dc.description.abstractMultiple 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 (RH1) and evening relative humidity (RH2) observed at Maruteru, Andhra Pradesh during 2000-2007kharif seasons. Comparison between predicted and observed BPH light trap catches at Nellore (kharif 2004 and 2005), Ragolu(kharif 2003-2007) and Rajendranagar (kharif 2005 and 2007) evinced very high level of congruence between them, therebyvalidating agro-ecological zoning of BPH incidence in Andhra Pradesh. Knowledge of BPH incidence levels in different zoneswould facilitate strategic decisions with regard to selection of crop cultivars and management practices, and prediction of probablelife of resistant cultivars.en_US
