Research Project: Rear and Release Psyllids as Biological Control Agents-An Economical and Feasible Mid-Term Solution for Huanglongbing (HLB) Disease

Location: Subtropical Insects and Horticulture Research

Project Number: 6034-22320-004-07-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Sep 1, 2012
End Date: Aug 31, 2017

To develop a psyllid population that cannot vector citrus greening that will be released to displace the current psyllids in citrus growing regions of the U.S.

Shatters: Identify molecular blockers (peptides or synthetic antibodies) that block systemic movement of the causative agent of Citrus greening, the bacterium Candidatus Liberibacter asiaticus, that are incorporated into a psyllid population that is mass reared and released to displace the existing pysllid population. Patt: Optimize Asian citrus mass rearing operations by integrating best use practices utilized at major rearing facilities. Identify most effective rearing materials and handling methodologies. Develop olfactory, visual, and auditory stimuli for attracting Asian citrus psyllid to trapping devices. Integrate innovative stimulatory and physical designs with existing trapping technology. Improve trapping technology to permit accurate estimates of the levels of genetic penetrance of 'nu-psyllids' into target release populations.
