In our childhood textbooks, we have all learned the stories of ladybugs, bees, praying mantis, dragonflies, etc.
to defend the crops, and now this story is truly interpreted in the cabbage (cabbage) field in Fanglong Village, Tengqiao Town, Lucheng District, Wenzhou.

.
This piece of cabbage field planted by the Wenzhou Academy of Agricultural Sciences has not been sprayed with pesticides since it was planted.
The growth of cabbage is as good as spraying pesticides
.
The reporter learned that this is mainly dependent on the insect helper that the Chinese Academy of Agricultural Sciences invites from the Institute of Entomology of Zhejiang University, which can kill aphids through the production of eggs, and use the method of "controlling insects with insects" to make cabbage.
Protect from pests in spring
.
For farmers, another advantage of "controlling insects with insects" is to help reduce the cost of pesticides
.
Generally, the cost of pesticides and labor is about 20 yuan/mu to 30 yuan/mu, which is much higher than the cost of putting natural enemy insects
.
Chen Xuexin, director of the Institute of Entomology of Zhejiang University, said that in general, vegetable fields must be sprayed at least 5-6 times a season to effectively reduce pests.
While reducing pests, beneficial insects have also been hit considerably, and the remaining drug resistance Pests are very likely to break out and become disasters
.
This situation can be avoided by using the method of "controlling insects with insects".
Generally, four natural enemy insects in the first quarter can replace the amount of pesticides in this quarter, which can kill the insects and restore the damaged ecosystem at the same time
.
In addition to the method of "controlling insects with insects", in recent years, our city has also adopted environmentally friendly technical measures such as ecological control, biological control and physical control to control crop diseases and insect pests, and establish green prevention and control demonstration areas
.
It is reported that last year, the city’s fruit and vegetable pesticide residues were qualitatively sampled, and the pass rate reached about 99%, reducing the amount of chemical pesticides by more than 200 tons
