Malaria-Infected Mosquitoes More Attracted To Human Odor Than Uninfected Mosquitoes
Malarial parasite may change mosquito olfactory system, enhance attraction to human odor
Mosquitoes infected with the malarial parasite Plasmodium falciparum are significantly more attracted to human odors than uninfected mosquitoes, according to research published May 15 in the open access journal PLOS ONE by James Logan and colleagues from the London School of Hygiene & Tropical Medicine, UK.
According to the researchers, studies of mosquito behavior in the context of malaria transmission usually use uninfected mosquito subjects, and their study suggests that such behavioral studies may not always be representative of the behavior of infected mosquitoes. They conclude that understanding the olfactory changes underlying the behavior of these infected mosquitoes may help identify new compounds that could be used to develop mosquito traps for surveillance programs.
