Abstract: The present studies were conducted in the glass house condition at IGKV Raipur during 2018 -19 with an objectiveovipositional preference of brown planthopper on rice germplasm of Chattisgarh as a source of resistance under control condition. The oviposition and unhatched eggs of female of the brown planthopper, Nilaparvatalugens(Stal.) average 75-85.25.The lowest egg laying by female BPH was in accession no. A: 145II and highest in susceptible check TN1 (126.75) and unhatched eggs range from 29.50-57.75, which was highest were resistant germplasm and lowest were TN1(10.25).The average egg laying, nymph emergence and percent unhatched eggs of this pest is described.
