Technical Abstract: The Asian citrus psyllid, which is a worldwide pest that spreads citrus greening disease, may best be controlled by finding varieties of citrus that are resistant to the psyllid. We tested trifoliate citrus and trifoliate hybrids for resistance to the psyllid. Trifoliates were nearly all resistant, and some hybrids also were resistant. We are currently working to identify chemical volatiles produced by the plants that may influence host plant selection by the psyllid, and so far we have found differences in volatiles between resistant and susceptible plants.
