Description

Technical Field

[0001] The utility model relates to the technical field of experimental devices, in particular to a device for testing behavioral responses of lepidopteran insects. Background Art

[0002] Throughout their long evolutionary history, insects have adapted to a highly heterogeneous environment, encompassing diverse habitats, resources, and information. Adaptation to this heterogeneous environment is a key driver of their survival and evolution. Insects, through their olfactory systems, can generate a variety of behavioral responses to heterogeneous odorants, including host orientation, egg-laying, escape, feeding, and aggregation. Based on this theory, researchers have begun studying the regulatory effects of odorants on insect behavior, hoping that these effective substances will play a significant role in integrated pest management.

[0003] After searching, a wind tunnel device suitable for measuring the olfactory behavioral response of insects, such as the one disclosed in application number 201920260999.1, is found. The device includes a box body and a double-pass pipe. An outlet frame, an intermediate frame, a damping net, a honeycomb net, a dehumidification net, and a filter net are sequentially arranged in the box body in parallel with the side walls. An air supply assembly is arranged between the honeycomb net and the dehumidification net. The outlet frame and the intermediate frame are provided with corresponding holes, and the double-pass pipe connects the outlet frame and the intermediate frame through the holes. Both ends of the double-pass pipe are movably plugged with a rubber plug with a net. This wind tunnel device has the advantages of simple structure, easy portability, and low production cost. It is suitable for measuring the olfactory behavioral response of large insects including moths, butterflies, bees, and small and medium-sized insects such as flies, whiteflies, and aphids. It can be widely promoted and applied, and has broad application prospects.

[0004] However, the above method still has the following defects in actual use: it is not convenient for comparing odors. There are many small odor molecules in nature, and it is difficult to analyze which odor substances insects will have tropism behavior, which is not conducive to testing the behavioral responses of Lepidoptera insects. Utility Model Content

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: a device for testing the behavioral responses of lepidopteran insects, comprising an arena and two scent tubes arranged at the bottom thereof, the top of the arena being engaged with an upper cover, the middle of the upper cover being provided with a through hole, the surface of the through hole being provided with a gauze, the bottom of the arena being provided with two conical tubes communicating with the interior thereof, the bottom of the conical tube being placed inside the scent tube, the bottom of the scent tube being threaded with a sealing cover, the interior of the sealing cover being engaged with a scent disk, the interior of the scent disk being provided with filter paper.

[0007] The present invention is further configured as follows: an annular mounting plate is provided on the outside of the gauze, and the mounting plate is snap-fitted to the top end of the upper cover.

[0008] The present invention is further configured as follows: a first card slot is provided at the top end of the upper cover, and a first card block is provided at the bottom end of the mounting plate for engaging with the first card slot.

[0010] The present invention is further configured as follows: a second clamping block is provided inside the sealing cover, and a second clamping slot is provided at the bottom end of the odor disc for clamping and connecting with the second clamping block.

[0011] The utility model is further configured as follows: a communication pipe communicating with the interior of the scent tube is provided on the surface of the scent tube, and a flange is provided at one end of the communication pipe away from the scent tube.

[0012] In summary, the utility model has the following beneficial effects: the utility model uses the odor disk provided in the odor tube to place different odor sources, and the sealing cover is threaded, which is convenient for flexible replacement of the odor source in the odor disk, so that it is possible to analyze which odor substances insects will have tropism behavior, which is beneficial for testing the behavioral responses of Lepidoptera insects; and by providing a conical tube, it is difficult for insects to run back to the arena after entering the odor tube, and the odor tube is provided with a detachable structure, so that different odor tubes can be disassembled or replaced.
