Raise a lot of "insect stars", she is a "plant doctor" in the city

The Yangtze River Daily Da Wuhan client June 29. When the old people raised the "cats" and "Wang Xingren", Wang Zhihua in the post -85s raised tens of thousands of "Star Stars".

The reporter asked: "Girls raising insects, wouldn't he get a cricket?" She thought about it seriously and replied: "It seems that there is really no. There are more than 10 million types of insects, which are the largest number of animal groups on the planet. When you really like it, you won't be afraid, you will find that the world of insects is really wonderful! "She is the" plant doctor "in the city

More than a hundred types of insects have been raised in 9 years

Wang Zhihua is an engineer of the Institute of Botanical Protection of the Institute of Garden Sciences of Wuhan City. It is mainly engaged in research on the research of garden plant harmful biological related topics, predictions for pest pests, prevention and treatment guidance, and science education.

On the 27th, the reporter came to the plant protection office laboratory, as if entering the insect world. Wang Zhihua was experimenting on the operation platform, and there were all kinds of bugs in the bottles and cans on hand.

The reporter pointed to a bottle of a densely pair of software insects, saying that he was going goosebumps. Wang Zhihua smiled and quickly "rehabilitated" for her pets: "This is a large waxy, its feed is red dates, honey, milk powder, very clean."

As the reporter visited, she was like a few treasures: "The green is a little praying mantis, a kind of natural enemy predating, and can prey many pests; these small black flyworms are mung bean elephants, a very good host ..."

Why do you have so many bugs? Wang Zhihua explained that doing plant protection work is like a "plant doctor" in the city. On the one hand, they will raise various pests, observe the time and living habits of plant diseased and insect pests, understand the "enemy", and apply the right medicine; on the other hand, It will also raise various natural enemies or hosts (natural enemies are insects that can eliminate pests, and hosts can be understood as "food" of other insects), so as to explore the biological prevention and control technology such as "governing insects".

As of now, she and her colleagues have raised more than a hundred kinds of insects, and the number needs to be used as a counting unit.

In addition to raising insects and experiments in the laboratory, Wang Zhihua and colleagues often risked in the cold heat and went to the street green space or urban park to conduct a survey of garden plant diseases and insect pests. Essence

Carefully support feed, build villas

Raising insects is like "raising children"

Wang Zhihua raised the most is the swollen leg bee and flower velvet to send armor. They are natural enemies of the heavens. Tiande is a common dried pest in Wuhan, which is more harmful. Its larvae eat the curved tract in the trunk, which seriously affects the growth of the trees. A large amount of feces from the cavity also affect the urban ecological landscape.

Since 2013, the Academy of Park Sciences has begun to explore the green prevention and control of Tiandiu. In that year, Wang Zhihua, who had just entered the unit, provoked the burden of establishing a Tianyano enemy artificial breeding system.

The establishment of an artificial breeding system is quite cumbersome. In Wang Zhihua's words, it is like raising thousands of "insect children". What do they eat, where they live, is cold or warm, or even "family members", each detail requires a lot of time and patience Explore.

The breeding of the flower velvet is very difficult. Its larvae and adult form are different. The first problem that Wang Zhihua encountered is to find the right food for them.

Through repeated tests, Wang Zhihua found that the pupae of the barley insects can ensure the nutritional intake of the flower velvet larvae, so that it can be smoothly turned into a pupae and then into a adult. "But this means that in order to raise a flower velvet larvae, I have to raise a big wheat insect." Wang Zhihua said that raising a big wheat worm is not easy, and the individual will kill each other You need to prepare a "single room" for each worm.

Foods with flower velvet adults are used for artificial formula feed, including yellow powder pink powder, barley pink powder, amino acids, trace elements, glycerin and other ingredients. This combination is screened from 4 sets of feed. Through comparative tests, this group of feed fed flower velvet nails have the longest survival and the most egg yield.

