SourceThe total flying insect biomass decreased by more than 75 percent over 27 years in protected areas, according to a study published October 18, 2017 in the open-access journal PLOS ONE by Caspar Hallmann from Radboud University, The Netherlands, and colleagues.

To gain a better understanding of the extent and underlying causes of insect decline, Hallmann and colleagues measured total flying insect biomass using Malaise traps, deployed over 27 years in 63 nature protection areas in Germany. They found that the average flying insect biomass declined 76% (up to 82% in midsummer) in just 27 years in these locations. Their results align with recently reported declines in vulnerable species such as butterflies, wild bees and moths, but also suggest a severe loss of total flying aerial biomass, suggesting that the entire flying insect community has been decimated over the last few decades.

Our results document a dramatic decline in average airborne insect biomass of 76% (up to 82% in midsummer) in just 27 years for protected nature areas in Germany. This considerably exceeds the estimated decline of 58% in global abundance of wild vertebrates over a 42-year period to 2012 [56, 57]. Our results demonstrate that recently reported declines in several taxa such as butterflies [7, 25-27, 58], wild bees [8-14] and moths [15-18], are in parallel with a severe loss of total aerial insect biomass, suggesting that it is not only the vulnerable species, but the flying insect community as a whole, that has been decimated over the last few decades.
And down the chains.
Actually it is a threat to humans... stop dismissing facts you should have learned in kindergarten.
Indeed.
Even with all the knowledge in the world available at your fingertips, you produce this drivel?

Damn, the delicious insect eating plants will go extinct what are we gonna eat.

Is the cost of frogs gonna go up?
...
The meat on cows will get less tasty because they will do less swatting of insects?
Instead of oh no there are less annoying insects now, look into why it is so, what do they eat and is there enough for them to eat, where to live, etc.
In the meantime I'm seeing the usual animals around as always. If anything the tiny spiders with their webs everywhere are annoying, maybe that's where insect ended up, feeding spiders.
