Xinwang October 25 (reporter Sun Qian) on the ground, on the trunk, in the grass nest, on the wall, a white-haired insect crawled around and nibbled on the leaves, looking numb... Ms. Wang, who lives near Shuyuan Road in Licang District, said that on her way home in recent days, every time she passed under the Plane Tree in France, she wanted to hold an umbrella when she saw dense insects. Xinwang (0532-80889431) learned from Qingdao Licang Landscaping Engineering Co., Ltd. that this insect is the larvae of the American white moth, due to the fact that there is more rain in Qingdao this year, the air is humid, and the killing effect is not good, resulting in a wide distribution, not only appearing in Shuyuan Road in Licang District, where Ms. Wang is located, but also in Feixian Road, Signal Hill Road, etc. in Shinan District. The staff of Qingdao Shinan District Urban Greening Engineering Corporation told Xinwang that it is currently going all out to eliminate the killing, and after the killing, it will not recur this year.
Ms. Wang, a citizen who lives near Shuyuan Road in Licang District, said that in recent days, she found that the surrounding French plane trees were covered with brown, white hair, and two or three centimeters long bugs, "Just these few days, bugs are all over the place, often falling from trees, sometimes falling to pedestrians, my daughter does not dare to pass under the trees, too scary." Ms. Wang worries that once the bugs fall on passers-by, they will have a negative impact on pedestrians, "and I don't know if they are stinging or toxic, which makes the residents in our neighborhood uneasy." ”

Xinwang learned from Qingdao Licang Landscaping Engineering Co., Ltd. that the small insects referred to by Ms. Wang belong to the American white moth larvae, which is a kind of insect that adsorbs on the leaves and likes to eat leaves. After being sprayed by professionals, the American white moth larvae will die in about half an hour and fall from the tree, at this time if there is a pedestrian passing by, the bug has a certain chance of falling on passers-by.
Xinwang learned from Baidu Encyclopedia that the American white moth larvae are divided into three generations, of which the first generation of larvae appears in early May to mid-June, the second generation of larvae appears in early July to early August, and the third generation of larvae appears in mid-August to late September. The larvae are extremely resistant to hunger, and the mature larvae will not die even if they do not feed for 15 days.
According to Baidu Encyclopedia, the American white moth is native to North America, mainly distributed in the United States and southern Canada, its ecological distribution range is between 19 ° -55N °, its morphological characteristics are divided into adults, eggs, larvae, pupae, the American white moth has been included in the list of the first 16 invasive alien species in China by the State Environmental Protection Administration.
"Normally this bug appears in early August, but I don't understand why this happens in October." The staff member said that at present, the American white moth larvae on Shuyuan Road in Licang District have been eliminated, "In the process of killing, we have found that the larvae that caused the flood this time may be the second generation of the American white moth, and the reason for the flood may be caused by the recent rain in Qingdao and the humid environment." This insect not only feeds on French plane trees, but also on cherry blossoms, cypresses, locust trees and other tree species. ”
In addition, Xinwang learned from the staff of Qingdao Shinan District Urban Greening Engineering Corporation that due to the heavy rain and humidity in Qingdao this year, this weather will affect the spraying operation of the agent, "for example, after spraying, the forest is washed away by the rain, so that the drug will also be washed away, resulting in poor killing effect." The staff told the letter network that this year, the American white moth larvae not only appeared in Fei County Road, Signal Mountain Road, even around the Bada Lake and BadaGuan, "but please rest assured that the American white moth larvae will not sting people, there is no toxicity, we are going all out to kill, the current Fei County Road and Signal Mountain Road have completed the elimination, after the killing, this year will not recur." ”
Xinwang contacted the staff of Qingdao Forestry and Garden Bureau, the staff said that the current white moth has reached the "down tree" season, this time the public feedback is more concentrated, the relevant departments of the territory have made professional treatment for this problem, the staff said that every year will take control measures for the white moth problem.
