Abstract:
The cabbage aphid belongs to the genus Brevicoryne. The
name is derived from the Latin words “brevi” and “coryne”
and which loosely translates as “small pipes”. In aphids,
there are two small pipes called cornicles or siphunculi
(tailpipe-like appendages) at the posterior end that can be
seen if you look with a hand lens. The cornicles of the cabbage aphid are relatively shorter than those of other aphids
with the exception of the turnip aphid Lipaphis erysimi
(Kaltenbach). These short cornicles and the waxy coating
found on cabbage aphids help differentiate cabbage aphids
from other aphids that may attack the same host plant
(Carter and Sorensen 2013, Opfer and McGrath 2013).
Cabbage aphids cause significant yield losses to many crops
of the family Brassicaceae, which includes the mustards and
crucifers
