Genetic Diversity and Gene Flow among Stable Fly Populations, Stomoxys calcitrans (L.) in Thailand

ABSTRACT Isozymes from five wild-caught Stomoxys calcitrans (L.) were compared using starch gel electrophoresis to estimate the rates of gene flow between and among S. calcitrans populations from five different geographic regions of Thailand. Among ten enzyme systems, 13 putative loci and 10 polymorphisms were detected. Limited genetic differentiation among the five populations was observed as indicated by the low F ST (0.078). The highest percentage of polymorphic loci was observed in eastern Trat province and northern Chiang Mai province (69.2%), whereas the lowest percent polymorphism was seen in south-central Saraburi province (23.1%). Gene flow between populations varied from 6.16 to 15.38 reproductive migrants per generation with no fixed genetic differences detected. Among the five population samples, no correlation was seen between genetic and geographical distances showing that sampled S. calcitrans fit closely in the same cluster taxa. The genetic and epidemiological ramifications of these findings are discussed

Stable Fly (Diptera: Muscidae) Distribution in Thailand

ABSTRACT Diurnal sampling of stable flies (Stomoxys spp.) was carried out in ten localities throughout Thailand in 2007. Vavoua traps were used to lure and capture flies in ten provinces of the country, representing four major ecological settings: six small local dairy farms; two large industrial dairy farms; one national park; and one wildlife conservation area. Six species of stable flies were identified: Stomoxys calcitrans (91.5%), S. bengalensis (4.7%), S. uruma (2%), S. indicus (1%), S. sitiens (0.6%) and S. pullus (0.2%). The number of stable flies collected differed significantly among different collection sites, with greater numbers from dairy farms (χ 2 = 360.15, df = 3, P< 0.05)
