On the 30th, this newspaper reported the outbreak of street trees in some sections of the city. In the morning of the same day, the newspaper's official WeChat reporting platform has received a number of citizens who have reported that caterpillars appear in the street trees in many sections of Shahekou District and Ganjingzi District. Some of the sycamore leaves have begun to turn yellow, and some of the leaves have been eaten clean, leaving only the stems of the leaves. It is hoped that the garden department can carry out the killing work as soon as possible.
The caterpillar raided and nibbled away at the leaves of the big tree in a matter of days
"Some time ago, the trees were still lush, and it was only a few days, and they were almost eaten." In Xinyou Park near Dunhuang Road in Shahekou District, a large number of caterpillars appear in the street trees. Ms. Liu said that the park is surrounded by a circle of 400 pedestrian paths, planted with a large number of plane trees, poplar trees and so on. Because the trees in the park are planted for a long time and are leafy, it has always been a good place for residents to cool down and chat. In the past half a month, a large number of caterpillars have appeared on the trees. The leaves that remained only the stems had dried up and could no longer be shaded by hanging on the trees. Live caterpillars can also be found on dead leaves that fall to the ground. "Now walking here is walking carefully, one that fell on my arm yesterday, and it's still alive, and it scares me." Ms. Liu told reporters, "A few days ago, the big guys were still talking about it, there were caterpillars turning into white moths, everyone felt that their scalps were tingling every time they passed by, and the children were also very scared, and they didn't dare to play here." "
Ms. Yang, a citizen, lives on the 3rd floor of Building 137, Taishan Street, Shahekou District, and is adjacent to the street tree due to its low floor. Ms. Yang said she had been "fighting" the caterpillar at home for 4 days. Pesticides, alcohol, boiling water, Ms. Yang tried everything she could think of, but still to no avail. The windows of the home are still crawling with caterpillars. The large number of caterpillars makes Ms. Yang and her family miserable, and the first thing to do when she wakes up every morning is to know the caterpillars crawling all over the windows.
The second-generation American white moth appears in many parts of the city
During the interview, the reporter learned. In other sections of Shahekou District and parts of Ganjingzi District, there are also a large number of second-generation American white moths, which citizens call "caterpillars". Most of the affected trees are leafy trees such as plane trees. At present, it has spread in many communities in our city, and even the residents' flowers and plants have not been spared. Ms. Li, a resident, told reporters that the flowers and grass in her small courtyard have been eaten to the point that there is not a single leaf left, "Every once in a while, you have to come out to sweep the insects, and a bug can eat several leaves a night." Ms. Li said she was very distressed. On Fengtai Street in Shahekou District, even residents with higher floors have their windows closed. No one dares to stay in the pavilions and communities that can be used for the public to shade and cool off.
