摘要： 云南切梢小蠹是中国西南地区一种严重危害云南松林的钻蛀性害虫。本文通过实验室内生物行为测试和野外调查,研究3种在非寄主植物中含量相对丰富的绿叶挥发性物质(E)-2-己烯醛、(E)-2-己烯醇和(Z)-3-己烯醇对云南切梢小蠹寄主定位行为的影响。Y形嗅觉仪行为试验表明,云南切梢小蠹成虫能够显著被绿叶挥发性物质的单组分或混合组分所驱避。野外试验表明,所有绿叶挥发性物质处理组的云南松受害梢增长率均低于对照组,而且与对照组相比存在显著差异。在云南切梢小蠹的野外取食行为中,绿叶挥发性物质及其混合组分表现为一种消极的干扰因子,从而降低了该虫对寄主植物云南松的危害。这表明源于非寄主植物的绿叶挥发性物质有望作为干扰因子用于云南切梢小蠹的野外综合防治。
Abstract: 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.
