The study aimed to investigate the vectorial capacity of twelve insect species to transmit Rice Yellow Mottle Virus (RYMV) from diseased seedlings of a susceptible rice variety (Bouaké 189) and a perennial wild rice (Oryza longistaminata) to seven alternative host plants. Results indicated that Trichispa sericea, Chaetocnema pulla, Chnootriba similis, Conocephalus longipennis, Oxya hyla, Paratettix sp., Zonocerus variegatus, Euscyrtus sp., Cofana spectra, Cofana unimaculata, Locris rubra and Locris maculata were capable of transmitting RYMV from infected Bouaké 189 and Oryza longistaminata to alternative weed hosts Leersia hexandra, Imperata cylindrica, Digitaria horizontalis, Echinochloa colona, Echinocloa crus-pavonis, Eleusine indica and Brachiaria lata. Only Chaetocnema pulla, Trichispa sericea, Chnootriba similis, Oxya hyla, Zonocerus variegatus, Euscyrtus sp., Parattetix sp., Cofana spectra, Cofana unimaculata and Locris rubra played an important role in transmitting the disease from rice to O. longistaminata, Leersia hexandra and Imperata cylindrica. The present study confirmed the vectorial capacity of these vectors out of which eight were reported for the first time in West Africa.
