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...

Risk factors: Coastal crops planted into cane trash blankets are at potential risk from the sugar cane armyworm... Occasional (rare) plague outbreaks of common and northern armyworms may occasionally spill over into peanuts from more favoured hosts... In-furrow sprays are registered for control at planting but trying to control cutworms in pegging crops with dense canopies is problematic due to poor coverage...

A near-perfect start with good summer and autumn rain coupled with mild temperatures saw crops jump out of the ground... Insect pests including green peach aphid (GPA) and the resulting beet western yellows virus (BWYV or synonym, turnip yellows virus) and diamondback moth (DBM) both proved headaches for growers at different stages of the growing season... Mr Baker says the colonisation of DBM in canola crops this year looks to be at a lower level for much the same reason as the risk of GPA and BWYV is this year - a much drier summer and early autumn than last year and less of a green bridge on which to survive...

A two-toned caterpillar parasite - a newly emerged adult wasp from a host pupa.. Heteropelma are often seen flying above sorghum, cotton and other summer crops... Heteropelma stings caterpillars at third instar stage and older, although third and fourth instars (8-23 mm) are preferred...
