In Yimin Lane, Youbei Avenue, Baipaifang Street, Xicheng District, Beijing, caterpillars flooded the streets of Yimin, and several large trees were covered with caterpillars, which crawled around, nibbled away the leaves, and continued to fall on people with the breeze. This phenomenon has become a major problem for residents. On September 14, after the Beiqing-Beijing headline reporter gave feedback on this phenomenon to the relevant departments, the garden department has sent people to spray pesticides for emergency disposal.
"The trees downstairs are crawling with caterpillars, which look scary, and I hope someone can take care of it." On September 12, some residents broke the news through self-media, describing a scene seen in Yimin Lane in Xicheng District.
According to the clues provided by the resident, on September 13, a Beiqing-Beijing headline reporter came to Yimin Lane in the Youbei Avenue community and found several large trees full of caterpillars that residents reported.
Mr. Zhang, a resident, said that bugs can often be seen on several large trees in Yimin Lane, but this year's caterpillars are the most exaggerated than usual.
Mr. Huang, who has lived in the hospital for many years, told reporters that this caterpillar began to appear on the trees in the courtyard two or three months ago, and has reached its peak in recent days.
"I put the electric car under the tree the other day and found a lot of bugs, and now I have to clean up and clean up the bugs before I go out." And you have to be careful when walking, stepping on the feet is sticky. Mr. Huang said that he had asked the staff of the landscaping department and heard that this was a bug called the "American White Moth", "When the medicine was not completely removed in the early stage, they developed very quickly, and now the three ailanthus trees have been eaten, you see, the small apricot trees downstairs have no leaves." ”
Beiqing-Beijing headline reporter saw at the scene that only one or two branches of the 3 ailanthus trees with leaves more than 10 meters high in the courtyard remained, and the dark brown branches looked far away, like a layer of white hair, and this layer of "white hair" was actually a white bug.
Bugs crawled around on tree trunks and branches. The bug is about 4 centimeters long, with a dark brown body and white hairs around it, and every few seconds a bug floats down from the trees and falls like snow on the surrounding bodywork and fitness equipment as the breeze blows.
A Mercedes benz parked under a tree was full of bugs, some of which crawled through the gaps in the engine cover. Not only did they squirm by the trees, but they were also densely packed with bugs and carcasses on the poles and walls of the courtyard, on the eaves, and at the entrances of the stairs.
The reporter noticed that the original white wall has been covered with black spots, and the bugs are constantly squirming upwards, and some bugs even climb to the window on the 2nd floor.
When the reporter took pictures of the scene, he suddenly heard a "pop" sound, only to see a caterpillar fall on the reporter, the reporter hurriedly used his hand to play with the insect, trying to fly the insect bullet, but dozens of tentacles of the insect were already hooked on the clothes, and the reporter had to pinch the insects and remove them from the clothes.
On the other five or six acacia trees in the courtyard, although the branches are luxuriant and not as tall as ailanthus trees, it can be seen that caterpillars are spreading to these trees, crawling on the trunks.
On the afternoon of the 13th, the reporter will see the situation to the Right North Avenue Community Neighborhood Committee to reflect, the staff Ms. Wang replied on the phone on the 14th, after receiving feedback from residents, she has urgently contacted the garden department to spray the disposal, and the preliminary judgment of the flooded insects on the tree is the American white moth larvae, which have occurred in many places nearby.
Mr. Chen, a staff member of the Beijing Municipal Bureau of Landscaping, said that this American white moth larvae belong to invasive alien species, and the insects are extremely fertile and eat leaves for a living.
"The appearance time of the American white moth larvae is generally in the summer and autumn, and the recent rain is large, which may accelerate the reproduction of the insect to some extent." Mr. Chen introduced that the method of eliminating the insect is also relatively simple, and it only needs to be fully medicated to kill it.
