We should not allow mosquitoes to breed in our surroundings because they

• A. Multiply very fast and contaminate food
• B. Are vectors for many diseases.
• C. Bite and cause skin diseases.
• D. Are not important insects.

Answer 1

The correct option is B Are vectors for many diseases.

Mosquitoes cause more human suffering than any other organism. Mosquito acts as a vector for the bacteria and viruses, responsible for the diseases such as malaria, dengue, encephalitis and yellow fever etc. When mosquito bites a human it causes severe skin irritation through an allergic reaction to the mosquito's saliva, this is what causes the red bump and itching.
