Technical Field

[0001] This utility model relates to an observation device for the aggregation behavior of tiny insects, belonging to the field of plant protection technology. Background Technology

[0002] Using attractants to control pests is an important aspect of plant protection. However, evaluating the attraction and repulsion of tiny insects to attractants under field conditions is usually difficult and often requires preliminary testing in the laboratory. Utility Model Content

It has a simple structure, reasonable design, and is easy to operate, allowing for a clear and intuitive observation of the effects of attractant substances on insects.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is an observation device for the aggregation behavior of tiny insects, including an observation box and a lid set on the observation box. Both the observation box and the lid are made of transparent material. A behavior observation layer is provided inside the observation box. A negative pressure suction device is provided on the lid. Multiple odor conduits are provided at the bottom of the observation box. A net bag containing attractant material is installed at the bottom of the odor conduits.

[0005] The behavior observation layer includes a mesh breathable layer and paper layers disposed on the upper and lower sides of the mesh breathable layer, and the paper layers are provided with multiple air flow holes.

[0006] The negative pressure suction device is used to draw the odor of the attractant into the observation box.

[0007] Preferably, the negative pressure suction device includes a suction pump and an air guide tube. The cover is provided with a mounting hole. One end of the air guide tube is installed in the mounting hole, and the other end is installed with the air inlet of the suction pump.

[0008] Preferably, the observation box and the lid are combined to form a flat oval box structure with a diameter of 9.5 cm and a height of 1 cm.

[0009] Preferably, one side of the paper layer is a smooth surface and the other side is a rough surface.

[0010] Compared with the prior art, the present invention has the following technical effects: The present invention has a simple structure and reasonable design. It uses a negative pressure suction device to put different attractant substances into the observation box, places the insects on the behavior observation layer, closes the top box lid, and observes the insects' behavior selection in response to different attractant substances. It also observes whether the attractant substances interfere with the insects' behavior selection. The whole structure is simple, easy to operate, and can more intuitively observe the insects' behavior selection. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of insect behavior according to the present invention. Detailed Implementation

[0013] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] like Figure 1 and Figure 2 As shown, an observation device for observing the aggregation behavior of tiny insects includes an observation box 1 and a lid 2 set on the observation box. Both the observation box 1 and the lid 2 are made of transparent material. A behavior observation layer 3 is set inside the observation box 1. A negative pressure suction device 4 is set on the lid 2. Multiple odor conduits 5 are set at the bottom of the observation box 1. A attractant material net bag 6 is installed at the bottom of the odor conduits 5.

[0015] The behavior observation layer 3 includes a mesh breathable layer 7 and paper layers 8 disposed on the upper and lower sides of the mesh breathable layer. Multiple air passages 9 are provided on the paper layers 8.

[0016] The negative pressure suction device 4 is used to draw the odor of the attractant into the observation box.

[0017] This invention employs a combined structure of an observation box 1 and a lid 2, forming a flat, round box structure with a diameter of 9.5 cm and a height of 1 cm. A negative pressure suction device 4 is installed on the lid 2. Multiple odor tubes 5 are installed at the bottom of the observation box 1, and a attractant material mesh bag 6 is installed at the bottom of the odor tubes 5. A behavioral observation layer 3 is installed inside the observation box 1. The behavioral observation layer 3 consists of a mesh breathable layer 7 and a paper layer 8. One side of the paper layer 8 is smooth, and the other side is rough. The smooth side facilitates adhesion to the mesh breathable layer 7, while the rough side facilitates insect crawling. The negative pressure suction device 4 includes an air pump 10 and an air guide tube 11. An installation hole is provided on the lid 2, with one end of the air guide tube 11 installed in the installation hole and the other end connected to the air inlet of the air pump 10. The negative pressure suction device 4 can draw the odor of the attractant material into the observation box.

[0018] In practice, predatory natural enemies effectively control pest populations during biological control. While capturing pests, their survival and reproduction depend not only on their prey but also on the honeydew secreted by insects. The volatile substances in the honeydew help predatory insects locate their prey, and these substances also influence the predatory insects' behavioral choices. Ants also feed on insect honeydew, such as that of pear psyllids. However, unlike pear psyllids, ants form a symbiotic relationship with them, helping the pear psyllids drive away predatory insects. Ants are both predators and symbionts; their presence reduces ladybug predation on pear psyllids.

[0019] Adult ladybugs were captured in the field and starved for 24 hours. During this period, two types of attractants (honeydew and honey) were placed in the attractant mesh bag, while the control group received no attractants. During the test, the volatiles of the attractants were pumped into the behavioral observation layer using an air pump. The starved ladybugs were then placed in the behavioral observation layer, along with ants. The top observation box was then closed for observation, during which the behavioral choices of the ladybugs or ants in different areas were recorded.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model shall be included within the scope of the present utility model.
