(Reporter Zhang Shuling) At noon today, the staff of Zhengyang Beili Community in Fengtai Street, Fengtai District nailed 30 eggs of Zhou's biting wasp on the thick paulownia trunk in the community. A week later, each bee egg will fly out of 5000 bees, unilaterally killing the good white moth in the community.

"You see, some leaves were eaten by white moths." Ms. Sun, a community neighborhood committee, said that white moths were found in the community the next summer, so black lights were hung in the community for monitoring at the beginning of this year, but the white moths still had a tendency to spread, and the effect was not good after taking the medicine twice.

"Using biotechnology such as Zhou's biting wasps can reduce the cost by more than 30%, and it is fashionable jewelry without purification and toxic reaction." Sun Xiguang of Fengtai Street Urban Management Division is responsible for this work. He said: "One egg can hatch 5000 wasps. According to the interval and accumulation, people are releasing 900 eggs in 24 communities in the street. In a few days, 4.5 million wasps will show their magical powers in the community and kill the white moth unilaterally. "

Many officials look around the small cocoon with purple-black pupa head to see rare things and jewelry portals. "I haven't seen a white moth killed like that. Those little bees won't sting themselves after flying out, will they? " Grandma Wang's concern caused a burst of laughter.
