Biological Control Leads to ‘Massive Decline’ in Psyllids
Repeated evaluations throughout California showed “a massive decline – greater than 70%” in HLB-spreading Asian citrus psyllid (ACP) densities since the inception of a biological control program, a researcher reported recently. Mark Hoddle said the University of California, Riverside (UCR) and the California Department of Food and Agriculture (CDFA) turned to biocontrol because insecticide spraying wasn’t adequately controlling the psyllid. …
