Tagosodes orizicolus

(Muir, 1926)

Rice Delphacid, sogata

Tagosodes orizicolus is a planthopper in the Delphacidae and a major pest of rice throughout Latin America. It is the sole of Rice Hoja Blanca virus (RHBV), a that causes significant yield losses in rice . The species also causes direct mechanical damage to rice plants through feeding and oviposition, reducing plant vigor independent of viral transmission. Its economic importance stems from this dual damage mechanism, making it a target of intensive resistance breeding programs.
