&gt; To address this challenge, Verily, an affiliate of Alphabet Inc, developed a mosquito rearing and sex sorting and release technology as part of its global Debug project.<p>Verily is formerly &quot;Google Life Sciences&quot; and currently Alphabet Inc&#x27;s research arm for life sciences.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Verily_Life_Sciences" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Verily_Life_Sciences</a>

&gt; <i>Aedes, Anopheles and Culex are found almost all over the world and are responsible for around 17 per cent of infectious disease transmissions globally.&quot;</i><p>If I understand that correctly, that is a <i>massive</i> number. I really like what these sterilization trials are producing. In my mind, it’s a lot safer than spraying chemicals across cities.

It is theorized there is no adverse effect from killing mosquito species. There is always a counter-effect. Typically it&#x27;s unpredictable. Mosquitoes FACILITATE transmission of bad stuff. I believe that if bad stuff is not transmitted, species evolve more slowly against pathogens. Species will still be exposed, maybe generations later through a scratch or otherwise. At that point, having never evolved a strong immune system the same animals will be less prepared. It&#x27;s not whether the American Indians were to die from European diseases, but when.

IIRC this is an Australian initiative: the basic work on the application of Walbachia to dengue, the formation of the world mosquito program, it&#x27;s an initiative grounded in Australian science.<p>yes, you will find &quot;we did it&quot; in China and Brazil and Vietnam and other places: The roots of this work go back to 2011 and before, at Monash University:<p><a href="https:&#x2F;&#x2F;www.monash.edu&#x2F;industry&#x2F;success-stories&#x2F;dengue" rel="nofollow">https:&#x2F;&#x2F;www.monash.edu&#x2F;industry&#x2F;success-stories&#x2F;dengue</a><p><a href="http:&#x2F;&#x2F;www.eliminatedengue.com&#x2F;about-us" rel="nofollow">http:&#x2F;&#x2F;www.eliminatedengue.com&#x2F;about-us</a>

How long did they measure this for, and how long is that relative to the lifecycle &#x2F; reproductive cycle of a mosquito? Is there any reason to believe the mosquito population won&#x27;t quickly (or if not quickly, then eventually) bounce back?

According to the WHO (<a href="http:&#x2F;&#x2F;www.who.int&#x2F;en&#x2F;news-room&#x2F;fact-sheets&#x2F;detail&#x2F;malaria" rel="nofollow">http:&#x2F;&#x2F;www.who.int&#x2F;en&#x2F;news-room&#x2F;fact-sheets&#x2F;detail&#x2F;malaria</a>)<p>* Malaria killed 445,000 people in 2016.<p>* Of those, 285,000 were children under the age of 5.<p>* There were 216 million cases of malaria in 2016.<p>That is a large city&#x27;s worth of children dying every year, and a large country&#x27;s population having severely reduced productivity.<p>And that is just one mosquito born illness.<p>The guaranteed human and economic benefits of wiping out mosquitoes, far outweigh any theoretical downside.<p>This group and other groups working to wipe out mosquitoes are truly doing humanity a great service.

What happened to the other 20%? If this is the part of the population that is resistant to the trial, then good luck in the coming years.

Out of interest, does anyone know how this affects ecological balance. Are the insects replaced by another species? How does this affect bird populations which rely on eating the mosquitos?

Will next generation of mosquitos be selected for greater fertility and more obscure sex-related features, thus making them harder to sterilize that way?

I never understood why the U.S didn&#x27;t just do the same sort of thing with poppies in Afganistan. Would have completely wiped out the Taliban funding.

Larger insects, small birds and amphibians eat mosquitoes. Shortage of food in a lower ring of the chain can escalate to the top as early as within a year and cause a severe depression in another part of the world for humans. As seen in all past instances, no matter how confident humans are, something goes awry when we try to cut something out of an ecosystem.

What is the probability of these sterile mosquitoes somehow evolving and reproducing on their own ?!<p>(So most of the batch is sterile and cant reproduce so cant evolve. But maybe just a single mosquito of the batch is &quot;faulty&quot; and can reproduce and is released anyway etc etc ?)

What are the unintended consequences? Surely, these mosquitoes are someone&#x27;s breakfast, lunch and&#x2F;or dinner. What happens when that species can&#x27;t eat?

As good as this is for preventing the awful scourge of human disease that mosquitoes cause - I still wonder what the knock-on effects of this will be, with respect to the overall loss of biomass and mosquitoes as a food source.<p>tldr: Mother nature does not like sudden vacuums in complex ecosystems, it gets ugly for somebody at some part of the food chain where we never expected it.

Always interesting when a 300,000 year old species decides a 50+ million year old species doesn&#x27;t need to exist anymore.<p>Tell me more ecologists...grabs popcorn.

If this isn&#x27;t the peak of human hubris I&#x27;m really not sure what is. What could go wrong?
bmcusick将近 7 年前
&gt; In an international partnership between CSIRO, Verily and James Cook University, scientists used specialised technology to release millions of sterilised male Aedes aegypti mosquitoes<p>This is so stupid. A population will recover from this in a single generation, because the second you stop releasing sterile males, the remaining males (no matter how few) can repopulate the species.<p>If you want to make a species of mosquitoes extinct (and I&#x27;m in favor of this, they serve no irreplaceable environmental purposes), the more effective method would be releasing males that only have male offspring.
