Ectoparasites #2

This another part of Ectoparasites for the VT students of 2008 to study from for their finials. Since this is a very large section it has to broke up into parts to get everything down that we need to know so that we may pass our finial.

So how did you do on this section? I hope you did better then you thought that you would do. I know that it is helping me by doing this, since when I took one of the other test I got a good score on it and I will be trying them again later.
