Interpretive Summary: Snout moth caterpillars bore into many grass crops such as corn, rice, sorghum, and sugarcane in the Western Hemisphere, causing millions of dollars of damage. This paper reviews the classification of three groups of stalkborers in Mexico, including their host plants and distribution. Keys to the species of the largest group in Mexico are provided. This information will be useful to Mexican biocontrol workers, quarantine agency identifiers, pest managers, and other scientists.
Technical Abstract: Crambine caterpillars are some of the most destructive pests of economically important grasses, such as corn, sugarcane, and rice. The classification of these stalkborers is reviewed. Characters that define higher-level taxa within the Crambinae are provided. Three genera that are pests in Mexico, Eoreuma, Chilo, Diatraea, are reviewed at the species level. Tables provide their host plants and distribution. Keys to the adults of Diatraea species occurring in Mexico are provided.
