The Asiatic rice borer or striped rice stemborer (Chilo suppressalis) is a moth of the Crambidae family. It is a widespread species, known from India, China, eastern Asia, Japan, Taiwan, Malaysia to the Pacific. It is a major agricultural pest in rice production.
The wingspan is 25 mm. Females are somewhat larger than the males. Adults have pale yellow forewings, each with one or more dark spots. The hindwings are white.
The larvae feed on Chaetochloa verticellata, Echinochloa crusgalli cruspavonis, Echinochloa stagnina, Eleusine indica, Panicum barbinode, Paspalum conjugatum and rice. They bore the stems of their host plants, and therefore are classified as rice stem borers. The larvae are yellow, with five, dim, longitudinal lines, and can grow to a length of about 25 mm. As a serious pest of rice they are largely responsible for the great reduction in the rice growing acreage in Hawaii.
Pupation takes place in a stem of the food plant.
