Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2008
End Date: Sep 30, 2012

1. Determine the mechanisms and rates of geographic dispersion of the Formosan Subterranean termite (FST) in Mississippi. 2. Develop and implement biologically-based cultural/ecological control technology against termites in urban environments and incorporate into an area-wide termite IPM project in Mississippi. 3. Provide an effective educational program in Mississippi to convey information on termite biology and current effective control measures.

1. In order to best understand the spread of FST in south Mississippi, mitochondrial DNA (mtDNA) sequence markers which identify maternal lineages will be used to track termite gene flow to infer possible routes of spread of FST in Mississippi. An approach of combining different markers with alternate modes of inheritance, such as nuclear and mtDNA markers can help us discern the maternal and paternal contributions to gene flow and population structure. 2. Our laboratory results showed that repellence and virulence of certain fungal conidia when applied to tree-based mulches will significantly reduce the suitability of these mulches as a habitat for FST. The performance of mulches treated with entomopathogenic fungi against FST foraging behavior, colony mortality, and product persistence will be investigated under field conditions. 3. The general approach will include dissemination of information to the public through newsletters, pamphlets, a website, workshops, and scheduled field days. Appropriate mobile displays with current information on the biology and control of FST will be developed for use in rural communities and in public schools and at meetings of local citizen groups in Mississippi.
