A preliminary map of the polytene chromosomes in Aedes aegypti has been prepared. The preparations were made from the salivary glands of the late 4th instar larvae reared at low temperature. The entire chromosome complement was divided into 45 zones. The chromosomes showed a meshwork of the contents wherein they have a tendency to adhere to each other so as(More)
The process of speciation, interrelationship of the species and the evolution ary trends in the family culicidae have been studied by the various workers using the banding pattern of the salivary gland chromosomes. Based on a comparison of the salivary chromosome maps the phylogenetic kinship among the various sp ecies of the genus Anopheles, studied so(More)
The salivary gland chromosomes of Anopheles stephensi from a local wild population in Nadasahib (Haryana) have been studied. The banding pattern is compared with the standard pattern of Anopheles stephensi (NICD strain). Differences in the free ends of the X-chromosome and the autosomal arms have been seen. These differences are both in the shape and the(More)
Experimental work pertaining to the molecular cytogenetics of malaria vector species of mosquitoes by the application of PCR technique has been carried out. The main objectives of the study included the sequence characterization of nuclear rDNA internal transcribed spacers 1 and 2 (ITS1, ITS2) and mitochondrial DNA COII gene as potential molecular markers(More)
Low complexity regions (LCRs) are a ubiquitous feature in genomes and yet their evolutionary history and functional roles are unclear. Previous studies have shown contrasting evidence in favor of both neutral and selective mechanisms of evolution for different sets of LCRs suggesting that modes of identification of these regions may play a role in our(More)
A standard map for the salivary gland chromosome banding pattern of Anopheles (Cellia) aconitus has been compiled. The banding arrangement of the species has been compared with that in another member of the Myzomyia group, Anopheles fluviatilis. Whereas the homologies of the X-chromosomes have the least correspondence, the 2R and 2L chromosomes have been(More)
The main objective of this study included sequence characterization of nuclear rDNA internal transcribed spacers ITS 2 and mitochondrial DNA CO II gene and 16 S gene fragment as potential molecular markers for studying genetic relatedness and phylogenetic kinship among five important species of genus Culex. After the extraction of genomic DNA from a single(More)
