The vector Nephotettix nigropictus reproduced on O. eichengeri, O. glaberrima, O. malampuzhaensis, O. minuta, O. nivara, O. officinalis, O. perennis, O. punctata, O. sativa, Echinochloa colonum, Ischaemum indicum, Leersia hexandra, and Paspalum orbiculare; N. virescens reproduced only on O. glaberrima, O. nivara, O. perennis, O. sativa, E. colonum, and P. orbiculare.
