A monitoring-based system to enhance canegrub control best management practice for Isis sugarcane growers : final report GGP056
(BSES, 2013) Stanley, W; Chandler, K
The aim of GGP-056 was for growers to experience the effectiveness and practical value of monitoring canegrub risk as the basis for more cost-effective and efficient canegrub management: - taking the most appropriate option, including the most suitable insecticide treatment if and when and where needed, as opposed to current routines that are in the main effective but not as efficient as possible.
Barcoding a tool to assist the industry to manage insect incursions
(ASSCT, 2015) Braithwaite, K; Chandler, K; Sallam, N
THE AUSTRALIAN SUGARCANE industry has been fortunate not to have several significant insect pests that exist overseas. Moth borers are a particular concern to the Australian sugar industry due to the heavy losses they cause overseas and their potential to colonise new regions. Other high risk exotic pests include whiteflies, planthoppers and aphids. The biosecurity group in SRA is involved in many activities to prepare for possible incursions, including the development of diagnostic methods. Since the adult stage (which is required for correct taxonomic identification) may not be present in the early stage of an incursion, it is important to develop diagnostic techniques which apply to all insect stages or any available field material. The presence of frass may be the only indication that stalk damage is due to a moth borer. In such cases, identification can be greatly assisted by DNA-based techniques. For almost all animals, the universal barcode is the cytochrome oxidase I gene (COI), and this universality has led to the Barcode of Life, a project to promote DNA barcoding as a global standard for sequence-based identification. As several important exotic pests do not have publically available barcodes, SRA is assembling its own reference collection. Using the minor Australian sugarcane pest Bathytricha truncata as an experimental system, we attempted to develop methods to extract DNA and perform barcoding on frass. The method was then applied to detect three exotic borers in stalk material from PNG. Accurate detection of insect DNA from the complex stalk/frass environment is challenging, but can be achieved.
Optimum canegrub management within new sustainable cropping systems : SRDC final report BSS266
(BSES, 2010) Samson, K; Chandler, K; Sallam, N
This project addressed the issue of canegrub management in new farming systems. Many cane growers are adopting or planning to adopt one or more components of 'new farming systems' - legume rotations, reduced tillage and controlled traffic - to improve the profitability and sustainability of their farms. Canegrubs can be a constraint on cane productivity in conventional systems if not managed appropriately. Changes to farming systems could have positive or negative impacts on canegrub populations and the damage they cause, and may require changes to management tactics.
