A GIS based information management system has been developed to help Urban Malaria Control in India. The basic objective is to develop a model to assist planning and implementation of a suitable control measure. The system can help in: (i) identifying high receptive areas in time and space domain; (ii) identifying risk factors for high receptivity; (iii)(More)
Barmer district of Rajasthan in Thar desert and hitherto a hypoendemic area for malaria came in the grip of a severe malaria epidemic during 1990. The epidemic occurred as an aftermath of floods, preceded by normal rains during 1988 and 1989 after a prolonged drought phase. The epidemic was spread over the whole district including Barmer town. Annual(More)
In biological ecosystems, population tends to fluctuate above or below asymptotic level or the 'carrying capacity'. Self-regulation is achieved by extrinsic, that is, environmental limiting factors and intrinsic, that is, physiological and genetic factors. In Malaria Anthropo-Ecosystem (MAES) which is much more intricate and complex system, Plasmodium being(More)
Diversity being one of the main characteristics of Malaria Anthropo-Ecosystem (MAES) is reflected in time and space. Temporal diversity of MAES generally may be divided into two types--long time periods usually on a global scale, and various local fluctuations expressed as malaria periodicity. Geographical confinement of MAES is determined by interactions(More)
The paper gives a brief history of malaria control in India through the National Malaria Control Programme (NMCP), National Malaria Eradication Programme (NMEP), implementation of the Modified Plan of Operation (MPO), strengthening of malaria control by launching P. falciparum Containment Programme (PfCP) and the Urban Malaria Scheme (UMS). Making reference(More)
Adaptations have been recognized as an essential facets of evolution. These broadly cover two types exemplified by change (adjustments) and that leads to creation of new species. The former is generally in response to environmental factors, while the others are genetic and heritable and enable the population to continue its existence. These are also(More)
Thoracic spiracle length and its index was examined for their ability to discriminate two ecological variants, type form and mysorensis, of Anopheles stephensi in the adult stage. The type form is exclusively domestic in all seasons, whereas the mysorensis variant occupies the outdoor niche during monsoon and postmonsoon seasons, with spillover into(More)
