The effect of flooding stress on food consumption of different adult female brown planthoppers （Nilaparvata lugens） biotypes adult female fed on resistant rice varieties were studied by measuring their honeydrew. The results indicated that the effectsincidence of flooding stress on the food consumption of different brown planthopper different biotypes fed on resistant rice varieties were different. The impact of flooding stress on the food consumption of brown planthopper biotype Ⅱ fed on ASD7 was the greatest, and followed by it′s great the impact on food consumption of brown planthopper biotype Ⅱ fed on IR36,IR42 and brown planthopper biotype bangladesh fed on IR56,RNR3070,OM997-6 and ARC5833. The low-impact on food consumption of brown planthopper biotype Ⅱ fed on OM997-6 and the two brown planthopper biotypes fed on RP1976-18-6-4-2 and ARC5984 was slim.The food consumption of brown planthopper biotype Ⅱ fed on Guiyin 901 and two brown planthopper biotypes fed on RHT, Ptb33 and 570011 were not impacted influenced by the flooding stress.
