Description: In a biological control impact study, research leader Ted Center climbs up to inspect a melaleuca tree that is protected from biocontrol agents with insecticides, while entomologist Cressida Silvers checks one that was planted at the same time and inoculated with biocontrol agents. Note that the biocontrol-inoculated tree is much smaller.
