AB  - Fire ants (Solenopsis invicta Buren in J Ga Entomol Soc 7:1-26, 1972), an 
      invasive alien ant species, first spread from South America to the United States 
      in the 1930s, the southern part of the United States by the end of the twentieth 
      century, Oceania, Taiwan, and China in the twenty-first century, and finally to 
      Japan and South Korea in 2017. As these ants have significant negative economic, 
      human health, and environmental impacts, the purpose of this research was to 
      accumulate cytogenetic information regarding fire ants and provide basic data for 
      developing management strategies for their control. Fire ants were collected from 
      invasive populations from Taiwan, Florida (USA), and Buenos Aires (Argentina), 
      and a native population from Puerto Iguazu (Argentina), their point of 
      origination, and analyzed with regard to chromosome number, morphology, and 
      polyploidy, silver-stained nucleolar organizer regions (Ag-NORs), and 18S rDNA 
      and telomere fluorescence in situ hybridization (FISH). The results showed that 
      (1) fire ants from invaded populations differed in chromosome morphology compared 
      to those from native populations; (2) the Florida and Taiwanese fire ant 
      populations evinced greater variability in chromosome numbers and polyploidy 
      variations; (3) the Taiwanese population exhibited significantly increased Ag-NOR 
      signals in interphase cells, with signal number significantly positively 
      correlating with distance from native populations; and (4) substantial diversity 
      of signals was also apparent following 18S rDNA and telomere FISH analyses. 
      Variation in these characteristics were hypothesized to be due to (1) the effect 
      of hybridizations and interbreeding between closely related species or 
      genetically distant populations, and (2) the potential effect of large amounts of 
      insecticides sprayed for pest control.
