Description

Technical Field

[0001] The utility model relates to the technical field of insect pest monitoring, in particular to an automatic monitoring and trapping device for insect pests such as cotton leafhoppers and whiteflies. Background Art

[0002] There are many types of crop pests with great impacts, and their scope and severity may cause significant losses to agricultural production. For example, cotton leafhoppers occur at a high density in Hunan and other regions. They mainly feed on the back of cotton leaves with adults and nymphs, causing the leaves to shrink to varying degrees, forming leaf shrinkage disease. In severely affected cotton fields, the leaves turn from red to black, and the entire cotton field looks like it is on fire, and finally withers and falls off. Moreover, compared with the past, the occurrence period of cotton leafhoppers has been significantly advanced, and in severe cases, cotton fields can cause total production. In addition to cotton, cotton leafhoppers also harm crops such as kapok, eggplant, beans, and tobacco. The adults and nymphs of Bemisia tabaci suck the juice of cotton leaves, causing yellow spots to appear on the front of the cotton leaves. In severe cases, the cotton plants weaken and even die, causing a large number of buds and bolls to fall off. The secreted honeydew can induce sooty mold and can also spread viral diseases. In 2022, Bemisia tabaci occurred in some cotton areas, and the phenomenon of "unkillable" appeared, which had a major impact on cotton production.

[0003] Pest monitoring is one of the most vigorously promoted plant protection work at present. It can timely feedback the pest situation, and timely and effectively prevent and control the occurrence of pests according to the specific pest situation, so as to minimize the losses caused by pests. The pest monitoring equipment in the prior art is usually a fixed camera, which monitors plants in a relatively wide range in a rough manner. The data obtained from the monitoring is not only difficult to process but also lacks accuracy, which affects the effect of pest prevention and control. The technology of trapping and killing pests with sticky insect color plates is a physical control technology that uses the attraction of pests to colors to trap and kill pests. However, in actual use, it will also trap and kill a large number of natural enemy insects, affecting or even destroying the ecological balance. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a crop pest automatic monitoring and trapping device with a reasonable structural design.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application. The parts not described in detail below shall be carried out according to conventional techniques in the art.

[0019] like Figure 1-3 As shown, the crop pest automatic monitoring and trapping device of the utility model includes a camera, a lifting rod, and a rain cover; wherein the lifting rod 1 is a conventional electric lifting rod in the prior art, a cross bar 2 is fixedly connected to the top of the electric lifting rod 1, and a height measuring sensor 3 is fixedly connected to the other end (called the free end) of the cross bar 2. The height measuring sensor 3 uses the infrared ranging principle to measure the height of the crop plant. A mounting groove is provided at the bottom of the cross bar 2, and a controller 4 is fixedly connected in the mounting groove. The height measuring sensor 3 is electrically connected to the input end of the controller 4, and the information (signal) detected by the height measuring sensor 3 is transmitted to the controller 4, which is analyzed and judged by the controller 4, and then the automatic lifting of the electric lifting rod 1 is controlled, so that the hanging height of the sticky insect color plate on the electric lifting rod 1 is always about 10 cm higher than the top of the plant. The controller 4 can use a single chip microcomputer commonly used in the prior art and capable of realizing the function of the present application. The signal line (data line) electrically connected to the controller 4 can be routed at the bottom or inside of the cross bar, and the side of the lifting rod, and fixed by a line card.

[0020] A rain shield 5 is hung or fixedly connected on the cross bar 2. The inner and outer sides of the rain shield 5 are printed with insect pest attracting color blocks 6 and natural enemy intimidation color blocks 7, wherein the insect pest attracting color blocks 6 are located on the inner or outer side of the rain shield 5 and occupy 50%-80% of the area of ​​the rain shield. The insect pest attracting color blocks 6 are formed by alternating distribution of red color blocks 6.1 and yellow color blocks 6.2 along the circumferential direction, each yellow color block 6.2 is in the shape of a water drop or a petal, each red color block 6.1 is located between two corresponding adjacent yellow color blocks, and the red color blocks and the yellow color blocks basically cover the corresponding sides of the rain shield, except for the black line and the eye spot on the edge of the rain shield. The experiment found that the alternating distribution of the red color blocks 6.1 and the yellow color blocks 6.2 as described above has a better attracting effect on cotton leafhoppers and whiteflies than using yellow alone, and red is a typical warning color, which has a certain warning effect on natural enemy insects. The natural enemy intimidation color block 7 is located at the edge of the rain shield 5 and occupies 20%-50% of the area of ​​the rain shield. The natural enemy intimidation color block 7 mainly plays the role of intimidating natural enemy insects such as cotton leafhoppers and whiteflies to prevent them from flying in and adhering to the sticky insect color plate. In practical applications, the natural enemy intimidation color block 7 is mainly composed of a plurality of eye spots 7.1 (or eye-shaped patterns) distributed on the corresponding positions of the corresponding sides of the rain shield 5 and a black line 7.2 printed on the edge line of the rain shield, wherein the eye spots 7.1 are located in the red color block 6.1 and close to the edge. The specific shape of the eye spots 7.1 is the same as the insect eye spots in nature in the prior art, such as each eye spot is a circular or nearly circular black color block (with a white bright spot in the middle), and then there is a bright ring of yellow, brown or yellowish white, etc., which is different from black, on the periphery of the black color block, and finally there is a black circle outside the bright ring.

[0021] A sticky insect color plate 8 (yellow color plates on the market or the same color block design as the rain cover) is hung on the top of the rain cover 5. A camera 9 is connected to the two sides of the sticky insect color plate 8 in the rain cover 5. Each camera 9 is installed at an elevation angle and is aimed at the corresponding side of the sticky insect color plate 8.
