Helicoverpa armigera is an important pest of cotton and other agricultural crops in the Old World. Its wide host range, high mobility and fecundity, and the ability to adapt and develop resistance against all common groups of insecticides used for its management have exacerbated its pest status. An understanding of the population genetic structure in H. armigera under Indian agricultural condit...

Human settlement and migrations along sides of Bay-of-Bengal have played a vital role in shaping the genetic landscape of Bangladesh, Eastern India and Southeast Asia. Bangladesh and Northeast India form the vital land bridge between the South and Southeast Asia. To reconstruct the population history of this region and to see whether this diverse region geographically acted as a corridor or bar...

Five Indian geographical populations of Drosophila melanogaster were analyzed for their genetic divergence of life history traits. Clinal variations were observed for body weight, ovariole number, and four pre-life history traits (i.e., fecundity, hatchability, viability, and duration of development). Rearing populations at different growth temperatures shows that the variations among wild flie...

The vir genes are antigenic genes and are considered to be possible vaccine targets. Since India is highly endemic to Plasmodium vivax, we sequenced 5 different vir genes and investigated DNA sequence variations in 93 single-clonal P. vivax isolates. High variability was observed in all the 5 vir genes; the vir 1/9 gene was highly diverged across Indian populations. The patterns of genetic dive...

The origins of the nearly one billion people inhabiting the Indian subcontinent and following the customs of the Hindu caste system are controversial: are they largely derived from Indian local populations (i.e. tribal groups) or from recent immigrants to India? Archaeological and linguistic evidence support the latter hypothesis, whereas recent genetic data seem to favor the former hypothesis....

AIM To study the hematology and serum biochemistry parameters of Indian spectacled cobra (Naja naja) and Indian rat snake (Ptyas mucosa) and to evaluate the differences in the same between captive and wild populations. MATERIALS AND METHODS Animals were categorized into four groups, viz., wild Indian spectacled cobra (n=10), wild Indian rat snakes (n=10), captive Indian spectacled cobra (n=10...

An early telemedicine project involving NASA, the Papago Tribe (now the Tohono O'odham Indian Nation), the Lockheed Missile and Space Company, the Indian Health Service and the Department of Health, Education and Welfare explored the possibilities of using technology to provide improved health care to a remote population in southern Arizona. The project, called STARPAHC (Space Technology Applie...

The gut bacteria exert phenotypic traits to the host but the factors which determine the gut bacterial profile (GBP) is poorly understood. This study aimed to understand the effect of ethnicity and geography on GBP of Mongoloid and Proto-Australoid tribes of India. Fecal bacterial diversity was studied in fifteen tribal populations representing four geographic regions (Assam, Telangana, Manipur...

In India, diabetes is endemic, linked to urbanization (1), and its dispersed migrant populations show a particular vulnerability (2,3). For example, in Britain, diabetes is more frequent among Indian migrants than in the general population (4,5), but reported rates appear to equal those in India (6), although diverse dietary and cultural habits across India are also likely to have an impact (7)...
