Researchers Find Effective Biological Control for Non-Native Fire Ants

(Beyond Pesticides, June 29, 2022) A virus present in low levels in the United States is effective at managing populations of non-native fire ants, according to research. Although only focused on one particular fire ant, Solenopsis invicta (the red imported fire ant), the study published in the Journal of Invertebrate Pathology shows promise for gardeners, land managers, and the public looking to manage fire ants without the use of hazardous chemical insecticides. As climate change and global trade facilitate the spread of dangerous non-native species, there is a strong need for new and cutting edge approaches that target these pests without significant harm to public health or the surrounding environment. Prior testing by scientists involved in the current study had indicated that Solenopsis invicta virus 3 (SINV3), found sparsely throughout the U.S., was able to successfully infect and kill imported red fire ants in a laboratory setting. Scientists find that the virus modifies the behavior of worker ants, impeding their ability to either acquire or distribute food to larval ants. Worker neglect caused by the virus results in high larval mortality and degraded queen health, eventually leading to colony failure. Based on the promising laboratory data, scientists initiated a field […]
