winter cereals

Adults and nymphs form dense colonies which appear bluish-grey and are covered with a fine, whitish powder... Nymphs are greenish and adults are a dull or greyish-green... Adults and nymphs suck on sap and high numbers can result in reduced pod set, pod fill and grain quality...

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...

Green vegetable bugs (GVB) and brown bean bugs (BBB) are equally damaging to pulse crops but green vegetable bugs (GVB) are considered a more important pest due to their abundance, widespread distribution and rate of reproduction... The damage potential of other pod sucking pests is not as great as GVB but they can cause severe damage when present in large numbers... Using the example above - if you find that the three GVB and one RBSB are 2nd instars instead of adults and the two BSB are 4th instars - an additional calculation is required to convert these instars into adult equivalents...
