锈色粒肩天牛对不同植物的选择性实验

锈色粒肩天牛是一种破坏性极强的钻蛀性害虫。为进一步明确它对4种常见植物国槐、香花槐、旱柳和苦楝选择性的差异,首先通过嗅觉仪进行了锈色粒肩天牛对4种植物的招引实验,然后进行野外观察,研究结果表明:国槐对锈色粒肩天牛有显著的招引效果;香花槐有一定招引作用,但差异并不显著;旱柳既无招引作用也无驱避作用;而苦楝对其还表现出驱避作用。因此,我们建议选用旱柳和苦楝作为国槐的隔离树种。本研究结果对锈色粒肩天牛的防治具有重要意义,而且还能为植物源生物药剂的研制提供依据。

Preliminary Study on the Selectivity of Apriona swainsoni on Four Different Plants

Apriona swainsoni is a devastating borer pest.To further understand the selectivity variation of Apriona swainsoni to four different plants, i.e.the Sophora japonica, Robinia pseudoacacia, Salix matsudana and Melia azedaeach, we firstly used the olfactometer to conduct the attractive experiment.Then, the field observation was implemented.The results showed that the Sopho-ra japonica had significantly attractive effect;the Robinia pseudoacacia had certain attractive effect, but the difference was not sig-nificant; the Salix matsudana had no effect on the Apriona swainsoni, while the Melia azedaeach demonstrated repellent effect. Therefore, we suggest that the Apriona swainsoni can be regard as the isolated trees.The results of this study not only have signifi-cant implications to the prevention of Apriona swainsoni, but also can provide theoretical basis for the development of plant-derived biopharmaceuticals.
