摘要：为了开发利用天敌资源防治害虫,科学而客观地评价肿腿蜂对蛀干害虫的控害作用,研究了松脊吉丁肿腿蜂(Sclerodermus sp.)对松褐天牛3龄幼虫的功能反应,建立了肿腿蜂类寄生蜂室内控害效能评价体系,并证明了其可行性。该评价体系包括供试虫源标准、寄生蜂生物学与寄生行为学观察、寄生蜂对寄主的功能反应和寻找寄主效应以及寄生蜂的忠岐指数(Y)4个部分。研究结果表明:松脊吉丁肿腿蜂具有较强的控害潜力,单头雌成虫能防治3—4头松褐天牛3龄幼虫,21d内最多可致死9.07头寄主幼虫;寄主密度对单头寄生蜂寄生作用功能反应的测定结果与对寄生作用寻找效应的测定结果以及对产卵量影响的测定结果一致;综合评价该蜂对松褐天牛3龄幼虫控制效能,释放比为1∶1(即1头肿腿蜂雌蜂:1头3龄松褐天牛幼虫)时最高,其忠岐指数Y为39.63,这可能是肿腿蜂类天敌特有的抚幼习性所致,结论也与寄生蜂生物学特性及寄生行为学观察结果相同。研究结论证明该评价体系是稳定可靠的。评价体系在利用天敌昆虫生物防治害虫时为筛选最佳寄生性天敌种类提供了可行的方法和依据。
To evaluate the control efficiency of the bethylid parasitoids in suppressing wood- borer pests for biological application of the insect natural enemy group resources, the functional response of Sclerodermus sp., （Hymenoptera. Bethylidae） on 3rd instar larvae of Monochamus alternatus Hope （Coleoptera： Cerambycidae） was studied. A consummate evaluation system of control efficiency was established and its feasibility was clarified. The evaluation system consists of four parts： the standard of experimental insects, study on biological characters of parasitism behavior of the bethylid, the functional response of parasitoid and Zhongqi Index. The results indicated that one bethylid female could control 3-4 3rd instar larvae of M. alternates, the maximum quantity of hosts had been killed was 9.07 in 21days, the Sclerodermus sp. had great potential for control the wood borer pest. The result of parasitism functional response on one parasitoid wasp to different diversities of hosts was consistent to the host-searching efficiency and similar to the impact on the fecundity. Comprehensive evaluation indicated that the control efficiency of the bethylid on 3rd instar larvae of M. alternates was highest at 1 ： 1 （releasing number property of parasitoid and its host）, the Zhongqi Index was 39.63, which probably was caused by the bethylid＇s brood guarding behavior. That has certain similary with the observation on biological characters of parasitic behavior. Above all, the evaluation system is steadily, parasitic wasp species for biological control application. which could be used for biological control to screen out optimal
