Bad Skeeter Thursday


Aedes aegypti

When an Aedes aegypti mosquito bites you, she – because only the females, which need blood as nutrients for their offspring, bite – will probe your skin with her proboscis as many as 20 times. Two pairs of sharp cutting edges, the fascicle, break the skin and then search for a blood vessel, withdrawing and re-entering until a suitable target is found. When the blood starts to flow, a salivary tube delivers a protein that stops it clotting. The mosquito holds still and then begins to suck; in 90 seconds’ time, she feels full, and stops. And then, if you are in parts of South and Central America and bang out of luck, you will have Zika.

It’s a horrible idea, and one that will draw shudders from anyone who has ever been bitten by a mosquito – which is to say, just about everyone. In the entire animal kingdom, the mosquito occupies a special place as receptacle for our hatred and disgust. Even the great and generous EO Wilson, author of the touchstone argument for preserving biodiversity, The Creation: An Appeal to Save Life on Earth, makes an exception for anopheles gambiae, which spreads malaria in Africa. “Keep their DNA for future research,” he writes, “and let them go.”

When Wilson thus hardens his heart, he speaks for us all. Where we revere and anthropomorphise such brutal predators as sharks, tigers and bears, we view these tiny ectoparasites as worthless, an evolutionary accident with no redeeming or adorable characteristics. No one ever had a cuddly mosquito. Thanks to malaria, they have probably helped to kill more than half of all humans ever to have lived. Today, according to the Gates foundation, the diseases they carry kill about 725,000 people a year, 600,000 of them victims of malaria. They are, as such, the only creature responsible for the deaths of more humans than humans themselves; we only manage to kill about 475,000 a year. This deadly work is carried out all over the planet: mosquitoes are found on every continent except Antarctica. And now there is Zika, which can lead to microcephaly and its associated physical deformities in unborn children, and for which there is no vaccine. This new horror has prompted fresh attention to the vexed question of how to defeat them. And that consideration leads to an unsentimental thought that we would entertain about no other creature: can’t we wipe them off the face of the Earth?

    Skeeters scrapped my move to Hawaii that I had spent weeks researching. There they have the Degue Fever going around thanks to these skeeters. My immune system is compromised due to the drugs I take for my RA, if I were to be bitten by a skeeter it could result in Dengue Hemorrhagic Fever and result in my death. Not worth the move.

    Still searching for a place to live.

    This latest mosquito scare is a good one. The baby’s born with the small heads…imagine a city full of people looking like that. It would be like living in a village of circus sideshow freaks. Did you ever see the movie “Freaks?” A black and white from 1932. I supposed it’s politically incorrect to refer to deformed people from circuses as freaks, as they were back then, but that’s what they were called.

    Hopefully, a vaccination will be found for this latest mosquito problem.

    Seems the nonsense in Oregon is finally over. I’m glad the government let those people ride until their occupation naturally fell apart. No need to murder and firebomb people like that. Just let them suffer from boredom and naturally unravel.

    The republican herd of candidates is melting away. Of course, we all knew it would. There can only be one.

    Various life forms have already been eradicated. Some are microscopic. Some not.

    Passenger pigeons.

    LIGO sees gravity wave.

      My, all the different groups who contributed have their news stories out. Los Alamos has one; that is of interest as my formative years were there. WSU has one as a professor and two grad students worked on LIGO; I talked briefly with one of the students. And there are the major players. Kip Thorne is one and a friend from undergraduate days at CalTech. There is a picture of him, who at 75 has a bald, possibly shaved, head and now a beard. Despite that I immediately recognized him.

    And so a total of 38 minutes to Sloan.

    Day 5: 86+38=124 minutes.
