1. To screen citrus species and related species in the USA and China for resistance to the Asian citrus psyllid. 2. To identify plant traits which impart resistance to the psyllid, traits that could be used to develop commercial citrus varieties with psyllid resistance for the purpose of reducing incidence of huanglongbing disease.
Subject candidate citrus species and related species in free-choice infestation studies and determine species that are avoided by the psyllid for food and reproduction. Evaluate these apparently resistant plant species in no-choice studies to confirm they are avoided by the psyllid. Plant resistant species in the field and monitor them over time to determine if they develop huanglongbing.
