Brachycorynella asparagi

Definition

A species of aphid in the family Aphididae (order Hemiptera), originally described by Mordvilko in 1929. This species is associated with asparagus (Asparagus spp.) as its host plant, reflecting the specific epithet. Like other aphids, it is a phloem-feeding sternorrhynchan with a piercing-sucking mouthpart stylet complex and typically exhibits complex life cycles involving parthenogenetic and sexual generations.

Etymology

Generic name Brachycorynella from Greek brachys (short) + coryne (club) + diminutive -ella, likely referring to short, club-shaped structures; specific epithet asparagi from Latin asparagus, the host plant genus.

Example

Brachycorynella asparagi colonies on asparagus ferns can cause stunting and distortion of spears; monitoring for this specialist aphid is important in commercial asparagus production, where it may be confused with the more widespread asparagus aphid, Aphis fabae solanella.

Usage Notes

Distinguished from the common asparagus aphid (Aphis fabae solanella or related Aphis species) by morphological features of the cornicles and cauda; specialist aphids like this species often show narrow host range restricted to a single plant genus or family. The 1929 description by Mordvilko places this species in a genus whose taxonomic limits have been revised in modern aphid systematics.
