Cabbage aphids living on the edge.. "Field trials at York and New Norcia in 2013 showed that cabbage aphids - which can cause feeding damage to canola crops in late winter and spring - tend to be distributed along crop edges," Mr Severtson said... Mr Severtson said that as well as highlighting the importance of weed control, the results implied that a border spray might be just as effective at controlling cabbage aphids as a full paddock spray, saving growers time and money...

Research shows cabbage aphids living on the edge.. "The new research clearly suggests that infestation of racemes occurs later in the growing season, and that in the weeks prior, the same canola plants host cabbage aphids feeding on leaves in the bottom of the canopy," Mr Severtson said... Mr Severtson said that in some years, cabbage aphids and other species such as turnip aphids could cause widespread damage in late winter and spring by feeding on growing canola shoot tips, causing wilting, flower abortion and reduced pod set...

Cabbage aphids prefer to colonise the underside of lower leaves on canola plants, rather than the racemes (flowering spikes)... Growers and advisors are encouraged to report incidences of crop pests and diseases, including cabbage aphids, via email to DAFWA's PestFax service at: pestfax@agric.wa.gov.au..

The objective of the project is to develop a training and research resource in applied entomology that can serve the future needs of the Australian grains industry nation-wide... In Australia, as in other countries, there has been a decline in education and training courses in applied entomology such that the supply of trained researchers and field entomologist world-wide has decreased markedly... Plot and glasshouse trials for spider mites in maize and redlegged earth mites and aphids in canola indicate that insect pests prefer host plants affected by an imbalance of certain nutrients...

Time to tame the green bridge and keep insect pests at bay.. "If aphids are found in very low numbers on only a few plants in the crop, we advise treatment should not be immediately undertaken, but instead further regular monitoring conducted to assess whether the aphid numbers increase to a level that warrants spraying... Mr Kimber said a range of beneficials including ladybird beetles, hoverflies and Braconid wasps that parasitise aphids have been observed during March in close proximity to volunteer canola heavily infested with cabbage aphids...
