Ongoing Research

  • Ecological and physiological drivers for Asian citrus psyllid movement.
  • Host selection and preference of Asian citrus psyllid between plants infected with Candidatus Liberibacter asiaticus or uninfected plants, identifying the visual and chemical cues associated with host choice.
  • The effect of enhanced nutritional programs for citrus on psyllid populations in the field and host selection with respect to infection status of plants with Candidatus Liberibacter asiaticus in the field and laboratory.
  • Overwintering strategies of the Asian citrus psyllid.
  • The role of methyl salicylate and other host volatiles in host location by the Asian citrus psyllid and its parasitoid Tamarixia radiate.
