RAPD Analysis on Different Nests of Camponotus nicobarensis

The Genetic diversity and phylogenesis of Camponotus nicobarensis Mayr from five different nests were analyzed by Random Amplified Poly-morphic DNAs(RAPD) technique.61 RAPD markers were obtained,which were amplified by 15 random declainer primers.Among them,23 marker with 37.70% polymorphisms were detected.The results indicate that the Nei's gene divesity(H),and Shannon's information index(I) was 0.122 0 and 0.185 8,respectively.And the genetic distance among which was varied from 0.851 5～0.948 5,with distance coefficient between 0.051 6～0.160 3.Based on genetic distance and geneticsimilarity,molecular phylogenetic tree of Camponotus nicobarensis Mayr has been constructed by using UPGMA method.The results showed that genetic relationship of 5 populations of Camponotus nicobarensis Mayr correspond to geographic distance.
