云南省斑翅果蝇寄生性天敌昆虫种类调查

斑翅果蝇作为危害蓝莓、杨梅、葡萄、樱桃等软皮水果的重要害虫之一,已经引起国内外广泛关注,明确斑翅果蝇寄生性天敌昆虫的种类、分布和自然寄生状况,可以为斑翅果蝇天敌的保护利用提供科学依据。本文通过在云南省斑翅果蝇适生区采集斑翅果蝇的栽培寄主和野生浆果果实,带回实验室培养5~8d,解剖果实并挑出斑翅果蝇蛹,收集其中羽化的斑翅果蝇寄生性天敌昆虫,并记录其种类和数量,计算寄生率。本研究共采集调查了45种植物果实,有15种植物果实可被斑翅果蝇危害,其中杨梅中的斑翅果蝇种群数量最大,达到96.03头/百果;共收集到5种斑翅果蝇的寄生蜂,其中幼虫寄生蜂有丽盾瘿蜂Ganaspis brasiliensis、细毛瘿蜂Leptopilina japonica和反颚茧蜂Asobara sp.,蛹寄生蜂有果蝇锤角细蜂Trichopria drosophilae和蝇蛹金小蜂Pachycrepoideus vindemmiae,寄生蜂的自然寄生率最高可达27.81%。结果表明,丽盾瘿蜂的虫口数量最多,分布最广,为斑翅果蝇的田间优势种寄生蜂。斑翅果蝇的寄生性天敌昆虫在斑翅果蝇化蛹后的1~2周达到羽化高峰期,对斑翅果蝇具有较好的自然控制作用。

基因编辑技术的发展及其在农业生产中的应用

对动植物和人类基因组的测序为功能基因组研究提供了基础数据。然而,核苷酸序列信息并不足以帮助我们了解特定的基因组元件的功能及其在表型形成中的作用。基因编辑技术能够在很大程度上解决这一问题,帮助人们快速获得新的基因组突变模式,从而以更便捷高效的方式进行功能基因组研究。对基因编辑的基本原理及常见的锌指核酸酶(ZFN)、转录激活因子样效应因子核酸酶(TALEN)和2013年出现的CRISPR/Cas9系统进行了回顾,讨论了基因编辑技术的应用历史,特别在农业应用方面,重点关注了CRISPR/Cas9系统在水稻基因编辑中的应用,阐述了CRISPR/Cas9在基因组编辑领域的问题和其他应用方面的困难,探讨了基因编辑工具在作物改良方面所面临的主要挑战和未来发展趋势。
