Engineering Technology and Plant and Soil Sciences are teaming up to find solutions to the problem many Texans are facing - RIFA destruction of electrical and electronic equipment. Researchers are developing a transformer prototype that is both technically and economically feasible to reduce invasion of transformer boxes by RIFA.

Controlling Texas livestock losses due to fire ant infestation is the purpose of the studies being conducted in the Animal Science and Food Technology Department. Researchers are studying grazing patterns, behaviors and immune responses to see if fire ant density affects grazing times and patterns. The information will be the first known scientific data dealing with livestock grazing behavior and immune response.

Other research being conducted by Biological Sciences determines the conditions that promote worker execution of queens in fire ant colonies. If chemical messages (pheromones) could be delivered to worker ants, they would be stimulated to destroy all the queens, including the last queen in a colony.

In most areas populated by both harvester ants and RIFA, harvester ants are unable to compete. By developing a competition model between both species of ants, researchers aim to understand the effects of fire ants on native ants. Results of this study will be used in an overall model of the threatened Texas Horned Lizard.
