Description

device for trapping insects

technical field

The invention relates to an insect catching tool for preventing and controlling agricultural pests, in particular to a high-efficiency insect attractant trapping device.

Background technique

Insect pests are one of the important problems restricting agricultural production, often causing large-scale crop production reduction or even failure, resulting in serious economic losses. With the progress of society and the widespread concern of humans on healthy food safety, pest control strategies are increasingly developing in the direction of pest management (SPM), ecological management (EPM), and sustainable management (SPM). In the process of agricultural production, new and pollution-free pest control technologies are gradually replacing traditional chemical control, and are playing an increasingly important role in integrated pest control.

Using artificially synthesized sex pheromone attractants to trap and kill insects is a new technology of pest control with high efficiency, non-toxicity and pollution-free. Insect sex pheromone is a compound that regulates the behavior of insects to attract males and females. It is sensitive and specific, with long-distance action and strong temptation. Using this technology can kill a large number of male insects, thereby reducing natural mating in the field, and achieving the effect of reducing the offspring of pests.

Sex lure trapping technology requires suitable traps as carriers. The traditional sex lure traps have good trapping effects with water basin type and sticky plate type, but they all have certain defects when used in production. For example, water basin traps need to add water every day in arid regions and hot seasons to achieve a better trapping effect, and water replenishment is a very heavy workload in actual work, which hinders the popularization of this control method. The glue on the sticky plate type trap loses its effect because it is easy to dry out and stick to the dust, so that the trapping effect is not ideal in hot areas and areas with large wind and sand such as near desert areas. Like this, because the defect of trap, make most farmers in many areas directly abandon this insecticide mode, cause letter lure trap technology to be difficult to popularize in field production. Therefore, making a time-saving, labor-saving, efficient, and simple trapping device with water replenishment effect, multiple hunting methods, is a strong demand for popularizing the technology of attractant pest control.

Contents of the invention

The purpose of the present invention is to provide a device for trapping insects, which solves the problems of rapid water evaporation, single trapping method, poor trapping effect, and inability to automatically replenish water in traditional lure traps in pest hunting.

The technical scheme of the present invention is as follows; a device for trapping insects, including a trap and a water supply device positioned above the trap, the trap is composed of a water basin and a float, water is housed in the water basin, and the float floats On the water surface in the water basin, a pheromone attractant source is placed on the float; the water replenishment device is a water tank, the upper part of the water tank is provided with a water replenishment port, and at least one water pipe is installed in the lower part, and the nozzle of the water pipe is inserted into the water basin below the surface of the water.

Preferably, at least two float fins are connected to opposite sides of the float, overflow holes are provided on the opening edge of the water basin, a sunshade is provided on the lower edge of the water tank, and a glue board is provided on the lower surface of the water tank The groove is provided with a hook along the lower edge of the water tank, and the trap is hung below the water tank by the hook, and the water tank is equipped with a hook for hanging the water tank.

Compared with the existing insect trap device, the present invention has the following characteristics:

1. The upper water tank can effectively reduce the contact surface area between water and air, reduce water evaporation, and effectively save water. Using the principle of atmospheric pressure, the upper water tank remains stable in a closed state after it is filled with water. Although there is a water pipe connected to the water surface in the lower basin, the water will not flow out, but when the water surface in the water basin is lower than the lower end of the water pipe, Then the water in the water tank will flow out automatically so as to achieve the purpose of replenishing water in the lower basin in time; the upper sunshade device can effectively reduce sunlight exposure and water evaporation; the lower water container has an isolating agent to separate the water from the air and reduce moisture of evaporation.

After testing, the product can be used in arid areas such as Shanxi after being filled with water. It can last for 10-15 days at a time before replenishing water, which greatly exceeds the replenishment interval of ordinary traps. Compared with ordinary traps that replenish water every day, it saves a lot of labor.

2. Multiple killing methods, attracting adult flying insects to gather in the cavity of the trapping device through sexual lures. When flying upwards, they are easily stuck by the upper adhesive board and cannot break free. When flying downwards or encountering obstacles, they are easy to fall into the water basin below. In the middle, it is absorbed by the adsorbent in the water and cannot break free. At the same time, the upper viscose board is affected by the evaporation of a small amount of water from the lower part, so it is not easy to lose its viscosity and prolong the service life of the viscose board, while the viscose board is under the sun visor, it will not be exposed to the sun, it is not easy to dry, and it saves the investment cost .

3. Automatic drainage: When there is heavy rainfall, there is an overflow hole on the edge of the opening of the lower basin to discharge excess water, and at the same time, the upper sunshade can prevent the glued board from being drenched by rain, ensuring the trapping effect of the trap.

4. Dynamic setting of the lure source: change the way of fixing the lure source on the upper part, so that the lure source drops with the water surface, and the distance from the water surface is within 1cm to achieve the best trapping effect. Moreover, through the blocking of the float fins, the float will not deviate to one side, and is always located in the center of the water basin.
