| Summary: | The pine shoot beetle, Tomicus yunnanensis, is one of the most damaging pests of Yunnan pine (Pinus yunnanensis) in southwestern China. In this study, the laboratory behavioral bioassays and field investigations were employed to examine the effects of three most abundant green leaf volatiles (GLVs)[(E)-2-hexenal, (E)-2-hexen-1-ol, (Z)-3-hexen-1-ol] from non-host trees on host location behavior of this forest pest. Y-tube olfactometer bioassays showed that adult T. yunnanensis were significantly repelled by single GLVs compound or their blends. Field experiments showed that, the increase rates of infested twigs (fed by T. yunnanensis) in all the Yunnan pine groups treated with GLVs compound were lower than control group, and had significant differences from control group. The GLVs and their blends played a negative role in the feeding behavior of T. yunnanensis in field, and decreased the damage to Yunnan pine. The above results show that, as the interrupting factors, GLVs from non-host plants have the potential to be used in field integrated managements of T. yunnanensis in the future. |
