ants have long been known to be a major pest and have recently
attracted renewed widespread attention due to the invasion of Solenopsis species, especially S. invicta,
into many countries in Asia and Australia. Here, we surveyed fire ant
specimens in Thailand with the aims of studying their colony biology
and population structure. We sampled 38 colonies distributed in
agricultural and urban areas throughout Thailand for species
identification and found that all were S. geminata.
We further genotyped 13 microsatellite loci from 576 workers from 23 of
these colonies. Analysis of this genetic data revealed that all
colonies were polygynous with only a few queens. Queens from the same
colonies were highly genetically related. Population structure was
partitioned into two clusters. Pairwise FST
values revealed very high genetic differentiation between colonies
suggesting low gene flow among populations. This result suggests that
queens were locally mated and founded colonies by a budding strategy.
Isolation-by-distance among local populations was not significant.
Key words: Polygyne, Social form, Relatedness, Microsatellite, Metapopulation model.
