Abstract

                                The levels of mechanism of resistance such as antixenosis (host preference) and antibiosis against brown planthopper, Nilaparvata lugens Stal was studied in certain resistant accessions under laboratory. conditions. The levels of resistance were found to be varying in different resistance parameters in the tested accessions. However comparatively less honey dew excretion, low food ingestion and assimilation, decreased nymphal survival, increased nymphal duration, high growth index and reduction life span were recorded in all resistant accessions than the susceptible TN1.

Key words : Rice, Nilaparvata lugens, Resistance mechanism, Antixenosis, Antibiosis, Resistance accessions