Wang Zhihua also brought a transparent small box to tell reporters that this is a double -layer villa designed for the flower velvet to make them live and breed more comfortably. There are many small holes around the box to ensure ventilation and breathable. The upper layer is a living area with food plates, water sources, spawning cards, etc. The lower layer is "toilet". The excrement will fall through the interval between the middle. "This inspiration comes from the cage of the kitten puppy. The lower level is a drawer design that can be cleaned regularly, which is very convenient."

In addition to food and houses, she also studied the best temperature and humidity of flower velvet life, and under what temperature, adults' eggs can not be hatched and can be stored for a long time. Large -scale promotion and application

After several years of research, Wang Zhihua and his colleagues overcome various difficulties together, and finally explored the heavenly enemy breeding technical system suitable for Wuhan, and greatly increased the survival rate and egg yield of natural enemy flower velvet, swollen leg bees, and the amount of egg yielding. And two patents.

According to Wang Zhihua, one of the two invention patents is a flower velvet -to -nail breeding box, and the other is to release the card, like a white "small pocket", which is a device used to release natural enemies. With this set of Tianniu natural enemies breeding technology system, the swollen leg bees and flower velvet sending armor successfully invested large -scale reproduction. The biological prevention and control of Tianniu has also officially launched in Wuhan. Since 2018, the average annual number of natural enemy promotion has reached 20 The remaining tube. At present, 11 parks and 180 roads in the city have been applied, and tens of thousands of big trees have been protected. If the citizens of Wuhan see a release card hanging on the big tree, this shows that the tree is stationed on the tree.

"Biological prevention can greatly reduce the amount of pesticides in the streets or parks, safe and environmental protection, and also play a very important role in maintaining ecological safety and balance." Wang Zhihua introduced, "but it also has defects, that is, the effect cycle is relatively slow."

So since 2019, Wang Zhihua has begun to study continuing the topic: "Research and Demonstration of Tianshi Green Prevention and Control Technology System". According to the different phases of Tiandon larvae, adults, eggs, and pupae, comprehensive prevention and control measures combining biological control, physical control and necessary chemical prevention and control, have created an anniversary prevention and control technology system. She is not afraid of the "female man" of the worm

Working with insects all day, Wang Zhihua formed some "occupational diseases". When others are enjoying flowers, it is the flowers that attract Wang Zhihua. When she walked on the road with her family, she always liked to catch it and take it back to raise it.

"Fortunately, both husbands and daughters are not scared by my" special hobby '. "Wang Zhihua said embarrassedly that in the eyes of her husband, she was a" female man "who was not afraid of bugs, but her husband also supported her work. Sometimes experiments worked overtime overtime He will also help do experiments together.

Under the influence of Wang Zhihua, her four -year -old daughter also grew into a happy girl who loves nature. "She often says that I am like Dr. Gao Gao in the cartoon" Cute Qiaohu Island ". She is an omnipotent insect scholar. She always grabs a bug or picks a little flower for me as a gift."

In addition to the "female man" and "Dr. Gao Gao", Wang Zhihua also has another identity -the children of the children like. In addition to busy scientific research, Wang Zhihua actively participated in various popular science education activities organized by the unit. Her science science course "Entering Insect Micro World", "Insect Summer Camp", "Interesting Insect Mouth" and other children are loved by children. The "Secret of the Start Kingdom" she lectured won the excellent award in the Wuhan Popular Science Explanation Contest in 2021. The book "The Insects around" was written by Wuhan's outstanding popular science works.

She said that every time I taught children to know insects, she would have a sense of accomplishment. "When they caught a butterfly or dragonfly and caught a fireflies or elephant armor, I was particularly joyful and carefully observed them, and I also felt particularly happy and happy. I wanted to share all the knowledge I knew with them. . "(Changjiang Daily reporter Yang Xiaoyu correspondent Wu Xiaozhao Yinfei)
