| 摘 要： | 栗山天牛Massicus raddei（Blessig）是我国东北危害栎树的重要害虫。在对其进行生物防治研究中，通过功能反应实验方法探讨了利用寄生蜂白蜡吉丁肿腿蜂Sclerodermus pupariae Yang et Yao对栗山天牛低龄幼虫的寄生作用。结果表明：白蜡吉丁肿腿蜂在取食寄主补充营养的过程中，对栗山天牛1～2龄小幼虫的致死作用随着寄主密度的增加而显著提高，功能反应符合Holling Ⅱ型方程，平均每日最大致死量为0.53头。寄生作用功能反应符合Holling Ⅰ型方程，寻找时间21 d内的寄主密度阈限为4头。当该肿腿蜂密度固定为1头时，对栗山天牛致死作用和寄生作用的寻找效率均随寄主密度的上升而降低。当寄主密度固定不变时，随着寄生蜂密度的增加寄主的死亡数量线性升高，被寄生的寄主数量也上升，但该肿腿蜂对栗山天牛低龄幼虫致死作用和寄生作用的寻找效应均显著下降，表明白蜡吉丁肿腿蜂是防治栗山天牛低龄幼虫的良好天敌。研究结果对于合理评价白蜡吉丁肿腿蜂在生产上的控害能力和制定寄生蜂的林间释放应用技术规程提供了依据。 |

| Abstract: | Massicus raddei (Blessig) (Coleoptera: Cerambycidae) is an important wood-boring insect pest infested Quercus spp. in northeastern China. To explore the biological control approaches, parasitism of a recent described species of parasitoid, Sclerodermus pupariae Yang et Yao, on the 1st-2nd instar larvae of M. raddei was determined. The results showed that the number of killed young larvae of the longhorn beetle significantly increased along with the increase of host densities during the parasitoid adults’ feeding on hosts for supplementary nutrition. The functional response could be described by Holling type Ⅱ model, with the average maximum 0.53 host individuals killed per day. The functional response for parasitism fitted Holling type Ⅰ equation, with the upper limit of host density of 4 larvae per tube during a searching time of 21 days. When the parasitoid density was fixed as one wasp per test tube, the searching efficiencies for both killing action and parasitism on young larvae of M. raddei decreased along with the increase of host densities. When the host density was fixed, along with the increase of host densities the number of host individuals killed increased linearly and the number of parasitized host individuals also increased, whereas the searching efficiencies for both killing action and parasitism of the parasitoid on the young larvae of M. raddei decreased significantly. These findings may serve as reference for rational evaluation on the ability of S. pupariae against the pest in fields and establishment of technical criterions for natural enemy release in forests. |
