Friday 29 August 2025 SARDIPestFacts
We've recorded large flights of native budworm (more than 300) at Jamestown and Port Broughton. Other sites, including Laura Bay, Jamestown, Talia, and Penong, recorded low to moderate flights (50 to 200).
Manage native budworm
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 on spraying economics.
Always apply insecticides according to label and APVMA permit instructions. Consider the impact on beneficial insects before making spray decisions.
