Summary
Mosquitoes bite the human and they bring many diseases for example, chikungunya and malaria. We want to wipe mosquitoes out for protecting from many diseases that mosquitoes carry, but we cannot remove mosquitoes easily because they have important roles in ecosystem. There are some ways to control the number of mosquitoes such as insecticides. According to Prof Hilary Ranson, an evidence base is need for getting rid of mosquitoes. The parasites which are brought by mosquitoes take about 10days to develop in human body. The mosquito’s lifespan is only three weeks so it needs to pick up the pathogen early in its life to pass it on. It will be effective to reduce the daily survival rate.

Opinion
For me, mosquitoes are only harmful insects because if I was bitten by them I feel really itchy and it is possible to suffer from some diseases. However, I know that such mosquitoes have important roles in the environment. So we should heed that the number of mosquitoes decrease too much.
I think that we should equip some items which give out ultrasonic waves or special odors which mosquitoes dislike and avoid. The method can achieve to protect from mosquitoes without killing them. It can be not only prevent from biting by them, but also need not decrease the number.
