Abstract:
Objective To analyze the genetic characteristics of ribosomal DNA ITS 2 region for differenciating anopheline mosquitoes within Hyrcanus group. Methods The ribosomal DNA ITS 2 region of both laboratory line and filed collected An. anthropophagus and An. sinensis as well as the field collected An. yatsushiroensis and An. lester i were amplified and sequenced. The sequencing data were then analyzed for the restriction mapping using Omega Sequencing analysis program. Results and Conclusion The length of the sequences of An. sinensis, An. anthropophagus, An. yatsushiroensis and An. lesteri are 472, 452, 456 and 456 bp respectively. The restriction mapping showed that there were different restriction digesting sites among the ribosomal DNA ITS2 region sequences from An. sinensis, An. anthropophagus, An. yatsushiroensis and An. lesteri . On the basis of the sequence differences among the anopheline species within Hyrcanus group, it is possible to develop new technique for genetic identification of anopheline mosquitoes.
