Citrus Psyllid Predators Show Promise The citrus psyllid (Diaphorina citri) is a significant pest in citrus agriculture, causing substantial economic losses due to its role in transmitting Candidatus Liberibacter asiaticus.
Researchers and farmers have turned their attention to biological control methods, focusing on natural predators that can regulate psyllid populations.
Spiders, wasps, and other beneficial insects feed on citrus psyllids. In some regions, the yellow garden spider (Argiope aurantia) is a primary predator of citrus psyllids.
