Description

Technical Field

[0001] This utility model relates to the technical field of insect olfaction measuring instruments, specifically a Y-type insect olfaction measuring instrument. Background Technology

[0002] In the process of insects searching for host plants, the odor of the host plant conveys information about the feasibility of feeding, laying eggs and other activities, which plays a key role in the insects' behavioral responses. Therefore, studying the olfactory behavior of insects can not only reveal the chemical connection between pests and host plants, but also provide new ideas and approaches for pest control, forecasting and early warning.

[0003] Currently, there are publicly available technologies for measuring insect olfaction. For example, the patent application CN207754391U, entitled "An Insect Odor Measuring Instrument," proposes that "the airflow in the measuring instrument is driven by suction, blowing, or natural ventilation. The airflow direction sequence is: air inlet pipe 5 --- attractant placement chamber 4 --- trap device 3 --- selection arm 2 --- main arm 1 --- insect release chamber 9 --- air nozzle. When using suction, the suction pump 10 is connected to the air nozzle; when using blowing..." In this mode, the blowing device is adapted and connected to the air inlet pipe 5. Insects and other animals crawl or fly against the wind after receiving the scent, and finally fall into the trap device 3 through which the insects are attracted to the scent. From the above technical content, the existing technology uses airflow to carry the insects' favorite scent, so that the insects move in the multi-branch pipe according to their sense of smell to find the scent source, thereby achieving the purpose of measurement. However, the applicant found in actual operation that the existing technology lacks intuitive detection data on the olfactory detection speed of different insects in the insect measurement process, and the detection process is not comprehensive.

[0004] Secondly, some insects, after finding the source of the odor in the test tube, will lie on the inner wall of the tube without moving further. Although the purpose of the test is achieved, cleaning the insects inside the tube is very difficult. Although the existing technology provides devices that can be disassembled for cleaning, the process of disassembly and reassembly is long and cumbersome, which reduces the detection efficiency.

[0041] Working principle:

[0042] Example 1

[0043] Before testing, all glass structures were cleaned and dried, and then tightly assembled. The suction pump 13 was turned on to remove any external odors from the interior. Simultaneously, the airtightness of each connection point was checked. The odor substance to be tested was then placed inside one odor container 7, while the other odor container 7 remained empty to serve as a blank control.

[0044] Start the air pump 13, the flow rate can be controlled to 0.3L / min, the time is 5 minutes. The air pump 13 draws the attractant scent from the two scent containers 7 into the main test tube 1 and the two support tubes 2 through the fourth connecting tube 14, the main test tube 1, the two support tubes 2, the third connecting tube 12, the second odor filter device 9, the second connecting tube 11, the first odor filter device 8, and the first connecting tube 10. The insect to be tested is placed into the main test tube 1 through the second connecting tube head 4. Then the airtight frosted plug 5 is fitted into the second connecting tube head 4 to seal it.

[0045] Turn on camera 18 in the data acquisition system to record the insects' selective behavior towards scents. The insects will then enter the insect collection bottle 6. Afterward, disassemble the insect collection bottle 6 and pour out the insects.

[0046] Example 2

[0047] Before testing, all glass structures were cleaned and dried, and then tightly assembled. The suction pump 13 was turned on to remove any external odors from the interior. Simultaneously, the airtightness of each connection point was checked. The odor substance to be tested was then placed inside one odor container 7, while the other odor container 7 remained empty to serve as a blank control.

[0048] Start the air pump 13, the flow rate can be controlled to 0.3L / min, the time is 5 minutes. The air pump 13 draws the attractant scent from the two scent containers 7 into the main test tube 1 and the two support tubes 2 through the fourth connecting tube 14, the main test tube 1, the two support tubes 2, the third connecting tube 12, the second odor filter device 9, the second connecting tube 11, the first odor filter device 8, and the first connecting tube 10. The insect to be tested is placed into the main test tube 1 through the second connecting tube head 4. Then the airtight frosted plug 5 is fitted into the second connecting tube head 4 to seal it.

[0049] The camera 18 in the data acquisition system and the timing module inside the controller 17 are turned on to record the insect's odor selection behavior and the time period of the insect's odor selection. After multiple operations, the time data of different kinds of insects' odor selection can be obtained to improve the detection effect. The insects will then enter the insect collection bottle 6. Afterwards, the insect collection bottle 6 can be disassembled and the insects poured out.
