Hayhurstia
Hayhurstia is a monotypic genus of aphids in the family Aphididae, containing the single species H. atriplicis. The genus is notable for its role in biological control research, as populations serve as reservoirs for parasitoids that have been used in pest management programs. It is associated with Chenopodium (goosefoot) plants in agricultural and urban environments.

Chenopodium aphid, Saltbush Leaf-Fold Aphid
Hayhurstia atriplicis is a holocyclic, monoecious aphid species associated with Chenopodium host plants. It is considered economically indifferent but serves as a perennial reservoir for parasitoid species, particularly Diaretiella rapae and Ephedrus nacheri. These parasitoids have been utilized in biological control programs targeting other pest aphids, including Diuraphis noxia and Schizaphis graminum.
