Effect test

Embodiment 1

[0019] Example 1: The influence of the height of the trap on the trapping effect in the short crop field (peanut)

[0020] Take the trap and place the trap containing L-isoleucine methyl ester and (R-(-)-linalool active ingredients) on the bottom of the trap; hang the trap in the field at 19:00; lure the trap every day Count and change the sex attractant; hang the trap on the same pole where the airflow is unobstructed in the field of short-stalked crops. The height of the center position is 1m, 1.5m, 2m, 2.5m, 3m from the ground respectively. Meter.

[0021] Table 1: The effect of trap height on short-stalk crop field (peanut)

[0022] Ground clearance

[0023] It can be seen from Table 1 that 2 meters above the ground attracts the largest number of beetles, and the effect is significant compared with 1 meter, 1.5 meters, 2.5 meters and 3 meters above the ground.

Embodiment 2

[0024] Example 2: The effect of trap height on high-stalk crop field (corn)

[0025] Take the trap and place the dark gill beetle sex attractant containing the active ingredients of L-isoleucine methyl ester and (R-(-)-linalool) at the bottom of the trap; hang the trap in the field at 19:00 pm; lure the trap inside the trap every day Count and change the sex attractant; hang the trap on the same pole where the airflow is unobstructed in the field of tall crops, and hang the trap on the corn field (the height of corn is about 2 meters), and the distance from the ground is 1.9 Rice (10 cm below corn), 2 meters (parallel to corn), 2.1 meters (10 cm above corn), 2.2 meters (20 cm above corn), 2.3 meters (30 cm above corn).

[0026] Table 2: The effect of trap height on high-stalk crop fields (corn)

[0027] Ground clearance

[0028] It can be seen from Table 2 that the number of attracting scarabs 20cm higher than corn is significantly higher than other treatments. Therefore, it is r...

Embodiment 3

[0029] Example 3: The effect of hanging traps at different times on the trapping effect

[0030] The test was conducted in Laixi area on July 12, 2010. Take the trap and place a sex attractant containing the active ingredients of L-isoleucine methyl ester and (R)-(-)-linalool on the bottom of the trap; on the day of excavation of the dark gill beetle, arrive in the field from 17:00 to 21:00 Hang the trap, which is placed in the peanut field, the center position is about 2 meters above the ground.
