Levee failure following Hurricane Katrina on August 29, 2005, caused inundative flooding of New Orleans, Louisiana. Some areas remained under brackish water for about 3 weeks. Effects on Formosan termite populations were determined using independent in ground monitors to quantify foraging termite populations. Light traps were used to evaluate alate production the following spring. Initial reduction in the number of termite workers collected from monitors was observed. Termite populations have recovered the following spring and summer of 2006.

Species 1: Isoptera Rhinotermitidae Coptotermes formosanus (Formosan Subterranean Termite)
