplet receptor Nlalpha1/Nlalpha2/beta2 e...
