I have the impression that I come with bad news. Bad news. The worst, the worst, the worst. The bad thing is that before the news is heard it will be old and we will get used to it.

In 1858 a special, never cataloged fly was found in the Polish region of Poznan, which was named Phytomyza gymnostoma. Then he has also been called Napozoma gymnostoma, but now he is again known for his name. The homemade fly, like the sword and the mosquito, belongs to the family of the Dipteros.

The gymnostoma Phytomyza had already been discovered in 1976 in Denmark, Sweden, Poland and the Mediterranean. In the 1980s, suddenly, we don't know why, Allium became a pest of species. First in the countries of Eastern Europe, then it headed west. He has already learned to cross the seas and has also appeared in England and the United States.

It attacks species of the genus Allium, especially the leek (Allium porrum). The female sticks with the opponent to lay the eggs and sucks the sweat, screwing the jaldre. Place the eggs in the foot of the leek, and the worms that are born from them will pierce inside the leek. To spend the winter, the pupa will become reddish. In spring, by April a fly will be formed that will lay the eggs and in early autumn the worms will return in the leeks of the next harvest. It attacks not only failure, but also leek (Allium schoenoprasum), onion (Allium cepa), garlic (Allium sativum) and applause (Allium cepa var). aggregatum).

I didn’t know that plague, and today, April 15, 2018, I’ve heard about it in photos taken by Mikel Arbelaiz in Oiartzun. In it you see the holes that have been made in the leeks and the red pupa that generates from all the worm until it is fly. Last year he also had an epidemic of plague in the series of pores. Therefore, in the absence of any other news, this fly has appeared in the failures of the 2016-2017 harvest in the Basque Country. Soon we will meet him all over Euskal Herria. Nice leek!

It's a very new fly that doesn't have access to Wikipedia, either in English or in French or in Basque.
