Description

Technical Field

[0001] This invention relates to the technical field of odor tropism comparison experimental apparatus, specifically to a multi-channel mole cricket odor tropism comparison experimental apparatus and its usage method. Background Technology

[0002] The mole cricket (Modo cricket) is a major underground pest that seriously damages crop roots, leading to missing seedlings and broken rows. Chemical control is currently one of the main methods, but indiscriminate use of pesticides can easily cause environmental pollution, increased pesticide resistance, and damage to non-target organisms. Therefore, effectively screening pesticides that have a significant attraction or repulsion effect on the mole cricket is a prerequisite for green pest control.

[0003] Existing tropism testing devices are mostly Y-shaped or T-shaped olfactory instruments, which can only test two odor sources simultaneously, resulting in low efficiency, small sample size, and poor repeatability. Although some improved multi-channel devices can expand the number of channels, they generally have the following problems: severe cross-interference of odors, no effective isolation between adjacent channels, and odor diffusion leading to inaccurate tropism judgment; changing the food is complicated, requiring complete disassembly or opening of the main chamber, which easily disturbs the test insects and affects the continuity of behavior.

[0004] Therefore, there is an urgent need for an experimental device that is structurally sound, has good isolation properties, is easy to operate, and can simultaneously compare the tactic reactions of multiple reagents. Summary of the Invention

When the long strip-shaped protrusion on the outer wall of the spline engages with the first strip-shaped groove on the inner wall of the inner cylinder of the rotating assembly, the rotating shaft drives the spline and the rotating assembly to rotate together.

[0016] This invention also provides a method for using a multi-channel mole cricket odor tropism comparison experimental device, comprising the following steps: Place different baits in different bait boxes and place the bait boxes in the bait box compartment; The gear fan assembly accelerates the release of the bait's scent, with different scents diffused through their respective horn vents into their respective mole cricket crawling channels. Several mole crickets are released through the release port on the shell. The mole crickets crawl along the crawling channel attracted by the scent to the weighing plate, where the weighing plate collects data. When the mole crickets on the weighing plate reach the set weight, they transmit a signal to the controller. The controller then starts the motor to drive the rotating shaft to rotate. At the same time, the free end of the lever forces the spline to move upward and fit tightly with the rotating assembly, causing the rotating assembly to rotate. When the first position sensor in the adjacent mole cricket crawling channel and the second position sensor on the spline are positioned opposite each other, the controller controls the motor to stop and the rotating shaft to stop rotating in order to collect data on the next weighing plate.

[0017] The present invention has the following advantages due to the adoption of the above technical solutions: (1) The present invention sets up multiple independent odor channels (such as 6 channels), which can simultaneously compare the tactic response of various odor sources such as water control, sugar water of different concentrations, plant volatiles and low-toxicity pesticides to the mole cricket, significantly improving the sample throughput and statistical power of a single experiment, and avoiding the limitation of traditional "Y-type" or "T-type" olfactory instruments that can only compare two pairs. (2) In this invention, each odor channel is structurally independent. The channel has a non-smooth inner wall to reduce airflow disturbance. Combined with a precisely controlled fan blowing system and a timed start-stop mechanism, it ensures that the odor diffuses directionally along a single channel, greatly reducing odor crosstalk between adjacent channels and ensuring the accuracy of tropism judgment. (3) In this invention, the odor in each bait box is diffused by a micro fan driven by a quantitative wind speed. Combined with the standardization of bait soaking concentration, the odor release rate between different treatment groups is relatively consistent. At the same time, the "position sensor + motor pause" mechanism avoids the rapid mixing of high-concentration odors in the initial stage and ensures the stability of the environmental odor background in the early stage of the experiment. (4) The bottom of the channel in this invention is integrated with a high-sensitivity electronic weighing plate. When the mole cricket enters the channel and stays, its weight triggers a preset threshold (such as the first group of grams), automatically identifying the tropism behavior. No manual intervention or continuous visual tracking is required, which reduces the impact of human interference on the behavior of the test insects and improves the ecological validity of the experiment. (5) In this invention, when the amount of insect attracted to a certain channel reaches the set threshold, the system automatically triggers the switching of the rotating channel through the lever-spline linkage mechanism, so that the channel is temporarily removed from the main experimental area to avoid the data imbalance of other channels caused by continuous attraction; at the same time, the electronic weighing plate has an "automatic zeroing" function to prevent the same insect from repeatedly triggering the rotation and to ensure that each response is unique and effective. (6) The top delivery port and transparent shell design of the present invention support full-process visual observation and can be connected to an external camera or behavior recording system to facilitate data collection and retrospective analysis.
