Family Opomyzidae with pests of cereal crops (Insecta: Diptera)

The Opomyzidae are a family of insects in the order Diptera, Subordem: Brachycera, Infra-ordem: Muscomorpha. This family includes phytophagous species subservient to plants of the Poaceae family (grasses). Some species are pests of cereal crops. Its biological cycle, adapted to the phenology of grasses with an autumn-spring cycle, determines the distribution of this family, represented almost exclusively in the temperate regions of the boreal hemisphere. The purpose of this manuscript is to mention the Family Opomyzidae with pests of cereal crops. Bibliographic verification of Family Opomyzidae was carried out from 1972 to 2022. Manuscripts published in scientific journals and digital platforms on the subject were examined. Only a few species of Opomyzidae cause significant damage to agriculture: the most important are Opomyza florum (Fabricius, 1794), Opomyza germinationis (Linnaeus, 1758) and Opomyza petrei Mesnil, 1934 in the genus Opomyza, and Geomyza balachowskyi Mesnil, 1934, Geomyza combinata (Linnaeus, 1767) and Geomyza tripunctata Fallen, 1823 in the genus Geomyza.
