Intervention effect All predators except Amblyseius swirskii significantly reduced Asian citrus psyllid egg numbers on citrus shoots.
Intervention effect Lacewings suppressed Asian citrus psyllid eggs by 94% in the laboratory.
Intervention effect Mealybug destroyers suppressed Asian citrus psyllid eggs by 76% in the laboratory.
Intervention effect Minute pirate bugs suppressed Asian citrus psyllid eggs by 68% in the laboratory.
Intervention effect Lacewings reduced Asian citrus psyllid egg suppression by 97% in whole-plant cages.
Intervention effect Orius insidiosus reduced egg density by 73% in whole-plant cages.
Observation Cryptolaemus montrouzieri and Chrysoperla rufilabris each consumed more than 100 eggs per exposure period.
Observation Orius insidiosus consumed on average 65 eggs.
Recommendation Targeting ACP eggs with lacewings or mealybug destroyers may substantially enhance sustainable psyllid management in citrus.
