Mosquitoes are insects that transmit a blood parasite that causes diseases. In the past, mosquito-borne disease presented sever problem to different parts of the world. Researchers began to study mosquitoes by its taxonomy, morphology and internal characteristics of the insects for obtaining the reason why they cause such disease.
One of the disease caused by mosquitoes is malaria, malaria is not the lone mosquito-borne disease that caused troubles during the early times. But the leading cause of malaria infection is the humans that are affected with the parasite. And with the appearance of efficient medicine, it has helped in improving our understanding of mosquitoes and the infection it causes.
One way of preventing malaria is by killing the local mosquito population, and health workers responded the malarial outbreak by spraying DDT. When it was first sprayed on a local mosquito population, the population goes into abrupt decline. Due to over use, DDT became ineffective quickly. DDT resistant mosquito were first detected on India in 1959, mosquito population increased rapidly even though spray programs were implemented in just months of being affected by it.
DDT resistant mosquitoes exist at low frequency in the global mosquito population. When a local population is sprayed, a strong force of selection in favor of the resistant mosquitoes is immediately created. It is only a matter of time before resistant mosquitoes will dominate the mosquito population.
Background of the Study
In recent surveys, Dengue, a vector-borne disease, is considered one of the most dreaded health problems worldwide. In report published by the World Health Organization (WHO), dengue epidemic has become widespread in more than 100 countries in Africa, America, Eastern, Mediterranean, Southeast Asia and the western pacific, affecting more than 2500 million people or about 2/5 of world population. In the Philippines, 70000 dengue cases were reported from January to September this year. Though it is 25% lower compared to the cases of the same period last year, the government vows to intensify its campaign against dengue. A recent study by Professor Fernando Garcia from the College Of Public Health, University of the Philippines Manila (UPM), an examination of the spatial factors of dengue cases in Quezon City, a geographic information-based approach, showed that GSIS can help the government in the quick identification of dengue high risk areas. In order to effectively control dengue disease, it is important to understand the vector of the Aedes mosquitoes and the contributing factors that influence its occurrence and recurrence, said Professor Garcia.
On the other hand, population density is not significant to dengue occurrence. Based on the data gathered, both high densely populated and low densely populated areas in Quezon City are recorded high dengue incidence. In fact, many areas with high dengue incidence were low densely populated barangays, added Professor Garcia. They also examined...
