Embodiment 1
[0037] (1) Use rubber tubes with a length of 30 cm at different mouths of four-neck flasks to connect respectively the flavor bottles with different concentrations of 2-cyclohexenone solutions; 2-cyclohexenone solutions are prepared using mineral oil, and the volume concentration 0%, 0.1%, 1% and 10% respectively, wherein 0% is a blank control (ie mineral oil);
[0038] (2) Carry out shading treatment to the four-necked flask containing the psyllid, put about 40 adults at the bottom of the flask at a time, and take the single-necked bottleneck of the four-necked flask as the boundary, and the psyllid will be regarded as being induced when it crosses 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, repeated three times, and the average value was obtained.

Embodiment 2
[0044] (1) Use rubber tubes with a length of 30 cm at different mouths of four-neck flasks to connect flavor source bottles with different concentrations of L-carvone solutions; L-carvone solutions are prepared with mineral oil, and the volume concentration is 0% respectively , 0.1%, 1% and 10%, wherein 0% is a blank control (ie mineral oil);
[0045] (2) Carry out shading treatment to the four-necked flask containing the psyllid, put about 40 adults at the bottom of the flask at a time, and take the single-necked bottleneck of the four-necked flask as the boundary, and the psyllid will be regarded as being induced when it crosses 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, repeated three times, and the average value was obtained.
[0046] The statistics of the results are...
Embodiment 3
[0051](1) Connect zone 1, zone 2 and zone 3 of the six-arm olfactory instrument to the flavor source bottle, leave the other three arms empty and close the arm opening, and zone 3 is set as the control zone;
[0052] (2) Turn on the vacuum pump, adjust the air flow rate of each arm of the six-arm olfactometer to 80mL / min, and wait until the air flow is stable;
[0053] (3) put 1% 2-cyclohexenone solution (solvent is mineral oil) in the corresponding taste source bottle of 1 district, put into 1% L-carvone solution in the corresponding taste source bottle of 2 districts ( The solvent is mineral oil), and the same amount of mineral oil is put into the corresponding flavor source bottle of zone 3 as a control.
[0054] Each experimental test was carried out head-by-head, and the number of times the psyllid entered different areas and the number of times it was in the area when it stayed motionless for 3 minutes was recorded as the test result of the citrus psyllid's chemotactic r...
