Help!!!

It’s nearly citrus gall wasp season. What can I do?

Many citrus trees are affected by the native citrus gall wasp (Bruchophagus fellis) producing unsightly galls that impact the supply of nutrients to/from leaves and developing fruit. Applied entomology research was carried out at University of Adelaide (2016-18) by Dr Maryam Yazdani and John Carragher, funded by AgNova and Citrus SA, to identify the volatile compounds given off by new growth foliage that female citrus gall wasps use to locate a suitable environment to lay their eggs. That information led to a patent application and the University granting a licence to AgNova to commercialise the lure in a lure/trap product.

This seminar/workshop will:

  • Describe the research and pathway to IP protection
  • Outline commercialisation efforts
  • Discuss translation to commercial citrus orchards
  • Include a practical demonstration on controlling citrus gall wasps in the Waite Campus Orchard

Presenters:

  • Presentation: John Carragher (with slides from Dr Maryam Yazdani)
  • Orchard workshop: Ben Pike and Suzie Whiting

Special Offer:

Thanks to AgNova and Farmer John’s in Nuriootpa, limited numbers of AgNova citrus gall wasp traps will be available for purchase at 20% off RRP—just in time for the start of wasp emergence in November!
