What are the main biological control technologies?
Biological control techniques mainly include the following categories: 1. ** Using Natural Enemies to Control **: - ** Predatory creatures **: such as lacewings, ladybugs, walking bugs, chelae, amblusae, spiders, frogs, toads, mosquito-eating fish, spearfish, and many insect-eating beneficial birds. - [Parasitic Creatures: Parasitic wasps, parasitic flies, etc.] - ** Pathogenic microorganisms **: For example, B. thuijngensis, Beauveria bassiana, etc. In China, the use of the red ladybug to control the orange blowing scale, the use of Beauveria bassiana to control the soybean pod borer and corn borer, the use of the golden wasp to control the overwinter pink bollworm, and the use of the red wasp to control the cane borer were all successful cases. 2. ** Resistance-resistant crops **: Breeding resistant crop varieties to control pests and diseases. The resistance of crops to insects is expressed in tolerance, antimatter, and no preference. For example, breeding potato varieties that were resistant to potato late plague, sugar cane varieties that were resistant to mosaic disease, linen varieties that were resistant to fusaria wilt, and wheat varieties that were resistant to wheat stem flies. 3. ** Farming Control **: Changing the agricultural environment to reduce the occurrence of pests. 4. ** Insect control **: Collect or cultivate a large number of harmful insects, use gamma-rays or chemical sterilants to make them infertile, and then release them to mate with wild pests, causing their offspring to lose their reproductive ability. 5. ** Genetic Control **: By changing the genetic composition of harmful insects, the vitality of their offspring will be reduced, the fertility will be weakened, or there will be genetic infertility. 6. ** Use biological hormones or other metabolism products to control: Use some biological hormones or other metabolism products to make certain harmful insects lose their reproductive ability. For example, using pheromones to confuse insects so that they could not find a mate and could not reproduce smoothly; using the preparation of the wood mold to control plant damping-off, root rot, and root southern silk disease; using the radioactive soil bacteria K84 to control plant root cancer, etc. Read more exciting novels for free
Biological Control
Biological control can reduce the population density of harmful organisms such as weeds and pests. It uses the relationship between biological species to suppress one or another type of organism. It has little environmental pollution, can effectively protect natural enemies, play a role in continuous disaster prevention, low cost, safety to humans and animals, pests are not easy to produce drug resistance, reduce the amount of chemical pesticide, save energy and other prevention and control effects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the main measures for biological control?
Biological Control Information 2019
In 2019, there were many kinds of vegetable pests in the protected land. The main pests that occurred all year round were whiteflies, thrips, harmful mites, aphids and other piercing-sucking pests. The generations overlapped, the number of insects was large, the resistance was high, and the harm was serious. Occasionally, there were diamondback moths, cotton bollworms, Spodoptera exigue, Prodenia litura and other Lepidoterous pests. The cultivation environment of protected land was closed, and it was difficult for chemical pesticide to degrade and cause serious pollution. Biological control technology was an effective way to replace the use of chemical pesticide, ensure the quality and safety of vegetables, and promote green plant protection. The prevention and control goal of that year was to control and dispose more than 95% of the important pests in the protected vegetables, control more than 80% of the overall pest control effect, control the damage loss rate within 10%, and reduce the use of chemical pesticide by more than 50% compared with conventional control methods to ensure the safety of vegetable production and products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Biological control perspective
Why do biological control?
The main reasons for doing biological control were as follows: 1. The biggest advantage of biological control was that it did not pollute the environment, which was incomparable to non-biological pest control methods such as pesticides. 2. Dealing with pests: Under certain conditions, pests can cause harm to human life, production, and even survival. For example, pests and rats are a serious threat in the process of planting, breeding, processing, storage, and transportation. The impact of pests in industrial processing can cause huge economic losses. Biological control can reduce the population density of harmful organisms such as weeds and pests. 3. Use of biological relationships: Biological control uses the relationship between biological species to suppress one or another type of organism. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
List of Biological Control Scholars

What are the names of the drugs for biological control?
Biological control drugs have the following names: 1. ** Antibiotic Fungicide for Agriculture **: Nong Kang 120 (Pyrimidine Nucloside Antibiotic), Tetracycins (Wuningmycins), Polyoxin (Polyoxin), Kasugamycins (Kasugamycins), Zhongsheng Mycins (Zhongsheng Mycins or Nong Kang 751), Jinggangmycins (Validomycins), Ningnanmycins (Junkeduke), Wuyimycins (Astemicins or Wuyimycins), etc. 2. ** Microbiological Pesticide **: - ** Fungicide **: B. subtils, B. licheniformis, P. fluorescence, B. cereus, T. chrysoides, B. amyloliquefacient, etc. - ** Insect pesticide **: B. thuenziengiae, Helicoverpa armigera, Spodoptera californica, Spodoptera litura, Armyworm nuclear polyhedrosis virus, diamondback moth virus, grassland caterpillar nuclear polyhedrosis virus, tea caterpillar nuclear polyhedrosis virus, cabbage moth nuclear polyhedrosis virus, short stable bacteria, spore bacteria, cockroach virus, etc. 3. ** Other biological control drugs **: Beauveria bassiana, Yi Zhida (2% lentinan water solution), etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is the use of physical information a biological control
Based on context alone Biological control was a method of using one organism to deal with another organism. It mainly included using insects to control insects, birds to control insects, and bacteria to control insects. The use of physical information did not belong to biological control. Physical information referred to the light, sound, temperature, humidity, magnetic force, and other information transmitted through physical processes in the ecological system. For example, the vibration frequency of the spider web was a kind of physical information for spiders. This was different from the concept of biological control involving the use of biological relationships to control. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
