The reporter from the Yangtze River Daily saw at the scene that the ladylike ladybug was slightly lighter than the ordinary ladybugs. It was packed in a transparent small round box with a pore. Crazy. The garden conservation staff walked in front of a Lagerstroemia tree, tied the transparent small round box to the trunk with plastic straps, and then gently opened the box cover. The ladybugs seemed to feel the open space and slowly crawled towards the outside of the box. Some quickly climbed on the trunk and searched towards the target of aphids.

Feng Wei, person in charge of Wuhan Garden Ecological Group, introduced that aphids and insect pests have occurred all year round. The outbreak period from March to May each year and the most harmful hazards in September and October each year, not only eroded the trees, but also caused leaves' loss. Growth, its excrement will also cause "oil dripping" phenomenon, affecting the aesthetics of the road.

Before the outbreak of aphids this spring, the company and the Hanyang District Garden Bureau adopted the "customized" solution to treat the aphids with a lot of aphids and achieved good results. In order to maintain the effect of governance, the company started to prepare for governance before the autumn explosion in advance, and obtained objective data by release of different -color ladybugs for the preparation of subsequent governance plans.

Wang Lingling, a staff member of the science and technology maintenance department cultivated by the specialty of ladybugs, told reporters that the single -colored ladybug adult adults can eat hundreds of aphids in a single day. The "combat power" is amazing and is a "good helper" for aphids.

On -site staff Wu Weihua said that after the release of the different -color ladybug, the observation frequency of the road will be increased to understand the governance effect. He pointed at a blazer full of black dots. "This is the leaves after chemical prevention. The worms are gone, and the tender leaves are almost eroded." On the other leaf, he saw that aphid was crawling. He planned to separate every separate separation of aphids. Let's take a few days to see if the aphids on this road have decreased significantly.

The reporter learned that "biological control" has been widely used in the treatment of pedestrian pests in the sidewalk trees in recent years. It has released the "natural enemies" of pests such as flower velvet, swollen leg bee, and heterosexual ladybugs, which has become an important means to assist conventional governance.

According to Feng Wei, in view of different governance methods for different tree species, the 60 road aisle trees in Hanyang District in the first half of the year did not have obvious pests and pests, creating a good urban green landscape effect. The garden department of this area plans to gradually increase biological control and treatment for important roads and residents' travel frequency in the region, and be the basis for the prevention and treatment of pests and insect pests in the second half of the year and even the coming year.
