Delia
root maggot flies, seedcorn maggot flies
Delia is a genus of flies in the family Anthomyiidae, commonly known as root maggot flies. Several species are significant agricultural pests, particularly of cruciferous crops and seedlings. The genus includes economically important species such as Delia platura (seedcorn maggot) and Delia radicum (cabbage maggot), whose larvae feed on seeds, roots, and developing plant tissues. Adults are small, drab flies that feed on nectar and are often mistaken for house flies.
Evergestis
Evergestis is a genus of crambid moths established by Jacob Hübner in 1825. Species within this genus are distributed across the Palaearctic region, with some exhibiting highly disjunct, fragmented distributions. Several species are documented agricultural pests of cruciferous crops, including E. rimosalis (cross-striped cabbageworm) and E. forficalis. The genus has been subject to recent taxonomic revision, with new species described from Central Asia and Iran.
