as bugs come for its mulberry trees, a city wraps itself in flypaper

TEHRAN —
It\'s usually around noon, later.
The summer sun is roasting the Iranian capital, and they appear: thousands of tiny whitefwhitef that look ubiquitous, but are particularly thick on the leaves of mulberry Berry, Tehran\'s iconic tree.
The flies were originally found in southern Iran and have found their way to the capital in recent weeks and are now a complete flyon pest.
They are so thick that it seems that everyone in the city has accidentally swallowed one.
It was a morning ceremony to clean up the body on the window frame, where many flies died.
\"When I was working on the top floor of my building, my head was in the clouds,\" said Ali Mesgaran, the building manager . \".
\"It\'s in the clouds of flies.
Retired civil servant Mary am Turkmazar said she wore sunglasses even in the House to prevent flies from entering her eyes.
She said: \"The authorities say the fly is harmless, but my eyes have been red since the fly appeared.
The fly is too small to miss.
Houria Maleki, 50, said: \"I took a bite from the Apple the other day, just after I swallowed it, I realized there were flies on ityear-
Old residents of Tehran
She and her husband installed nets on the windows to prevent pests.
\"We have mosquitoes, we have normal flies, but no one knows where these flies suddenly come from,\" she said.
Well, not exactly.
In a windowless room at the headquarters of Iran\'s Ministry of Environment, 43-year-old Ali nardelhiyear-
The old entomologist who usually specializes in butterflies has been studying fly problems.
The flies come from southern Iran, where they have been a problem, but they have moved north as the climate warms, he said.
They appeared in Tehran three years ago, and more people have appeared every year since.
Sir\'s question.
Naderi, who traveled across Iran and found at least 15 new species of butterflies, is working on how to fight billions of whitef in the capital.
He sighed and said he would rather fight the goats because they were the reason he thought caused a decrease in the number of butterflies across the country.
When goats graze on the Iranian highlands, their determination is to root out the plants on which butterflies live.
\"I hate goats . \"
Said Delhi with a smile.
\"Whitef is not very interesting to me.
Most people in Tehran never thought of butterflies and goats.
Long ago, both species left the vast city on the slopes of the alberds mountains.
Chaotic buildings and poor planning have turned Tehran into a traffic jam and pollution levels often break international records. Rows of high-
The rise blocked the boom from the West.
With the blocking of natural air flow, the number of dust particles in the air increases.
It\'s terrible for humans, but great for whitef.
\"With the temperature rising, you have the ideal conditions for whitef . \"Naderi said.
He said that the icing on the whitefcake cake is all the mulberry trees, which are constantly being wiped out by greedy bugs.
Officially, whitef is known as the hem worm, a large group of insects that rely on nutrients from their hosts.
\"Some take juice from the leaves;
Other people suck blood or suck away the internal organs of others . \"Naderi said.
Flies also discharge a sticky substance, which provides an ideal breeding place for many varieties of fungi. Mr.
Naderi said their only enemy, bugs like butterflies and goats, did not survive in the modern days of Tehran.
After several months of research
Naderi concluded that there are only two ways to eliminate pests: pray for a long, cold winter to kill all the eggs, or cut down mulberry.
He admitted that there had been no such winter in Tehran for at least a decade, so he reluctantly chose a second option.
\"We should cut down all the santrees in the city,\" he said . \"
\"I don\'t see any other way.
\"The sangberries in Tehran can be traced back to the time when Tehran was a city of ordinary houses and many gardens.
Over the years, they have played an important role: Researchers at the University of Tehran have found that they are one of the most efficient natural air purifiers in the city.
Of course, no city official is willing to take responsibility for spending cuts.
\"So it comes down to this,\" he said . \"
Naderi, \"We just have to learn to live with flies.
Officials from the city and province of Tehran attended the meeting as servants and advisers to the people.
As public demands for a solution to the problem rise, they have to take action.
Because it is clear that the problem of solving pollution and dust is beyond their wage levels, and the release of millions of bed bugs can lead to more complaints, officials have come up with an elegant and simple solution that may stem from childhood memories: flying paper.
But it\'s not just a ribbon that hangs on the ceiling like a ribbon.
Yellow letter paper-
This color is known to attract insects.
Be placed anywhere in town to fight whitefwhitef.
The army of municipal gardeners in Tehran, mostly Afghan migrants, were sent to tie yellow ribbons around santrees and almost any other tree.
In Tehran, trees with grass paper are everywhere on the streets.
Now there are a lot of dead flies stuck on it.
At Eram Park in the west of the city, a group of Afghan gardeners are having breakfast.
They say flies don\'t bother trees unless they start to die because it means more work.
Samiollah Hakimi, 18, said: \"We were told to put yellow ribbons on the tree . \" He came to Iran a week ago.
\"We thought it was interesting.
These people explain that in neighboring Afghanistan, people only treat things the way they do.
\"Yes, there are flies,\" said Mohammad Niazi, 23 . \".
\"The people here are very sensitive --
What\'s the fuss about the little things on the leaves?
