    "abstract": "The Asian citrus psyllid (ACP),\n Diaphorina citri\n Kuwayama, has spread to citrus growing regions nearly worldwide and transmits phloem-limited bacteria (\nCandidatus\n Liberibacter spp.) that are putatively responsible for citrus greening disease.  Host plant resistance may hold promise as a control tactic for ACP, but ACP has a broad host range and resistance in \nCitrus \nand relatives to ACP has only recently been actively explored.  Very low abundances of ACP were found on two accessions of \nPoncirus trifoliata \nL. in a field survey (Westbrook et al., 2011).  Therefore, we tested whether 81 accessions of \nP. trifoliata \nand x\nCitroncirus \nsp.\n \n(hybrids of \nP. trifoliata \nand \nCitrus \nspp.) from the USDA-ARS National Clonal Germplasm Repository for Citrus and Dates were resistant to ACP by determining whether these accessions influence oviposition and lifespan of adults in no-choice tests.  There was a higher abundance of eggs on the control (\nCitrus macrophylla\n Wester)\n \nthan nearly all accessions of \nP. trifoliata\n, and zero eggs were laid on 36% of the accessions.  Additionally, more eggs were laid on the control than 10 of 34 accessions of x\nCitroncirus\n.  Lifespan of adults was ~2.5-5 times longer on 11 of the 17 trifoliates and trifoliate hybrids we tested.  \nP. trifoliata \nappears to have both antixenosis and antibiosis resistance to ACP.  We have initiated research to identify the specific traits conferring resistance.  To identify chemical mechanisms that may promote resistance, we collected volatiles from several pairs of closely related susceptible/resistant accessions of trifoliates and trifoliate hybrids and found differences in the volatile profiles.",
