A beetle that feeds on grain and rice and is a common pest of granaries and flour mills.
- ‘Of all the pests that feast on maize and crops like dried cassava tubers, the larger grain borer has been classified as the most dangerous.’
- ‘They are the ‘good guys’ because they don't feed on the grain but attack the larvae of the rusty grain beetle, lesser grain borer, and rice weevil.’
- ‘Either the maize is soaked by rain because of lack of storage facilities or eaten by pests such as grain borers because the storage sheds are not properly fumigated.’
- ‘Meanwhile, the southern region coordinator has called on the peasant farmers to treat their crop against the larger grain borer.’
