Mosquitoes evolved to favor human blood in arid environments: study

The video discusses the Aedes aegypti mosquito, known for spreading yellow fever, originating from sub-Saharan Africa. It explores the mosquito's varied blood preferences, noting that urban mosquitoes are more inclined to bite humans. Researchers suggest this adaptation may be due to reliance on human water storage in arid regions. Climate change could exacerbate this tendency, potentially increasing the spread of tropical diseases.

Where did the yellow fever mosquito, Aedes aegypti, originally come from?

• South America

• Sub-Saharan Africa

• Southeast Asia

• Australia

What is the blood preference of yellow fever mosquitoes in rural areas?

• Strong preference for animal blood

• Strong preference for human blood

• No strong preference for human or animal blood

• Preference for plant nectar

Why are city mosquitoes more attracted to humans than animals?

• Due to the availability of human food

• Because of the dense population in modern cities

• Due to the lack of animals in cities

• Because humans provide more nutrients

What factor in arid regions influences mosquitoes' preference for human blood?

• Higher temperatures

• Lack of vegetation

• Dependence on human water storage

• Abundance of animal hosts

How might climate change affect mosquito behavior according to the study?

• It will make mosquitoes less likely to bite humans

• It could increase mosquitoes' willingness to bite humans

• It will have no effect on mosquitoes

• It will decrease mosquito populations
