Species identification of Culex quinquefasciatus mosquitoes is crucial for planning vector control program. The progress of molecular entomology tool supports a better understanding of the species identification. In the molecular study, it has grown ITS2 sequences which are used as a potential marker for species identification and phylogenetic analysis. The genetic diversity of Culex quinquefasciatus mosquitoes has been reported worldwide, but until now there has been no study of diversity of Cx. quinquefasciatus mosquitoes in Indonesia. The purpose of this study is to determine the genetic diversity of Culex quinquefasciatus as a filariasis vector in Central Java on the basis of ITS2 genes from ribosomal DNA. This study is done descriptively by collecting samples from filariasis endemic areas in Central Java. Results of the morphological and molecular analysis showed a difference of identification. ITS2 sequence alignment results of Cx. pipien complex from Central Java isolates have similarities with some isolates in many worlds. Phylogenetic analysis showed that ITS2 sequence of mosquitoes in this study is not monophyletic. The further results indicate the fact of introgression history ITS2 from Cx. pipien toCx. quinquefasciatus in Central Java. The introgression may occur before Cx. quinquefasciatus proliferate and spread in the Central Java region.
