  • AgResearch Magazine - Trap Tricks Psyllids With Sound (May 2016)
    USDA. Agricultural Research Service.
    Citrus greening is a costly disease that makes citrus fruit unmarketable. No cure exists for infected citrus trees. ARS scientists made a new trap to catch the insects that spread the disease.
  • Multi-Agency Response to Devastating Citrus Disease
    U.S. Department of Agriculture.
    USDA established a unified emergency response framework to address Huanglongbing (HLB), a serious disease of citrus that affects several U.S. states and territories. This framework will allow USDA and its many partners to better coordinate HLB resources, share information and develop operational strategies to maximize effectiveness.
