sustainability through science & innovation
Insecticide resistance in several broadacre pests is being investigated through a research project supported by GRDC. The research is being undertaken by University of Melbourne researcher, Aston Arthur, who says the main focus of the project is to better understand insecticide resistance in mites and aphids. Resistance is becoming more prevalent in these pests. For example, resistance in redlegged earth mites to synthetic pyrethroids was first discovered in Australia just a few years ago, and in 2010 pirimicarb resistance was detected in Australian populations of green peach aphids for the first time.
By understanding the spread and frequency of insecticide resistance across southern Australia, management strategies can be devised that limit the widespread development of resistance. Assistance is being sought from anyone who experiences chemical control difficulties associated with mites or aphids this season. Growers or advisors who know of paddocks with control failures in the past are also encouraged to contact Aston.
Any information obtained from growers or advisors will be kept confidential, and assistance with recommendations for control can be provided if resistance is detected. Reports can be made directly to Dr Aston Arthur on 0427 875 040 or email alarthur@unimelb.edu.au
What is PestFacts?
PestFacts south-eastern keeps growers and advisers informed about invertebrate pests and beneficials in broadacre crops and pastures during the winter-cropping season in Victoria and southern New South Wales.
PestFacts south-eastern is run through IPMforGrains: Best Practice Insect Pest Management, a project delivered by the National Pest Information Network (cesar, DPIRD, QDAF, NSW DPI, and SARDI). This project aims to provide grain growers and advisors with information on invertebrate grain pest occurrence and equip industry with the knowledge needed to implement integrated pest management practices. This initiative is a GRDC investment and includes in-kind contributions from all project partner organisations.
We need your reports
PestFacts is produced on an ʻas-needsʼ basis and relies upon pest observations and field reports from our subscribers. If you have recently observed invertebrate pests (or beneficial species) in broadacre crops, please contact us to report your observations.
Agricultural invertebrate identification
If you are a grower or agronomist in Victoria or NSW working with broadacre crops or pastures, we can assist you with identifying invertebrates found on farms at no cost. Please contact us for identification help.
PestFacts map
PestFacts map is an interactive tool that allows users to search and view historical pest reports across Victoria and NSW. The map is updated with each issue of PestFacts to include new reports.
