NuPsyllid Presentations – Feb 2015


The purpose of Citrus Research and Development Foundation (CRDF) includes sponsoring and managing research, education and extension to develop new technologies to combat biological threats to the citrus industry and advocating their rapid deployment through education, demonstration and extension. CRDF is working in close collaboration with the California Citrus Research Board (CRB), as well as seven experts with the USDA and several universities in Florida, Texas, Arizona and California in bringing together the necessary pieces to successfully find a solution to huanglongbing (HLB) disease.

 What is CRDF

In April 2009, the National Academies of Science, at the request of the Florida Department of Citrus, formed the National Research Committee on Strategic Planning for the Florida Citrus Industry: Addressing the Citrus Greening Disease (Huanglongbing). At the same time, the forward-looking citrus industry in Florida initiated the Citrus Research and Development Foundation. When the National Research Council’s report was published in March, 2010 it included a recommendation that one organization be identified and empowered to have oversight responsibility over HLB research and development efforts. The Citrus Research and Development Foundation is a non-profit corporation organized under Florida State laws as a Direct Service Organization of the University of Florida.

 Purpose and Scope

This proposal presents research targeting the elimination of HLB as an economic threat to US citrus production by blocking the ability of the ACP to vector the bacteria CLas, the causative agent of this disease.  Our project directly and wholly addresses the RFA and the “FY 2012 Invited Coordinated Agriculture Project for Huanglongbing Disease of Citrus” request under the same Part.  Focus Area #2 includes efforts to identify and address threats from pests and diseases, including threats to specialty crop pollinators.  Sub-elements under this focus area that are targeted by this proposal include: 1. Create new scientific developments, technologies, and tools that will help reduce the incidence and impact of industry-critical insect and disease problems including, but not limited to: monitoring, control and management strategies; field based diagnostic tools; integrated management systems; and comprehensive strategies and mechanisms for eradication of newly introduced pests where eradication is a plausible strategy. 2. Develop new integrated pest management tools, such as have been demonstrated with the integrated pest management – Pest Information Platform for Extension and Education (ipmPIPE) and other area-wide, integrated systems, that possess the potential for broad impact. Proposed projects should respond to stakeholder identified critical threats.


Currently, an economically crippling plant disease (HLB), threatens all U.S. citrus production. By releasing a nuPysllid that is unable to vector the disease, we will reduce spread of HLB and begin the process of restoring the sustainability and securing the long term profitability of the citrus fruit and juice industries.  Expected outcomes include: •     Averting the loss of sustainable citrus industries in the US •     Reducing current losses to HLB in Florida (and more recently, Texas) •     Preventing HLB from expressing itself fully in other citrus producing states •     Reducing need for reliance on pesticides for reducing vector psyllid populations •     Providing novel solutions that have been developed, tested, and made ready for deployment in multiple states •     Establishing nuPsyllid rearing and monitoring systems that will have been advanced and tested •     Advancing regulatory considerations for adoption of the nuPsyllid concept •     Assessing economic potential for nuPsyllid to mitigate loss from HLB
