CHAPTER 1 THE PROBLEM AND ITS SCOPE Rationale of the study There are more than 3 000 known mosquito species. However‚ of the 150 species that are potential vectors‚ only 30 are considered dangerous. The three genera Anopheles‚ Aedes and Culex‚ from three sub-families‚ are disease relevant. The epidemiology and the life cycle stages demonstrate the importance of climatic factors and that water is the essential environmental component for mosquitoes. The immature

Impact of amphibians on mosquitoes It is important for every ecosystem to maintain a balance between all the food chains so that nature can maintain its balance. Although natural ecosystems are under diverse challenges from anthropogenic activities‚ the ecological impacts of such processes often are unclear. Some “threats” may be worse than we think‚ but others may be less harmful. For example‚ invasive species disrupt the functioning

Background Mosquitoes are one of the most medically significant transmitters as they spread parasites and pathogens‚ which continue to have devastating effects on human beings (Maheswaran et al.‚ 2008). Mosquito-borne diseases such as malaria‚ filariasis‚ yellow fever and dengue cause extensive morbidity and mortality and are a major economic burden within disease-endemic countries . However‚ the use of chemical insecticides has been greatly impeded due to development of physiological

Abstract Mosquito repellents are essentially required these days. Mosquito coils are one of the cheapest and effective way of avoiding them‚ but this coils are made up of chemicals which can harm our health. So we thought about making a substitute mosquito coil that is not harmful to our health and that is the Anstor katol a natural and environmental friendly coil. Introduction Background of the Study: We chose this project because a mosquito coil made up from natural mosquito repelling

Different control measures are used routinely against mosquitoes and their larvae‚ including chemical (eg insecticide)‚ biological (eglarvivorous fish or pathogenic fungi)‚ environmental (e.g. land filling or drainage)‚ and personal protection (e.g. Mosquito repellents formulated as pills‚ coils‚ ointments‚ lotions‚ and sprays; and insecticide-treated
