Meetings are held in the Zilker Garden Center, 2220 Barton Springs Rd., Austin, TX, 78746 at 7:00 PM on the fourth Monday of each month except December.

Feb. 25, 2019, 7 PM meeting: Tawny crazy ants and their microsporidian pathogens: the biology of an invasion and the prospects for its control, presented by Edward LeBrun, Ph.D.

Tawny crazy ants are an environmentally damaging invasive species introduced from South America. These ants are currently spreading throughout the Gulf Coast region of the United States including Travis County. In this talk I will describe some of the basic biology and ecology of this invader, its impacts upon the natural systems it invades, its interaction with the current regionally dominant invasive ant, imported fire ants, and ongoing work towards sustainable control of this antís populations in natural environments.

I am a Research Scientist in UTís Department of Integrative Biology based out of the Brackenridge Field Laboratory. I did my PhD work at the University of Utah working on ant community ecology. I have been working on invasive ants and their natural enemies in South America, Texas, and California since 2004.
