The aphids cause damage to cereal crops by direct feeding on sap, through transmission of plant virus such as barley yellow dwarf virus (BYDV) and cereal yellow dwarf virus (CYDV), by injecting toxins or by inducing secondary fungal growth (sooty mould) on honey dew (Thackray, et al. 2005)...

Less aphids are found flying in crops close to native vegetation.. Aphids can vector viruses that lead to yield loss in crops eg BYDV in cereals can decrease crop yields by 50%if plants are infected prior to tillering; or cause direct feeding damage which can cause yield losses of up to 10% in cereals (DAFWA 2007)... Significantly more (p<0.001) brassica aphids were found in traps that were close to native vegetation whereas traps that were far from native vegetation had significantly (p>0.001) higher numbers of legume aphids and aphids whose hosts were unknown...

Armyworm larvae are difficult to find in cereals crops as they hide at the base of plants or under clods of soil during the day... Search at the base of plants and under clods of soil to estimate the number of larvae per square metre... Monitor for larvae at dusk with a sweep net; sweep netting during the day can be unreliable...
