Taxonomic Identification of the Rice Water Weevil, Lissorhoptrus oryzophilus, at Morelos, Mexico

Research output: Contribution to journalArticle

Abstract

Adult male and female rice water weevils from fields of rice, Oryza sativa L., in the Mexican state of Morelos were collected for taxonomic identification. Based on morphological characteristics of male and female individuals, the species of rice water weevil in the State of Morelos was Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae) according to taxonomic keys. The male had a tridentate mucro in the posterior tibiae; two outward-facing bifurcated apical teeth, one moderately large apical tooth, acute, facing inward, with two distinct curved submedian setae. Females had a deeply emarginated, VII tergite with a deep indentation or notch in the middle apical part.
