Technical Abstract: Plant volatiles were identified from six species in the family Rutaceae. These species had varying degrees of susceptibility to the Asian citrus psyllid as determined by direct counts of life stages. Using a push system involving charcoal-filtered humidified air, volatiles were adsorbed on SuperQ packed in glass tubes, eluted with methylene chloride and analyzed by GC-MS using a ThermoElectron Trace GC coupled to a DSQII quadrupole MS, all controlled by Xcalibur software. The percentages are expressed as areas under the peaks relative to the entire area of the chromatogram. The identified volatiles varied among the six in both their absolute occurrence and their percentages when found in several species in common. Using these compounds or blends of these compounds in psyllid behavioral analysis can provide information useful in psyllid population management or plant breeding strategies for resistance or non-attractiveness.
