Asia Regional Project on Fall Armyworm and Brown Planthopper

This new initiative is supported by South Korea's Asian Food and Agriculture Cooperation Initiative (AFACI) in partnership with the CSIRO Genomics Team and the ASEAN FAW Action Plan. This project will focus on three major components to better understand these two serious regional pests.

This page is designed to update the project team and wider regional stakeholders on the work of the initiative as well as opportunities to provide feedback and participate in events.

Component 1: will build genomic evidence-based information to infer FAW (Year 1) and BPH populations (Year 2) connectivity across the region as the first step for the development of pest management solutions

This will build on the successful work by CSIRO's Dr. Wee Tek Tay and a team of experts under a previous GRDC, ACIAR, and CRDC co-funded project that aimed to understand better FAW population connectivities, management options, and resistance profiles in Australia, Southeast Asia, Oceania, and East Africa (Cambodia, Lao PDR, Malaysia, Myanmar, Indonesia, Philippine, Vietnam, Papua New Guinea, New Zealand, Uganda).

Component 2: will look at building skills across the region on bioassay work to understand resistance profiles in the two species through the development of standardized protocols between the project partner countries, as well as providing hands-on training to analyze and quality control DNA sequence datasets for molecular diagnostic purposes. Identifying potential biocontrol solutions for future management of FAW and BPH will be a key focus of the work

Component 3: will look at applying solutions in the field with a focus on practical and effective IPM solutions for farmers that promote sound monitoring and management of FAW and BPH populations, to reduce conventional chemical pesticide use by 30%.

Project Timeline

Project dates: October 2023-to-October 2026

The 3-year project is structured into three distinct phases and will include workshops, annual meetings, webinars, demonstration field trials, and regularly scheduled virtual meetings taking place every two months. 

Goals include:

First year :

Second year :

  • A better understanding of FAW population structure across the 10 AFACI partner countries

  • Exploration of genomic approaches to addressing pest threats.  

  • An understanding of the molecular diagnostic approach, an ability to process DNA barcoding-related sequences, and an ability to perform molecular diagnosis  


  • A better understanding of implementing protection strategies to improve crop health and farmer communication strategies.  

  • Better understanding of BPH population diversity across the partner countries  

  • An understanding of the molecular diagnostic approach, an ability to process DNA barcoding-related sequences, and an ability to perform molecular diagnosis  

Third year :

  • Increasing confidence in interpreting genomic signatures concerning invasion biology

  • An appreciation of biological control agents' genetic diversity available to manage FAW and BPH  

  • Increasing knowledge and confidence in best practices for farmer communication  


  • A better understanding of target pests FAW and BPH population structure to support the development of ecologically sound and sustainable management strategies.  

  • An appreciation for the importance of research collaboration to address transboundary plant pests, diseases, and biosecurity threats

  • Development of IPM strategies that can lead to a reduction of conventional chemical pesticides.

There will be a chance to join some of the webinars offered in this project. We will provide an update on these on this page.


  • First Workshop: 4-6 December 2023 in Hanoi, Vietnam

  • Second Workshop:  TBC August 2024 in Lao PDR

  • Third Workshop: TBC

  • Fourth Workshop: TBC

First Workshop

2023 Kick-Off Workshop PMP+ Asia Region FAW and BPH Diagnostics and Monitoring and Surveillance Program
Hanoi, 4-6th December 2023

Researchers from across South Asia -Southeast Asia (Bangladesh, Bhutan, Cambodia, Indonesia, Lao PDR, Nepal, Philippines, Thailand, Sri Lanka, South Korea, and Vietnam), Australia, and South Korea met in Hanoi for 3 days from 4-6 December 2023 to kick off the new 3-year Asia Diagnostics, Monitoring, and Surveillance Program on Fall Armyworm (FAW) and Brown Planthopper (BPH).
