Description

Technical Field

[0001] The utility model belongs to the technical field of pest capture, and particularly relates to a live pest trap. Background Art

[0002] The living environments of field pests and laboratory pests are different, and there are significant differences in their biological characteristics and environmental adaptabilities. Among them, laboratory pests are sensitive individuals with low drug sensitivity, poor drug resistance and adaptability. Laboratory pests can provide support for the initial development and testing of new pesticides or biological control methods. In the verification test stage of new pesticides or biological control methods, it is necessary to conduct verification tests through field pests with better adaptability and drug resistance, which helps to develop new pesticides or biological control methods that better meet the actual agricultural production needs and improve the control effect. Field pests, such as flea beetles, are important crop pests. The adults eat leaves and the larvae eat roots. They can fly and jump well and have high resistance, which brings great difficulties to control. Since flea beetles can fly and jump well, they are easily frightened and flee in all directions. After being frightened, they will jump off the leaves and turn over and feign death briefly after landing, making it difficult to capture them. Existing pest traps use a simple cone net structure. When capturing live pests, the pests are easily escaped along the net opening, affecting the capture efficiency of live pests.

[0003] In addition, the length of the net handle of most pest traps cannot be adjusted. There are significant differences in the heights of pest-catching personnel and field plants. When pest-catching personnel use such pest traps, they have to bend down or stand on tiptoe to hold the trap in a suitable position. When the plant height is relatively low, they have to lie on the ground during capture to align the net opening of the trap with the plant leaves to achieve the pest capture action. However, live pests are easily frightened and flee in all directions, and it is extremely easy for the pest-catching personnel to cause the live pests to be frightened and escape when adjusting their movements, affecting the capture of live pests.

[0004] Chinese Patent with the authorization announcement number CN217826469U discloses a pest-catching device for facilitating the collection of live insects in the field, including a net rod, a net bag and a collector. The net rod is connected to the net bag. The net bag is provided with an inlet, and the side of the net bag away from the inlet is provided with an outlet. The collector is a cavity with an opening, and the opening of the collector is detachably connected to the outlet of the net bag. The pest-catching device for facilitating the collection of live insects in the field provided by this utility model can confine the insects in the collector when the insects are captured, and then the collector can be removed; there is no need to take out the insects from the net bag again and place them in the collector, avoiding the situation of insect escape during the transfer process. When capturing insects in the field, the insects are easily escaped from the inlet of the net bag, affecting the capture efficiency of live pests, and this utility model cannot adjust the extension length of the net rod as needed, making it difficult to meet the need for capturing pests on plants at different heights. Summary of the Utility Model

[0005] To solve the above problems, a live pest trap capable of capturing pests in the field is provided.

[0020] (2) The setting of the elastic net ring facilitates putting the conical net bag on the whole plant or plant leaves when catching pests. After the pests are frightened and bounce or fly up, they fall into the conical net belt, realizing an effective catching action for live pests; the end gap of the elastic net plate inclined towards the inside of the conical net bag is in clearance fit with the net cloth to form a narrow channel at the end. After the frightened live pests enter the conical net bag along this channel, this channel can prevent the live pests from returning, enhancing the catching efficiency of live pests; both the elastic net ring and the elastic net plate are made of elastic materials, which can effectively reduce the harm to live pests and improve the integrity and survival probability of the caught live pests.
