Abstract:
【Objective】 To carry out the evaluation of plant volatile substances on the attraction of
Agrilus mali Masumura in the hope of providing technical support for the effective monitoring of the occurrence dynamics in the forest and for the green control technology which is based on adult trapping and killing. 【Method】The experiment was conducted to attract
Agrilus mali Masumura by hanging four wavelength sticky traps and five volatiles in the wild apple orchard. 【Result】The results showed that there were significant differences in the attraction effect of 4 kinds of wavelength sticky traps and 5 kinds of volatile compounds on
Agrilus mali Masumura in the forest. The combination of (Z)-3-hexenol with egg yellow and light green sticky traps had stronger attraction effect on
Agrilus mali Masumura. The maximum attraction amount in 3 days was 66 and 63, respectively, and the average attraction number in 3 days was 24.67 and 22.48, respectively. Compared with other volatiles, there were significant differences (
P<0.05). The number of females which were trapped was significantly higher than that of males. According to the results of volatile dose test, the number of trapped
Agrilus mali Masumura showed a decreasing trend with the increase of volatile dose in a certain range. 【Conclusion】It can be seen that
Agrilus mali Masumura has a good tendency to egg yellow sticky traps and light green sticky traps, and (Z)-3-hexenol has a synergistic effect on sticky traps. The combination of (Z)-3-hexenol with egg yellow or light green a sticky traps could be used as a means of population dynamics monitoring for
Agrilus mali Masumura.
