The Formosan subterranean termite, Coptotermes formosanus, is a serious pest in several parts of the world and is the most destructive insect in Louisiana. The density of the Formosan subterranean termite in the French Quarter, New Orleans, Louisiana, USA is very high. A large area pilot test for area wide management of this insect was begun in 1998 in the French Quarter to reduce densities of termites and demonstrate the effectiveness of the approach of treating all properties in a large area using area wide management. The pilot test is a cooperative effort between the LSU Agricultural Center, USDA-Agricultural Research Service and New Orleans Mosquito and Termite Control Board. All but four of 323 properties in a contiguous 15 block area in the French Quarter were treated using commercially available baits or non repellent termiticides selected by property owners and applied by professional pest control operators. Properties were inspected for conducive conditions and proper treatment after treatments were made. Data on termite activity were collected using glue boards for alates and in ground monitors for foraging activity. Alates were sampled two to three times weekly during the flight season (May through July 15) in both 1998 and 1999 using glue boards hung near lamps on street lights. Monthly monitoring of foraging activity began in January, 1999 to determine the number of stations with termites and amount of wood consumed. Reductions in densities of alates between years were not found; probably as a result of the limited time treatments had been in place. The percentage of in ground monitoring stations with termites was lower in the treated zone than outside the treated zone after September 1999. Continued treatment and monitoring are required to determine the extent of and the long term effects of the area wide management program.
