Athens Breeding "Super Mosquitoes" 458
Chemisor writes "Air pollution and cramped housing conditions in Athens, Greece, are creating a new breed of mosquitoes which are bigger, faster, and can smell humans from farther away. The super insects have color vision and detect humans from 25-30 meters, which is about 50% farther than the ordinary mosquitoe. Beating their wing 500 times a second provides them with extra speed, and the larger bodies (by 0.3ug) presumably allow larger bloodsucking capacity." And in a similar vein (har har) New Scientist had a piece about what mosquitoes like or hate about people.

The better vision allows you to see more chicks to impregnate.
Just because you can't immediately see why evolution would lead to something - doesn't mean that it won't happen - it just means your not looking at the situation right.

The mosquitos in Athens might be becoming bigger and meaner, but you probably won't catch anything off them other than an annoying itch. However, if visiting tropical areas (or (possibly) NYC), it is essential to avoid mosquito-borne disease. Therefore, as well as covering up and DEETing as recommended as far as is feasible in the daytime, you should (i) bring, and use without fail, a mosquito net every night; (ii) take effective malaria prophylaxis. (Malaria is always unpleasant and frequently fatal: other such diseases (like dengue) can't be treated at all, so preventing bites is an important strategy.) Homeopathic "remedies" don't work. Consult a qualified physician before setting off.

"For instance, papilionid butterflies have six opsins, one UV, one blue and four LW..."
FYI SW, MW and LW are "short wavelength (SW, 300-400 nm), middle wavelength (MW, 400-500 nm) and long wavelength (LW, 500-600 nm)" - same source.

People that are immuno-suppressed whether by drug or disease would also be expected to have reduced response to mosquito bites.
Further, if your body has acclimated to the proteins in the mosquito's bite, it is quite possible that you'll find that when you travel you might respond to the bites of other species of mosquito that might have different/variant compositions to their saliva.

DDT is safe "when used as directed" (Score:1, Informative)
I read your links, and they contain numerous factual inaccuracies based on neo-nazi anti-environmentalist memes.
1) The USA banned DDT. No, we didn't, you can buy it today, and anyone who says you can't is flat-out lying. The USA banned DDT for agricultural use, which is quite reasonable since that use causes DDT-resistant pests to evolve very rapidly. DDT should be used for targeted pest control - and it still is, except in the many areas worldwide where agricultural use has destroyed its effectiveness.
2) Rachel Carson's book "Silent Spring" is the root of all evil and contains lies. No, the book contained some science that has since been disproved, but it's main message - that pesticides should not be used with a "more is better" philosophy, and that use of chemicals should be regulated when a global commons can be damaged - is still relevant. To quote Carson's book directly, "Practical advice should be 'Spray as little as you possibly can' rather than 'Spray to the limit of your capacity.'"
3) People are dying of malaria because the US banned DDT at Rachel Carsons' instigation. No, people are dying of malaria because DDT was used indiscriminately and now there are DDT-resistant malaria mosquitoes. There are other pesticides that have the same problem - because knuckleheads overused them agriculturally they are now useless for disease vector control. This is not a consequence of environmentalism - remember, environmentalists like organic agriculture!
People who tell you this shit just want to recruit more mindless drones for their army of environmental destruction. Their end goal is the elimination of all commons, particularly air and water , which they believe should be owned and not shared .
Read wikipedia's article on DDT if you want to know both sides of the story. But if you go in assuming "environmentalism is evil" or "corporations are evil" you have already given up your objectivity.

Well, you're wrong about that.
DDT should be a community-selected issue. If you're dealing with massive mosquito-borne diseases, there is a CBA that should be performed to see if the benefits outweigh the costs.
DDT use cannot be a community-selected issue because the environment is common to all.
Water runoff from one community flows into another community, seeps into aquifers that feed wells, drains into the ocean.
This seems to be a typical blind spot for "libertarians," even the smarter ones. The. Environment. Can't. Be. Privatized.
The issue is a lot more complicated than either of us can debate in this forum, but I believe the issues must be brought back up.
The issues have been brought up. Well, all of them except for the issue of how this chemical ravages the natural world.
I brought that up in another post, but I doubt anyone will address it, because there's so many other reasons why using DDT is a manifestly stupid idea.
If you wanted to bring up the issue of environmentalism vs. utilitarianism, you could have easily picked a better issue. For example, is it moral for governments to drain swamps, and destroy the indiginous creatures living there, in order to reduce fatalities from malaria and other mosquito-borne diseases? Instead, you picked an issue where the harm to the public is obvious.
Yet we can't use DDT in much of the world, and I believe that is a bigger problem that was created by fiat and mandate than by research and reality.
Yes, I'm so sad that the government banned a chemical that was wiping out entire species of birds, causing retardation, and contaminating the groundwater. Private industry and selfishness would have solved the problem so much better. "More of this terrible gibberish," to borrow a phrase from Hunter S. Thompson. Man, I wonder what would have happened if he had been locked in a room with Ann Coulter for a few hours. I guess the world will never know.

Farmers were using shiatloads of DDT on their fields.
Literally kilograms of the stuff per acre.
Rain + Field = DDT Runoff
DDT, in the quantities used in/around the home, is not terribly harmful.
Unfortunately, the hysteria over DDT gave it such a bad reputation that nobody will pay for it to be used at all, despite the fact that the ban is only on agricultural use.
