Today, I have been doing my milestone, and i also have researched the three kinds of mosquitoes.

//**4 types of mosquitoes : Aedes aegypti, Aedes albopictus, Culex pipiens, and Ochlerotatus triseriatus**//

This laboratory has broad interest in mosquito genetics and genomics, with a primary goal of understanding the molecular genetics of disease transmission by mosquitoes. Most of their work involves the Yellow Fever and Dengue Fever virus vector //Aedes aegypti//. This includes development of genetic markers and the genetic dissection of phenotypes associated with competence to transmit pathogens to vertebrates. Among pathogens we work with are Dengue virus, the human lymphatic filariasis parasite //Brugia malayi//, and the avian bird malaria //Plasmodium gallinaceum//. They are also conducting studies with the Asian Tiger mosquito //Aedes albopictus//, the West Nile virus vector //Culex pipiens//, and the LaCrosse virus vector //Ochlerotatus triseriatus//. ||

I found some pictures of mosquitoes

I have made some questions about researching mosquitoes using SEM.

First of all, I see that we can move the point of the lense to see other parts of the mosquitoes. But is the mosquito going to fit there? How minimum size should the object be?

Next, I have found that wet objects can not be observed by SEM. That was one of SEM's limitation. Since mosquito is a creator moving and alive, it has blood which is liquid. So, I guess we have to suck all the blood and liquid from mosquito and dry them. But my question is, doesn't the mosquito's shape of any parts destroy by drying or sucking all the blood out?

Final question, I heard that we can measure with some magnification, so we can see mosquitoes closer. How close can we see? What is the minimum and maximam magnification of SEM? ||
