Bird Cherry-oat Aphid
This is known to be the most common aphid found within cereal grains. In large populations it can be destructive and
is the most prominent vector of BYDV.
Bird Cherry-oat aphid body color can range from orange green
to olive green to dark olive green, and can occasionally have
a black tinge. They have long antennae and the tube-shaped
cornicles on the top rear portion of the abdomen. Usually,
there is dark brown/orange patch visible spanning the cornicles.
Management of this aphid should take place once the population reaches the economic threshold. This threshold is
between 50-60 insects per tiller. Scouting should take place in
multiple areas of the field using a zig-zag format. The Government of Saskatchewan provides a nice guide to treatment of
insect in the document listed below.
