Embodiment 1
[0040] Set up solutions of n-octanol with a volume concentration of 0%, 0.1%, 1%, and 10%, respectively, wherein 0% is a blank control (that is, mineral oil), and use rubber tubes of the same length at different necks of the four-necked flask Connect the odor source bottles with different concentrations of volatile compounds, put 40 adults at the bottom of the four-necked flask at a time, and take the single-necked bottleneck of the four-necked flask as the boundary. Crossing the boundary is considered to be induced, and every 10 minutes The number of citrus psyllids at each bottle mouth and the total amount of four bottle mouth citrus psyllids were recorded once, and the induction efficiency was calculated. Each experiment was replaced with unused psyllids and repeated three times. The statistics of the results are shown in Table 1. It can be seen from Table 1 that the 1% n-octanol solution has better attractiveness to citrus psyllids.

Embodiment 2
[0045] Use a six-arm olfactometer to compare the attracting effect of a solution of 1% n-octanol and mineral oil on citrus psyllids, and place a solution of 1% n-octanol on the two walls of the six-arm olfactometer respectively As well as mineral oil, the other four arms are discarded and the arm openings are closed. Before the experiment, the air flow rate of each arm of the six-arm olfactometer was set to 80 mL / min. 10 adults were tested in each experiment, and a total of 30 adults were tested, and the tests were carried out one by one. Put the test insects into the olfactometer and observe and record their crawling tracks. The number of times the citrus psyllids entered the selection area of the initial test was recorded as the number of times the corresponding substances entered the area, and the time when the citrus psyllids stayed in the final selection area for 3 minutes was recorded as this area. Corresponding to the final selection times of the substance. The resu...
Embodiment 3
[0049] (1) Use rubber tubes with a length of 30 cm at different mouths of four-neck flasks to connect flavor bottles containing different concentrations of trans-1,2-cyclohexanediol solutions; trans-1,2-cyclohexane The diol solution is prepared with ultrapure water, and the volume concentration is 0%, 0.1%, 1% and 10%, respectively, and 0% is a blank control;
[0050] (2) Shade the four-necked flask containing the psyllid, put about 40 adults at the bottom of the flask at a time, and use the single-necked bottleneck of the four-necked flask as the boundary. The number of citrus psyllids at each bottle mouth and the total amount of four bottle mouth citrus psyllids were recorded every 10 minutes, and the induction efficiency was calculated. Each experiment was replaced with unused psyllids and repeated three times.
[0051] The statistics of the results are shown in Table 3. According to Table 3, it can be seen that in the concentration range of 0.1-10%, trans-1,2-cyclohexane...
