Description
Technical Field
The invention belongs to the technical field of biological control, and particularly relates to a releasing device for beneficial insects in an insect control technology.
Background
For pest control, humans undergo a lengthy process. Meanwhile, the use of pesticides provides great help for agricultural production, and causes serious damage to ecology and environment.
At present, the agricultural development in China is facing a severe test, and the problems of ecological damage, environmental pollution and food safety caused by the use of pesticides and the like are continuously exposed. In addition, the side effects of chemical pesticides are gradually appearing, and many domestic conventional drugs face the problem of serious drug resistance.
in the light of such background, under the current situation, under the introduction of the ecological civilization development concept, a biological insect control industry for preventing and controlling insect pests, namely 'green technology' for preventing and controlling insect pests 'by using insect pests', which reduces or even does not use pesticide, is met with development opportunity.
All things in the world have natural enemies, and the 'control of insects by insects' is a method for killing agricultural and forestry pests by utilizing the natural enemies of parasitic and predatory insects, and is an important content in the biological control technology. The natural enemy resources of insects in China are quite rich, and the ancient China records that the insect pests of oranges and tangerines are controlled by utilizing the predatory nature of the Indian Muntjac ants. The natural enemy insects do not have ecological risks. The insect population is a component in nature, the insect population has strong special feeding property, and after a large number of pests are eliminated, the population quantity returns to a normal state due to the existence of food shortage and natural enemies, so that negative influence on the ecological environment is avoided. At present, in many places throughout the country, a treatment mode of 'controlling insects by insects' is being developed and applied, but when beneficial insects are released, a relatively original manual release mode is still adopted, the time consumption is long, the workload is large, and when the beneficial insects are released by an unmanned aerial vehicle, suspension mixed eggs are mostly adopted for spraying, so that natural enemies can easily prey on the beneficial insects.
The inventor finds that the insect control technology at least has the following technical problems in the practical use process:
1. The manual spreading is difficult to realize in the case of large-area prevention and control, and wastes time and labor.
2. When the rain water is spread, the pathological changes and drowning of eggs and larvae can be caused, and the survival rate is greatly influenced by weather reasons.
3. Eggs and larvae have no self-protective ability basically and are easy to be prey by natural enemies.
