1) Re-invasion study: More than twenty colonies of FST in Armstrong Park, which is located adjacent to the New Orleans French Quarter, have been eliminated. The re-invasion scenario will be monitored with a series of in-ground monitors placed on the perimeter of the park and throughout the foraging territory of the previously eliminated colonies. Alate sticky card traps will be use to monitor the density of the general population of new invaders. 2) Area-wide management: Poplarville, MS, and the Stennis Space Center have been identified for the sustainable FST management program. The relatively isolated rural town and an isolated area at the Center are infested with FST, and serve as ideal sites for the project. A preliminary survey indicated multiple populations of FST in the town that can be readily characterized, monitored, and baited. Detected FST populations, thus far include the police department, old railroad station, and a few other residential areas. They will be monitored to determine the density and extent of the infestation with survey stakes in bucket stations and alate sticky traps in key areas of the town to survey the overall FST populations. Commercial bait products or a prototype of the "hermetically sealed bait" will be installed at sites with FST ground activity. Baits will be applied by ARS personnel. If there is a need to involve pest control firms for bait applications, a single firm will be selected for applying baits in a well-defined area. If the anticipated area is too large for a single pest control firm to handle, then a contiguous block of a reasonable size will be assigned to one firm. Bait consumption will be monitored using a modified version of a colony elimination system. Following the bait installation, local activity of FST will be monitored and documented with bucket stations. The overall FST activities in the town will be monitored annually by using the sticky trap survey of alates in the spring.
