The First report is that scientists found that if a certain bacteria infected mosquitoes, they didn't tranmist Dengue fever.
a second report says that surveys in Africa are showing that the mosquito that transmits malaria is also decreasing in number, for unknown reasons.
The scientists are uncertain as to why Wolbachia blocks the ability to transmit dengue, but Professor O'Neill said they have two theories: "The first relates to the immune system. The data suggests that the presence of Wolbachia boosts the immune system and helps the mosquito fight off the effects of dengue.
they don't know if this is from climate change, or if a bacterial or other disease has affected the mosquitos.
