| 中文摘要: |
| 昆虫卵黄原蛋白（Vitellogenins, Vg）是一种多功能的生殖发育关键调控蛋白，在不同昆虫体内的结构、合成调控及功能不尽相同。随着基因编辑技术的成熟，运用分子手段调控Vg的合成，可减少卵黄发生，降低昆虫的繁殖力，成为有效防治害虫的优势方法之一。因此，Vg及其合成调控的研究受到广泛关注。半翅目害虫是农林业的重点防治对象之一，除直接刺吸为害寄主外，其常传播植物病原体，对农业生产造成了严重危害。半翅目昆虫Vg除在生殖发育中的关键作用外，还与病原菌的传播、寄主免疫等密切相关，可成为分子水平防治半翅目害虫及其继发病害的优势靶标。因此，本文总结了半翅目昆虫Vg的合成方式、合成场所，指明了其结构上蛋白亚基数目的差异，概述了其与昆虫免疫反应、植物防御、病毒传播等有关的研究进展，总结了其合成的保幼激素（包括保幼激素受体Methoprene-tolerant和转录因子Krüppel homolog 1等关键调控因子等）、蜕皮激素和胰岛素信号通路等主要的内分泌激素调控通路，以及以营养信号调控为主的非激素调控通路，为探索半翅目害虫的分子防控手段提供理论依据。 |

| Vitellogenin (Vg) is a multifunctional biological protein tha can regulate key regulatory factors of insect reproductive development, and its structure, synthetic regulation and function are different in different insects. With the maturity of gene editing technology, the use of molecular means to regulate the synthesis of Vg, reduce the occurrence of yolk, and reduce the fertility of insects, has become one of the important advantages of effective pest control methods. Therefore, the research of Vg and its synthesis regulation has attracted extensive attention. Hemipteran pests are one of the key prevention and control objects in agriculture and forestry. In addition to directly stinging and sucking hosts, hemipteran pests often spread plant pathogens, and cause serious harm to agricultural production. In addition to its key role in reproduction and development, Vg of hemipteran insects is closely related to the spread of pathogenic bacteria and host immunity. It can be a dominant target for controlling hemipteran pest and secondary diseases that they cause at the molecular level. Therefore, this paper summarizes that the synthesis of Vg in hemipteran insects is exogenous, and the synthesis site is mainly in fat body. It also indicates differences in the number of protein bundles in its structure of Vg. The research progress related to insect immune response, plant defense and virus transmission is also reviewed. The main endocrine hormone regulation pathways such as juvenile hormone (including key regulatory factors such as juvenile hormone receptor Methoprene-tolerant and transcription factor Krüppel homolog 1), 20-hydroxyecdysone and insulin signal pathway, as well as the non-hormone regulation pathway mainly based on nutrition signal regulation, are summarized. These information can provide theoretical basis for exploring the molecular control methods of hemipteran pest. |
