Research Project: Using Modified Insect Neuropeptides to Control the Asian Citrus Psyllid

Location: Insect Control and Cotton Disease Research

Project Number: 3091-22000-038-066-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Jul 1, 2019
End Date: Jun 30, 2021

Objective:
Design and synthesize biostable, mimetic versions of insect neuropeptide hormones native to the Asian citrus psyllid for evaluation by collaborating groups as environmentally friendly pest control agents in laboratory, greenhouse and field experiments. The Asian citrus psyllid transmits a pathogen that causes 'citrus greening', or Huangbinglong, disease, a major problem for citrus growers in the U.S. New tools for controlling the psyllid are urgently needed, as insecticide resistance among psyllid populations is now prevalent throughout Florida.

Approach:
Biostable neuropeptide hormone mimics will be developed, synthesized and purified in quantities sufficient to conduct pest control trials against Asian citrus psyllid under laboratory, greenhouse and field conditions; as well as to determine specific mode of action for EPA registration purposes.
