Exterminating all mosquitoes could doom the animals that eat them.
Birds, insects, spiders, salamanders, lizards and frogs could lose their primary food source.
Wiping out a large part of the ecology could be a disaster.
- johnmaguire2013 10y agoThe parent specifically noted: > [...] and there are several researchs suggesting they serve no purpose on keeping the enviromental equilibrium (if they are gone, they won't be missed, the enviroment will be fine...) I'd love to see a source on this. The best I can find is this, which does indicate that some species could go extinct as a result: http://www.nature.com/news/2010/100721/full/466432a.html http://www.nature.com/news/2010/100721/full/466432a.html
- Symmetry 10y agoWhat I've read on the topic is that animals that eat mosquitos have lots of small flying insects to choose from if they disappear, so much so that you'd never notice the difference. Their role as pollinators is a bit more fraught but again there are still a few replacements standing by in pretty much every case.
- lowpro 10y agoAlthough he's missing references to the studies he mentioned, the point was animals that eat mosquitos would be fine without them, as they also eat other insects. Spiders come to mind.
- Myztiq 10y agoThere is a method for doing this. I can't seem to find the original article where I heard about this, but it was tested in some remote area in Africa and had a 90% reduction in mosquito population with just one application. Here is a more updated Zika flavored article about the same technique: http://www.cnn.com/2016/03/07/health/zika-florida-gmo-mosquito/ http://www.cnn.com/2016/03/07/health/zika-florida-gmo-mosqui...
- kafkaesq 10y agoI'm only aware of the test conducted in Brazil, which had a claimed 80% reduction rate: Oxitec, which is owned by Maryland-based Intrexon Corporation, tested its mosquitoes in the small Brazilian city of Piracicaba and said the reduced the number of mosquito larvae by 80 percent in one area.
- SomeCallMeTim 10y agoOR maybe killing all the blood-sucking mosquitoes would actually just be a net benefit. [1] [1] http://blog.chron.com/sciguy/2010/07/scientists-go-ahead-kill-all-the-mosquitoes-the-world-will-be-better-for-it/ http://blog.chron.com/sciguy/2010/07/scientists-go-ahead-kil...
- kin 10y agoAlthough I remember reading somewhere that mosquitos have a negative footprint on ecology. There's definitely a ton of research at the moment on mosquito control. There was another article on HN a few years ago on a device that tracks and kills mosquitos w/ tiny lasers that can't harm humans. Apologize for lack of source, I'll try and dig them up. EDIT: found it! wasn't too hard to find haha. And it seems other replies have already provided source on mosquitos and their net benefit: https://en.wikipedia.org/wiki/Mosquito_laser https://en.wikipedia.org/wiki/Mosquito_laser
- DicksenZuider 10y agoWhat does "negative footprint" mean?
- kin 10y agoAs in the do more harm than good to the ecosystem.
- huherto 10y agoSadly the mosquito laser is not happening yet.
- kin 10y agoBut a man can dream. It would be so nice to mount one on my shoulder as I travel through Southeast Asia
- notduncansmith 10y agoOther commenters have noted that there are enough replacements that these animals won't miss them. I'm curious, though, if the subsequent decrease in those species' populations (from making up a larger percentage of prey than when mosquitoes were available) would have negative effects.
- Brybry 10y agoBirds, insects, spiders, etc would probably benefit a lot more from humans no longer needing to spray insecticide to control mosquitoes. And mosquitoes would still exist -- just not the species that are regionally eradicated because they spread diseases (and many of which are invasive species such as Aedes aegypti).
