Genetic differentiation of the honey bee (Apis cerana) in Thailand: evidence from microsatellite polymorphism
S Sittipraneed; S Laoaroon; S Klinbunga; S Wongsiri
Differentiation of the honey bee (Apis cerana) populations, collected from north, north-east,the central region and peninsular Thailand, and Samui island was examined using a polymorphism of three microsatellite loci (A28, A107 and A113). The results indicated high geneticdiversity in the mainland (north, central, northeastand peninsular Thailand) populations (Ho=0.40-0.46) but limited diversity in the Samui population (Ho=0.18) implying that genetic drift or founder effects may have occurred in this population. Intraspecific population subdivision was observed in Thai A. cerana (P < 0.0001 for both geographic heterogeneity and FsTstatistics). Five conspecific populations ofA. cerana in Thailand were allocated to four different groups; north and central region (A), peninsular Thailand (B), Samui island (C) and north-east (D).
