Abstract
Rice tungro disease (RTD) is one of the important rice pests and obstacles in increasing rice production in Indonesia causing crop failure. It is caused by a combined infection between rice tungro bacilliform virus (RTBV) and rice tungro spherical virus (RTSV) and is transmitted by several species of green leafhopper (GLH). This research aims to assess the severity level of RTD, identify the GLH species, and detect the tungro disease virus molecularly in Central Sulawesi, Indonesia. The survey was conducted at the rice production center at five regencies in Central Sulawesi situated at different altitudes namely, Tolitoli, Donggala, Parigi Moutong, Sigi, and Poso district. The GLH was collected using sweep nets for species identification morphologically while the rice samples showed RTD symptoms were taken for detection of the tungro viruses molecularly. The results showed that RTD attacks the rice at five regencies observed and its severity was quite high ranging from 20 % to 90 %. There were four species of GLH recorded belonging to Nephotettix Matsumura genus, that is: N. virescens, N. nigropictus, N. parvus, and N. malayanus. They were distributed differently at the study sites. N. parvus and N. malayanus were first recorded on Sulawesi Island. DNA amplification by polymerase chain reaction (PCR) showed all rice plants collected from five districts in Central Sulawesi were infected by RTBV.
