in mainly tropical areas
The female anopheles mosquitoes carry malarial parasites.
Yes, mosquitoes thrive everywhere there are pools of water
It was dangerous because of yellow fever and malarial mosquitoes.
mosquitoes thrive in warm wet climates
No, mosquitoes thrive on blood from other organisms and therefore it is exploitation of animal derived products..
if the tree feels like attracting them, the yes.
Mosquitoes live in many different countries. They thrive anywhere where it is warm and humid. Iceland is one country where there are no mosquitoes. Every continent has mosquitoes except Antarctica.
Ronald Ross hypothesized that mosquitoes were injecting people with a small portion of contaminated fluid causing malaria outbreaks to spread. He used Culex mosquitoes in his studies that fed on Malarial patients but he needed to expand his study to other mosquito types in order to prove his theory.
Malaria is actually caused by tiny parasites that live inside the mosquitoes, not by the mosquitoes themselves. Plasmodium falciparum, Plasmodium vivax, and Plasmodium ovale are the 3 most common causes of malaria. (All three are commonly called "malarial parasites"--they are closely related species.)When a mosquito first bites a human, it injects some anticoagulants to keep the blood from clotting. If the mosquito happens to be infected with a malarial parasite, the parasite will be injected with the anticoagulants and will then infect the human red blood cells.
It is not exactly known who discovered that mosquitoes carried malaria. Based on available research, however, the WHO discovered mosquito borne viruses in the 1920's. A number of leading scientists and researchers concurred with their findings. As a result, the World Health Organization and the CDC are credited with these findings and reports.
In malarial infections the sexually mature parasite is found in the vector which is the Amophelus Mosquito.
