Today’s Enemy

And she can lay 1000-3000 eggs.

The Brown Dog Tick

Rhipicephalus sanguineus, the brown dog tick

The interesting thing about this one is that it is found all over the world.  It can live its entire life indoors as well. One woman in Colan, where I just was, reported seeing a wall of a local house infested with hundreds of the things.

What I want to know, and what no one has been able to explain to me as of yet, is why this tick will go after dogs so aggressively, but tends to ignore other animals. What is it in the signals that a dog gives off that attracts this particular tick? Or what does this tick have that say, a deer tick doesn’t? The deer tick, Ixodes scapularis, is our usual suspect for the transmission of Lyme disease.

And now, the rankings of the most popular posts for the last 90 days. Clearly, Brigitte is leading the pack, followed by the life cycle for Trypanosoma cruzi. I am going to have to find a way to get Brigitte (of the 60’s, via a time warp) to talk to you about vector-borne disease. Sophia of the 60’s agreed to do it, but she didn’t fit in our time machine.
