Native budworm moth trapping update: First to mid-September
Monday 15 September 2025 PestFacts
We recorded large flights of native budworm (more than 300) at Jamestown. Other sites, including Penong, Port Broughton, Cummins, Laura Bay, Talia, Kimba, Rudall, and Frances, recorded moderate to low flights (20-250).
Check the latest native budworm moth activity through MothTrapVis (Cesar Australia).
Caterpillar numbers largely determine potential crop damage. The native budworm spraying threshold provides a more precise measure of potential loss. For example, 1 caterpillar per 10 sweeps equates to 20,000 caterpillars per hectare in pulse crops (DPIRD).
Refer to DPIRD's native budworm spraying threshold factsheet for more details on spraying economics.
Always apply insecticides according to label and APVMA permit instructions. Consider the impact on beneficial insects before making spray decisions.
