Description

Technical Field

[0001] The invention relates to the technical field of ecological prevention and control, and in particular to a device for preventing and controlling golden apple snails and a use method thereof. Background Art

[0002] The golden apple snail is native to the Amazon River Basin in South America. Due to its strong adaptability, it has been artificially introduced to many countries and regions. In China, the golden apple snail is mainly distributed in most waters in the south. As an alien species, the golden apple snail lacks effective natural enemies in the new ecological environment. Their large-scale reproduction will change the structure and function of the aquatic ecosystem. The golden apple snail mainly inhabits shallow low-lying areas such as ditches, fish ponds, and farmlands, or attaches to the stems and leaves of aquatic plants. It will eat a large number of seedlings of crops such as rice, causing the seedlings to break and die, seriously affecting the planting and yield of rice.

[0003] At present, common control methods for golden apple snails include physical control, biological control, chemical control, etc. However, although physical control is harmless to the environment, it is time-consuming and labor-intensive; although chemical control methods are effective, they will affect the ecological environment, disrupt the ecological balance, and the problem of drug residues cannot be ignored; biological control is labor-saving and has few side effects, but it is slow to take effect and difficult to control.

[0004] Studies have shown that the incubation period of golden apple snail eggs is about 9 to 13 days. They need to be exposed to the air to hatch normally. Snail eggs immersed in water cannot hatch. The hatching rate of snail eggs immersed in water for 4 days is reduced to about 50% (92% for non-immersed eggs), and the hatching rate drops to less than 1% after 7 days of immersion. At the same time, snail eggs entering the water will significantly increase the chances of various predators eating snail eggs, greatly reducing the chance of snail eggs hatching. Practice has shown that eliminating golden apple snail eggs is an effective way to reduce its population. However, in the actual prevention and control process, due to the long coastline of natural water bodies, manual removal of snail eggs is often difficult to effectively implement because it requires a lot of manpower. Using artificial attachments such as wooden strips and bamboo strips to induce spawning is an effective prevention and control method, but it requires a lot of manpower to regularly clean the snail eggs attached to them, which is costly and inefficient.
