I had a lot of fun building this marketing website for Debug back when I worked at Verily in 2016.

Crazy that despite their progress behind the scenes, they appear to have not touched this website since.

I probably spent a little too much time tweaking the CSS to get the mosquitoes to not overlap the text on various viewport sizes :)

The domain name reminds me of the venerable DOS "debug.com" command, which managed to combine an interactive and scriptable debugger, assembler, and disassembler into a program weighing a few kilobytes. I spent many long hours in my youth using it to reverse engineering copy protection on games. I really wish we had a similar tool for the modern era.

My understanding (very informal armchair) is that someone could relatively easily wipe out aedes aegypti using a gene drive with a sort of sex-selective infertility:

Release a few thousand females carrying a gene drive that produces all infertile males, and all fertile females (who all also have the same gene due to it being a gene drive). Every generation, there are more and more infertile males, and more and more fertile females carrying this extinction gene. After several generations (a.k.a. a few years), the population collapses completely.

I vote yes.

A less high-tech way to reduce mosquitoes in your own back yard is to set up an attractive nesting location, such as a bucket filled with plant cuttings and water with protection from the rain, and putting Bti(Bacillus thuringiensis subspecies israelensis) in it. Bti will kill the larvae after they hatch. You can buy Bti pretty easily, usually in a dehydrated form called mosquitoes bits or mosquito dunks. Make sure to remove other potential nesting locations or add Bti to them too.

This is a great initiative. HOWEVER, THIS IS NOT NEW. This has already been tried and tested successfully in Singapore.

Maybe a dumb question, but why release them back? Why separate and raise sterile males when you could kill off both male and female and be done? Is the idea that introducing sterile males back into the population has a compounding effect?

Is this safe? I hope it doesn't affect the ecology in worse ways we won't foresee, it has happened before

Heh after reading that title card I thought this was going to be a mosquito based software bug analogy. I expected a description of how to write software that resulted in more "good bugs" that might facilitate finding other bugs somehow. Now I'm a little disappointed

I don't understand non-breedable part, mosquitoes are a part of a food chain as everything else, surely you don't think eliminating them will have no consequences?

(probably the other way around, but what's the fun in that)

The Krogans got punitively infected with the genophage to drastically reduce successful births after their rebellion.

Cool project! And, surely, absolutely not what I expected to see when I clicked the domain "debug.com".

For those unaware, the US govt has run a similar project in Central America and most recently Panama (think Darien Gap) to eradicate the New World screwworm fly. They use similar techniques.

I think supporting the predators of mosquitos is the better solution.

We should go out of our way to avoid spraying insecticides in our lawns and other spaces. The lifecycle of the mosquito is much more rapid than that of fish, spiders, dragonflies, bats, etc. If you regularly nuke an area with insecticides, the mosquito population will have a lot less pressure to deal with.

The past 2 years in CA have been brutal for these invasive mosquitos. They bite all day and literally swarm around my house. It'll be 1pm on a hot day and they are all over.

I know this isn't attainable for most of the world but sharing in case someone else is similarly frustrated. I ended up spending $500 on a trap w/ co2 tank and it has been a life changer. I don't even see mosquitos anymore. Refilling the co2 is quite annoying and expensive ($20 every other week) and you have to clean out the 100s of bugs from the trap net but I can literally sit in my backyard all day again.

I wonder if a cheaper trap could be designed to give everyone little bubbles of safety.

Why does releasing infertile males prevent the fertile males from reproducing? Are mosquitoes pair-bonding??

Interestingly, many other insects need blood to reproduce because they cannot produce some of the required proteins on their own. Some common flies do this too, including horseflies, black flies, sand flies, and others. Some famously transmit disease, like the tsetse fly.

It makes me wonder if this kind of technology is deployed, where should the stop line be? And I don't think it's a trivial question.

I love this idea but I feel scared as well; who knows what we discover when we wipe these bugs out...

I was about to ask how the mosquitos survive long enough to make an impact if they can't "bite". I looked it up, and apparently male mosquitos survive off of nectar and are actually pollinators.

Eliminating mosquitoes sounds great to me on the surface, but I wonder if it will have any adverse effects on any plants that rely on them for pollination, or if it's expected that there are plenty of other insects ready to fill any void they leave.

This is cool, but wasn't this a "Verily" project about 10 years ago? What is new here and what has happened since then?

Quick NPR Short Wave episode about this https://www.npr.org/2026/05/27/nx-s1-5806598/disease-science...

Large scale geo and bio engineering projects like these always worry me because of the potential for second order effects: is there wildlife that depends on these mosquitoes? Will a worse bug fill the resource void? Will a random mutation in the bacteria have adverse effects? What keeps the bad bugs from coming back from tiny populations in relatively short order because we can’t keep releasing new sterile males forever?

Hopefully all of these concerns have satisfactory answers, but the reference to it being a 1950s idea isn’t inspiring. Nuclear powered cars, widespread asbestos use, leaded gasoline, Freon… environmental impact wasn’t as big of a concern back then to put it mildly.

COVID proved that we can produce safe and effective vaccines extremely quickly if we actually try: so why not focus on that?

The symmetry is amusing. This is really fighting fire with fire.

Mosquitoes are a vector that spreads disease-causing germs to a population. The proposed solution is to use different mosquitoes as different vector that spreads a different disease-causing germ to a different population.

Interesting. What is the long term effect? Do the bad mosquitoes breed back to a sizeable population after some time and again good mosquitoes have to be injected in the target environment to keep the growth of bad mosquitoes in check?

Unless there's been some new announcement that I don't obviously see here?

great use of the domain

What a domain name !

The critics have valid concerns. Verily / Google would be deploying 10-15x the local mosquito population (enough to black out the sun). The deployments are contaminated with females, as any natural product would be. And it’s possible that the mosquitos could develop Wolbachia tolerance, since mosquitos are quick to develop tolerance due to their breeding patterns and lifecycle.

Don’t be so quick to rush to a verdict. We are still living with invasives we introduced with the same good intentions.

The current news:

Google wants to release up to 32M good mosquitoes California and Florida

(perhaps one of these should be the submitted link)

No thanks. I’m very concerned some short term thinking behind a plan to alter the biology of our environment will have various side effects no one anticipated. It has happened many, many times before. Same with geo engineering in general - hard to trust the incentives, competency, and long term side effects.

This is a Google project?

The effect of this could make some mostly uninhabitable areas more habitable.

This project has like 10 years of history behind it right? Originally powered by Verily Life Sciences (inside Alphabet's Google X research div)

When I read the heading I thought it was about software bugs and really wondered for a microsecond how can we stop bad software bugs with good software bugs. :)

For too many seconds I really did think this was an initiative using the metaphor of good/bad mosquitos to make the case that they were going to release "good" malware (bonware?) into the internet ecosystem in order to disable bad malware or install security patches, or something.

I might be an idiot.
