To examine the impact of tropical rain-forest destruction on malaria, we conducted a year-long study of the rates at which the primary malaria vector in the Amazon, fed on humans in areas with varying degrees of ecological alteration in the Peruvian Amazon. Mosquitoes were collected by human biting catches along the Iquitos-Nauta road at sites selected for type of vegetation and controlled for human presence. Deforested sites had an biting rate that was more than 278 times higher than the rate determined for areas that were predominantly forested. Our results indicate that displays significantly increased human-biting activity in areas that have undergone deforestation and development associated with road development.
