The rice leaf-folder Cnaphalocrocis medinalis GUENEE is a serious pest in western Japan. We measured the net photosynthetic rate and dark respiration rate of undamaged, folded and damaged leaves using a portable system. The undamaged leaf net photosynthetic rate was 21.98 μmol・m^<-2>・s^<-1> at the leaf top and 21.81 μmol・m^<-2>・s^<-1>at the leaf base. The folded leaf net photosynthetic rate was 10.04-14.23 μmol・m^<-2>・s^<-1> or 42%-66% that of healthy leaves. The damaged leaf net photosynthetic rate of was -1.12 μmol・m^<-2>・s^<-1>. The dark respiration rates of undamaged and damaged leaves were 0.45 μmol・m^<-2>・s^<-1> and 2.05 μmol・m^<-2>・s^<-1>, respectively. The relationship between damaged leaf area (X) and net photosynthetic rate (Y) is Y=25.8-0.27X (γ^2=0.97,ρ<0.01). The relationship between damaged leaf area (X) and dark respiration rate (Y) is Y=0.36+0.019X (γ^2=0.68,ρ<0.01).
