End Date: Jun 3, 2013
1. To conduct host specificity tests with the beetle Lilioceris egena for possible use as a biological control agent against the invasive Asian vine Dioscorea bulbifera (air potato). 2. To assess impacts of the beetle Lilioceris cheni on populations of air potato in Florida.
1. Challenge adult and larval L. egena with potential food resources, including roots, tubers, corms, taproots, bulbs, and rhizomes from a variety of plant species in the Dioscoreaceae and closely related families as food sources. 2. Measure L. cheni impacts on the following parameters: (a) abundance and biomass of existing subterranean tubers of air potato; (b) aerial biomass production, including vine growth and propagule (bulbil) production of air potato; and (c) recovery and maintenance of native plant diversity.
