Description

Device and method for attracting and controlling African snails Technical Field The invention relates to the technical field of agricultural pest control, in particular to a device for attracting and controlling African snails and an application method thereof. Background The African snail is a serious agricultural invasion pest worldwide, and has wide feeding spectrum, strong reproductive capacity and strong environmental adaptability, and causes wide and serious harm to vegetables, melons and fruits, grain crops, economic forests and the like. The monitoring and control of the disease is extremely difficult due to its diurnal emission, the habit of happy yin and wet, and the powerful reproductive and viability. At present, the control of the African snails mainly depends on comprehensive measures such as physical control, chemical control, biological control and the like. Physical control such as manual capture has low efficiency and high labor cost, chemical control such as molluscicide spraying has the problems of quick response but pesticide residue, environmental pollution, killing of non-target beneficial organisms and the like, and biological control such as natural enemies has unstable effect and is difficult to apply on a large scale. In recent years, some control technologies based on trapping devices have emerged. For example, CN113317304a discloses a snail trapping box in africa, which adopts a metal box body and comb-shaped rack structure, and is matched with dry granular poison baits made of stir-fried wheat bran, shikim grass, henbane and the like for trapping and killing. The technology realizes the trapping function to a certain extent, but the trapping mode is single, the trapping effect is obviously reduced under the high-temperature drying environment mainly depending on the smell of the bait, and the palatability of the dried bait is poor, so that the feeding rate and the prevention and treatment effect are affected. CO2024017931U1 then discloses a folding physical trap, realizes trapping of snails through the combination of a geometric structure and an attracting pad, lacks effective initiative attraction and environment regulation and control capability, has limited trapping efficiency, can not be directly killed after trapping, needs manual secondary treatment, and increases operation cost and health risks. In the process of implementing the present invention, the inventor finds that at least one of the following technical problems exists in the prior art: a) The existing trapping device has single trapping means, depends on natural smell of bait or simple attractant, lacks active regulation and control on environmental factors (such as humidity), and causes rapid reduction of trapping efficiency under adverse environmental conditions such as high temperature, drought and the like; b) The escape-proof structure (such as a comb-shaped rack and an inverted inclined plane) in the prior art mainly aims at snails entering the device, lacks an active and long-acting attraction mechanism for long-distance snails, and has limited action radius; c) The existing poison baits are mostly prepared into dry granules, and the eating habit of the African snails for wetting and softening foods is inconsistent, so that the eating rate is low, and the final control effect is affected; d) The prior art mostly combines the functions of attracting and poisoning simply, lacks systematic and multi-level synergistic effect design, has isolated functions of all parts, and cannot realize progressive Gao Xiaoyou control of environment simulation, odor guidance and food intake control. Disclosure of Invention In view of the above, the present invention aims to provide a systematic device and method capable of actively creating a suitable microenvironment, realizing long-acting long-distance attraction, and having excellent palatability, so as to overcome the defects of the prior art and realize more efficient, environment-friendly and stable control of african snails. The inventor has continuously innovated through long-term exploration and trial and repeated experiments and efforts, and in order to solve the technical problems, the technical scheme provided by the invention is that a device for attracting and controlling african big snails is provided, which comprises: the trapping shed is internally constructed to simulate a cool and moist microenvironment; the trapping paste is arranged in the trapping shed and is used for continuously releasing volatile trapping substances; a plant source control agent which is arranged above or on the periphery of the trapping paste; the trapping shed, the trapping paste and the plant source control agent are arranged in a combined mode in space so as to cooperatively realize that the african snails are induced to enter the device through environmental simulation and odor induction, and then the feeding behavior of the african snails is interfered through the plant source
