According to beijing citizens in recent days, many green meat worms appear to be seen in the streets more than in previous years. Journalists were informed by the beijing park greening resource protection centre that the larvae, commonly referred to as “scattered ghost”, is currently in larvae as reflected by netizens. The city-wide response has been put in place and, according to the current monitoring, the extent of its occurrence is comparable to that of previous years。
Beijing's master biocontrol tool to achieve “insect infestation”
According to yuan fei, chief of the integrated prevention section of the greening resources protection centre of beijing city, the larvae, commonly known as the “scattered ghost”, is known for its constant sprouting, usually with the highest number of trees, such as the larvae and the dragon claws. The larvae larvae, which often crawl into trees and eat leaves, sometimes eat all the leaves。
In may each year, the larvae are in larvae and some parts of the country are endangered, but the overall number in beijing is small. “the vermin is a common pest in beijing, and there will be a small number of disturbances in local areas, such as the leaching of their spitting cords on trees or on the ground, known as caterpillars, which can make people sick or scared. But there were no serious pests in large areas." yuan fei said。
Beijing has also taken appropriate preventive measures. For example, the release of its natural enemy red-eyed bee during the larvae period, where the bee eats the eggs of the larvae, and the spraying of non-hazardous drugs in its relatively large larvae areas. At the end of may and the beginning of june, the larvae will fall out of the tree, drilled into the shallow earth or melted under the rock, which, after about a dozen days, becomes a butterfly-like insect. Insects are luminescence, so they are usually booby-trapped with insecticidal lamps。
According to yuan fei, at present the level of surveillance at municipal and district monitoring points is normal, and there is no sudden increase in any district. “insects are also part of the biological chain, and we dominate biological control tools, such as insect treatment, to achieve ecological balance through natural regulation, and to achieve `insect infestation'.”
This was preceded by reports from citizens that there was a lot of grass in the trees in the district. Yuan fei said that the number of grasshoppers had not increased this year compared to previous years. Controls are usually carried out using adhesive tape to “penetrate” trees, and when the insect climbs to the position of the adhesive tape, it gathers near the tape because it is slippery and difficult to cross, which allows for centralized clean-up。
She stated that citizens could contact the property and the streets outside the community if they found more insects in small areas. The forest protection sector in the districts will also strengthen monitoring and technical support。
Why did the pests grow the country? Expert: the tree canopy is so adaptable
Some netizens want to know why beijing is growing so many bugs in the summer
Zhao shiwei, a professor at the beijing school of greening sciences, stated that the country's qin is more adapted to the environment in the north and is an excellent country-based species. “the trees, such as pine trees, oil and white-covered pines, grow well in the mountains, but not in the cities because they fear heat. Elm trees are particularly adaptable to the urban environment, for example in the heat island effect, air pollution, etc., and are more easily grown.”
Moreover, the country's canopy is very large and its shades are particularly thick and can provide a cooler environment for pedestrians during the inflammation summer. At the same time, the fallow tree of the country's land leaves fell off in winter, allowing people to bathe in the sun. The branches of the country are standing and well-formed, and among the ancient trees of beijing, the country is an important tree。
Zhao shiwei stated that a tree species cannot have only its virtues, and that it is one of the shortcomings of the nation's herbs, but it is not difficult to combat it by means of means. “there are insects in nature, there are food in birds, and worms are part of the biological chain.” he believed that, within a limited range, people should live in peace with various organisms, including insects。
“also, there were those who did not like the aphids because they had the alias `handing ghosts' and felt unlucky and preferred insects like `gold turtles'. In fact, the name or aliases of insects are human and have no meaning, which requires a change of mind.” zhao shiwei said。
