Flying Insects Have Been Disappearing Over the Past Few Decades, Study Shows (theguardian.com) 178

Posted by BeauHD from the magic-tricks dept.
An anonymous reader quotes a report from The Guardian: The abundance of flying insects has plunged by three-quarters over the past 25 years, according to a new study that has shocked scientists. Insects are an integral part of life on Earth as both pollinators and prey for other wildlife and it was known that some species such as butterflies were declining. But the newly revealed scale of the losses to all insects has prompted warnings that the world is "on course for ecological Armageddon," with profound impacts on human society. The new data was gathered in nature reserves across Germany but has implications for all landscapes dominated by agriculture, the researchers said. The cause of the huge decline is as yet unclear, although the destruction of wild areas and widespread use of pesticides are the most likely factors and climate change may play a role. The scientists were able to rule out weather and changes to landscape in the reserves as causes, but data on pesticide levels has not been collected. The research, published in the journal Plos One, is based on the work of dozens of amateur entomologists across Germany who began using strictly standardized ways of collecting insects in 1989.

        I'm sorry to have to inform you that mosquitoes are an important food source for insectivorous birds. Hummingbirds, in particular. And Gnatcatchers [wikipedia.org]. Bats are also major predators of adult mosquitoes. Their larvae are an important food source for fish, dragonflies, crawdads, and smaller water-loving birds, as well.

          Bats, purple martins and other insectivores get a vanishingly small amount of their calories from mosquitoes - less than 1% of the stomach contents of bats. Mosquitoes are quite small and therefore not very calorically rich. Unlike midges and gnats, they don’t really swarm in a way that would allow insectivores to get a whole bunch in one swoop, so generally mosquitoes are providing fewer calories than the expense required to fly at them. Bats, martins and the like mostly end up eating moths and midges. Some species of dragonfly are mosquitovores but, again, not as a large percentage of their caloric intake.

          There are a handful of species that target mosquito larvae, which bunch up enough to be worth it. The aptly named mosquitofish is one such creature.

          But the saving grace even among mosquitofish is that they don’t care what species of mosquito larva they eat - getting rid of the handful that target humans will leave space for the hundreds of other species that exist in the US (let alone the thousands worldwide). There are approximately 3,500 species of mosquito and only about 40 that target humans. Most of the human targeting mosquitoes are invasive species in nearly all of their range, brought by humans. (Aedes aegypti and the Asian Tiger mosquito, for instance, shouldn't be found in the Americas...)

          Contrast that with the enormous chemical inputs we put into our lakes, streams and rivers in order to just control mosquitoes - we are surely inadvertently killing off other species of insects just trying to control mosquitoes. And when we drain a wetland because of mosquitoes, we impact far, far more species than even the worst case scenario of mosquito extinction.

          There have been a number of discussions among ecologists and the consensus [nature.com] is that wiping out human-targeting mosquito species is fine [theguardian.com]. Even E.O. Wilson, the famed biologist and campaigner for biodiversity, wants to kill them all [pri.org]. (He’s actually slightly more cautious, but basically wouldn’t spill any tears over eradicating human-feeding insects.)

In highly constrained environments, in this case [slashdot.org] a netted area where bats were only allowed to eat mosquitoes, they ate enough females to decrease the mosquito egg population by 30%.

      I hate mosquitoes but I found I solved that problem by moving far away from the Gulf Coast.

      I was chased out of a park once by a swarm of them. And some people are trying to get me to move back there. Bad timing. I told them you just had a hurricane and your homes are flooded and I don't even want to imagine what the mosquitoes are like. I think I'll stay up here in the mountains far away from any bayou.

      In between living in the swamp and living in the mountains I lived in the desert for a couple of years and I don't believe I saw a single mosquito in the desert. And I've only seen one palmetto bug (roach) since I moved out of the swamp and I'm pretty sure that one just hitchhiked its way across the USA- just like in that Lou Reed song.

      I hate most bugs especially roaches and mosquitoes but I made a mistake a few years back. When I moved into my current home I killed all the wasps with chemical weapons and they never came back. Some might call this a successful victory over stinging insects but I realized after the fact that I had done wrong. Unlike mosquitoes, wasps don't want to sting or bite humans. They just wanted to pollinate the plants. I regret killing the wasps.

      One type of bug I've never killed though is spiders and they've been good to me. One spider rid my house of some kind of tiny fly infestation - they weren't gnats or fruitflies - not exactly sure what they were but the spider built a web and caught them all and when they were gone the spider went away.

      Supposedly there are mosquitoes around here but I can't remember the last time one bit me.

      • The nice thing about long, cold winters - only a few months of mosquitoes, and they rarely venture far from a few known areas before old man winter eradicates them.

Hellava price to pay for a chemical that the insects will develop resistance to, just like weeds have developed resistance to Roundup.

These genes make plants themselves produce toxic crystals which destroy insect guts. Thus, farms don't have to spray insecticide anymore, the plants themselves ARE insecticide.

    Regardless, while the downward trend is clear, the 75% figure is bullshit. There was 50% variation over the first two years, and these major changes continue over time. The overall fall is still dramatic, just less than what is stated.

    • This number has floated around a few times this year.

      Personally I think if there is a decline, it's due to mankind's smash-and-grab of as much land as we can take, filling it with concrete and asphalt, then spraying pesticides everywhere. We hose down crops with insecticides as well, though that practice seems to be (I'm no farmer) waning. I don't like bugs in my house, and have pest control treat our lawns for fire ants - those guys are assholes - quarterly. Not trying to be a hypocrite... but you look at

  • PESTICIDES

    PESTICIDES

    You can't drop tons of chemicals engineered to kill insects into a biosystem, and NOT expect it to kill insects.

  • OK, I'm sorry, but I have serious problems extrapolating from one highly industrialized country in the middle of a highly industrialized continent to the entire world. The results they found in Germany are a basis to justify funding to see if the same holds true in the rest of the world, but not a very solid basis to draw a conclusion about what is happening in the rest of the world.

    Personally, I am somewhat skeptical of their conclusions because the number of bats and insectivorous birds which I see are

  • Germany is one of the most intensively human modified environments in the world. The current goal [www.bfn.de] of the Germans is to have 2% of their country be wilderness area by 2020 (it's currently 0.5%).

    Doing a wildlife study of Germany and extrapolating globally from that is fairly ridiculous. It might apply to a few other countries in Europe and maybe New Jersey in the US, but otherwise is useless.

  • "gathered in nature reserves across Germany"

    Couldn't the fact that it's in a nature reserve affect the outcome?

  • for the Northeast, especially Maine and Massachusetts. We're not bug scientists, but a lot of us noticed that something's been wrong for a few years.

    The states don't appear to be interested in funding any studies though. On guy actually said - I kid you not - if we don't study it, it doesn't exist.
  • I saw an article about this somewhere else recently, saying that here in the UK you just don't get the same amount of dead insects on your windscreen in the summer as you used to, although that was more anecdotal than evidence-based..
