天敌昆虫是害虫生物防治的重要部分.纵观世界上的害虫生物防治历史,赤眼蜂是现代农林害虫生物防治研究历史上历时最长、应用范围最广、防治面积最大、治虫效果最好的一类天敌昆虫.赤眼蜂属是全世界害虫生物防治中研究最多、应用最广的一类卵寄生性天敌,广泛用于防治玉米、水稻、棉花、蔬菜以及森林害虫.国内外许多学者对其生物学和生态学特性开展了大量的基础研究工作,为应用赤眼蜂防治农林害虫奠定了理论基础.
顶梢卷叶蛾（Spilonota lechriaspis Meyrick）为苹果属的各种果树重要害虫.对果树的新梢具有重大危害.近年来有关该虫的生物防治、抗药性发展及其治理、综合治理等方面,取得了大量既典型又有普遍意义的研究成果.防治顶梢卷叶蛾主要依赖施用化学杀虫剂.但庞大的防治费用和顶梢卷叶蛾高速增长的抗药性,令其防治工作前途暗淡.目前,顶梢卷叶蛾几乎对现有的杀虫剂都产生了不同程度的抗性.抗性的产生,化学防治的失败以及对生态环境等问题的考虑,世界范围内越来越多的研究者正在寻求有效的顶梢卷叶蛾综合治理和非化学防治的新途径.
在诸多赤眼蜂中,不同的赤眼蜂对顶梢卷叶蛾的寄生效能存在差异.在赤眼蜂控制顶梢卷叶蛾的实际应用中,赤眼蜂的种类和释放蜂群的密度对防治效果影响颇大.密度过小,不能达到理想防治效果,密度过大时会产生浪费,增加成本.因此有必要筛选优良蜂种,且研究此种赤眼蜂合理的密度.本论文在此思路和研究的基础上进行,研究多种赤眼蜂对顶梢卷叶蛾卵和米蛾卵的非选择性和选择性的寄生效能,研究对顶梢卷叶蛾寄生效能高的赤眼蜂在不同益害比下对顶梢卷叶蛾卵的寄生率,通过对单只赤眼蜂寄生顶梢卷叶蛾卵能力的研究,为田间释放该种赤眼蜂选择最佳益害比提供依据.

Natural enemies is an important part of the biological control of pests.Panoramic view of the history of biological control of pests in the world,trichogramma are modern agriculture,forestry and the longest in the history of biological control of pests,applying the broadest,largest and Osamu best control for a class of natural enemy insects.Taxonomic study on the genus study on the biological control of pests in the world,the most widely used type of egg up to parasitic enemies,widely used for controlling maize,rice,cotton,vegetables,and forest pests.Many scholars at home and abroad for their biological and ecological characteristics of a large number of basic research,laying a theoretical foundation for application trichogramma controlling pests in agriculture and forestry.
Leader leaf moth (Spilonota lechriaspis Meyrick) for Apple are important pests in fruit trees.Shoot great harm to fruit trees.In recent years about the comprehensive treatment of biological control of pests,insecticide resistance development and governance,such as,has made a large number of both typical and universal significance of the research results.Controlling leaf rollers on Leader rely mainly on the effects of chemical pesticides.But a huge amount of leaf rollers on cost control and top tip resistance of high growth,so that their work prospects.At present,the Leader of leaf rollers on existing pesticides has had a different level of resistance.Emergence of resistance,chemical control of eco-environment problems and the failure of consideration,more and more researchers around the world are looking for comprehensive management of leaf rollers on effective Leader and new approaches to non-chemical control.
In many follows,different follows foliaceous moth to top tip differences between the parasitic effectiveness.In top tip follows control foliaceous moth practical application,the types and release follows the density on the control effect buzzers influential.Density is too small,cannot achieve ideal control effects of excessive,can produce the density of waste increase costs.So it is necessary to select fine bees and research such a reasonable density follows.This thesis on this idea and research is conducted on the basis of research on top of,follows seeketh foliaceous moth eggs and meters the moth eggs selectivity and selective parasitic effectiveness of top tip,foliaceous moth parasitic efficiency high in different than follows on PE against top tip foliaceous moth eggs,through the parasitic rate follows merely foliaceous moth parasitic top tip for the eggs,the ability to choose the best benefit release follows on this than provides the basis.
