The Potential Distribution of Rice Water Weevil (<i>Lissorhoptrus oryzophilus</i>) in China under Current and Future Climatic Conditions

Abstract

Rice water weevil (RWW), Lissorhoptrus oryzophilus, is a destructive pest of rice belonging to Coleoptera, Curculionidae, Erirhininae, and Lissorhoptrus. RWW is listed by the International Union for Conservation of Nature as one of the 100 most threatening invasive species worldwide [1,2]. In China, RWW is listed as a national agricultural plant quarantine pest. Adult RWW feed on the leaves of rice plants, leaving narrow feeding scars parallel to the venation of the leaves. The larvae feed in the roots of rice or directly bite off the rice roots [3][4][5]. The damage caused by RWW to rice reduces yield by 20%~30% [6]. It is a great threat to rice production in China.
