Revolutionising management of fruit and banana spotting bugs through genome empowerment (BY23003)

This project is building new, science‑based options to manage fruit spotting bug and banana spotting bug, two native pests that cause major yield and quality losses in crops such as avocado, macadamia and other tree crops. Current control relies heavily on broad‑spectrum insecticides, which can be costly, hard to time and disruptive to beneficial insects. The project focuses on developing more targeted and sustainable alternatives.

The research works by sequencing and analysing the genomes of fruit spotting bug and banana spotting bug for the first time. This genetic information is used to understand how the insects feed, damage crops and detect pheromones. The project then identifies and tests specific genes that could be targeted using RNA interference (RNAi), a highly targeted pest control approach. Laboratory bioassays are used to validate these targets and assess practical, non‑transgenic delivery methods. Population genetics is also included to ensure potential tools work across different growing regions.

The expected outcome is a strong foundation for future, grower‑focused pest management tools. These include improved pheromone‑based monitoring options and the early development of precise, crop‑safe RNAi control strategies. Tangible outputs include publicly available annotated genome resources, scientific publications and an industry‑ready final report to support future adoption and on‑farm impact.
