Repellent activity of ethanol extracts of 14 non-host plant species and several related mixtures were studied on rice brown planthopper(BPH) Nilaparvata lugens.The results showed that the extract of Phyllostachys pubescens leaves(40mg/mL) had the highest anti-feeding activity on BPH,an repellent rate of 47.67% at 24h after the extract application,followed by the extracts from Eichhirnia crasslpes and Piper nigrum(80mg/mL),both of which had repellent rates of 35.67% and 34.38% at 24 h,respectively.The extracts from Zanthoxylum bungeanum and Allium fistulosum had obvious repellent roles on BPH female adults.At the concentration of 80mg/ml,the repellent rates for BPH feeding and oviposition at 24h after application were all higher than 69%.A mixture of the extract from E.crasslpes(80 mg/mL) with the extract from Z.bungeanum(80 mg/mL)(a ratio of 1∶ 1) had a good repellent activity on BPH nymph and female adult feeding,and female adult oviposition,the repellent rates were 85.4%,61.2% and 83.1%,respectively.
