Aphids (Hemiptera: Aphididae) are cosmopolitan generalist pests of many agricultural crops. Their ability to reproduce rapidly through parthenogenesis allows them to quickly reach population sizes that are difficult to control. Their damage potential is further exacerbated when they act as vectors for plant pathogens, causing diseases in plants. Aphids are typically managed through the widespread use of insecticides, increasing the likelihood of short-term insecticide resistance. However, for the past few decades, entomopathogenic bacteria have been used as an alternative management strategy. Entomopathogenic bacteria have demonstrated their effectiveness for biologically suppressing insect pests, including aphids. In addition to identifying bacterial species that are pathogenic to aphids, research has been conducted on toxins such as Cry, Cyt, Vip, recombinant proteins, and other secondary metabolites with insecticidal activity. Most studies on aphids have been conducted in vitro, exposing them to an artificial diet contaminated with entomopathogenic bacteria or bacterial metabolites for periods ranging from 24 to 96 h. The discovery of new bacterial species with insecticidal potential, as well as the possibility of biotechnological applications through the genetic improvement of crops, will provide more alternatives for managing these agricultural pests in the future. This will also help address challenges related to field application.
蚜虫(半翅目:蚜科)是许多农作物的世界性多食性害虫。它们通过孤雌生殖快速繁殖的能力使它们能够迅速达到难以控制的种群规模。当它们作为植物病原体的传播媒介,导致植物生病时,其潜在危害会进一步加剧。蚜虫通常通过广泛使用杀虫剂来控制,这增加了短期内产生抗药性的可能性。然而,在过去几十年里,昆虫病原细菌已被用作一种替代管理策略。昆虫病原细菌已证明其在生物防治害虫(包括蚜虫)方面的有效性。除了鉴定对蚜虫致病的细菌种类外,还对诸如Cry、Cyt、Vip等毒素、重组蛋白以及其他具有杀虫活性的次生代谢产物进行了研究。大多数关于蚜虫的研究都是在体外进行的,将它们暴露于被昆虫病原细菌或细菌代谢产物污染的人工饲料中24至96小时不等。具有杀虫潜力的新细菌种类的发现,以及通过作物基因改良进行生物技术应用的可能性,将为未来管理这些农业害虫提供更多选择。这也将有助于应对与田间应用相关的挑战。
