The microbe for malaria is carried by
A. Male Anopheles mosquito
B. Female Anopheles mosquito
C. Male Aedes mosquito
D. Female Aedes mosquito
Solution
Malaria is an infectious disease spread by mosquitoes and caused by different Plasmodium parasite protozoa bacteria. Malaria is a sickness that has plagued mankind for centuries. Mosquitoes preserved in amber over thirty million years ago provided the earliest evidence of this protozoan.
Malaria is a preventable and treatable disease. This life-threatening disease can be avoided or managed by taking specific preventative steps, such as:
Mosquito bites should be avoided.
Mosquito repellent is being used.
Camping near stagnant water should be avoided.
The bed is wrapped with a mosquito net.
Complete answer:
Option A: Male mosquitoes don't bite, thus they can't spread malaria or other infections. Adult females have a short lifespan, with just a small percentage of them living long enough to transmit malaria (greater than days in tropical areas).
So option A is not correct.
Option B: Only female mosquitoes eat blood to keep their body temperature up so they can lay eggs. Nectar is consumed by the males.
Malaria is spread by the female mosquito Anopheles.
Dengue, chikungunya, and yellow fever are diseases spread by female Aedes mosquitos.
So option B is correct.
Option C: Dengue fever is the most common viral infection spread by Aedes mosquitoes. Dengue fever poses a threat to nearly a billion people in countries.
So option C is not correct.
Option D: Dengue viruses are transmitted to humans by mosquito bites from infected Aedes species.
So option D is not correct.
So option B is the correct answer.
Note:
Female Anopheles mosquito causes malaria.
The mature Anopheles mosquito has a dark brown to black body that is divided into three parts: the head, thorax, and abdomen. The stomach part of the Anopheles mosquito species, unlike most mosquitoes, projects upward rather than parallel to the surrounding surface.
