Keeping our agents in control
Researchers are investigating the use of cochineal insects to control prickly pear, and plume moths to control horehound. It takes time to identify and select the natural enemies that will do most damage, and rigorous studies are conducted to determine whether control insects could have any impact on non-target species. Developing techniques for incorporating biological control into integrated weed management strategies is necessary to maximise the effectiveness of biocontrol agents.
