title: Population structure of Stomoxys calcitrans (Diptera: Muscidae) from nine regions of Thailand.
abstract: Starch gel electrophoresis of isozymes was used to estimate gene flow among nine populations of Stomoxys calcitrans (L.) (Diptera: Muscidae) from Thailand. Of the 13 putative loci, nine polymorphic loci were detected. Limited genetic differentiation among populations was observed (F(ST) = 0.060). The highest level of polymorphism was observed in flies from eastern Trat and northern Chiang Mai provinces (69.2%), whereas the lowest level of polymorphism was seen in flies from central Saraburi Province (23.1%). Gene flow between populations varied from 3.27 to 27.53 reproductive migrants per generation. Among the nine populations sampled, no correlation was seen between genetic and geographical distances showing that sampled S. calcitrans fit closely in the same cluster taxa. The electrophoresis of ten isozymes shows a genetic homogeneity of S. calcitrans populations at the scale of Thailand.
