Abstract

Psyllids, also called plant lice, are hemipteran insects that feed on phloem sap. In addition to the direct damage they cause to plants, they are vectors of many phloem-restricted bacterial pathogens belonging to the 'Candidatus Liberibacter' spp. and 'Candidatus Phytoplasma' spp. from the apple proliferation group (16SrX). Although 'Candidatus Liberibacter' spp. cells possess cell walls unlike the phytoplasmas, they both share a reduced genome and unavailability in culture. In addition, psyllids transmit both species of bacteria in a persistent, circulative, and propagative manner. Because of the similarity of these pathosystems, electrical penetration graph (EPG) was employed to study the probing behavior of psyllids. Such studies may assist in understanding the specific interactions between the fastidious bacteria, plant hosts, and insect vectors and lead to innovative control strategies. Herein, we discuss the potential of EPG to study and understand the tritrophic interactions that secure a successful transmission from plant to plant. In addition, the use of EPG in evaluating psyllid control strategies including pesticides and tolerant varieties is reviewed.

利用电穿透图（EPG）技术的力量来了解木虱传播的挑剔细菌疾病。

木虱，也被称为植物虱，是一种以韧皮部汁液为食的半纲昆虫。它们除了对植物造成直接伤害外，还是许多韧皮部限制性细菌病原体的载体，这些细菌属于苹果增殖组的“Candidatus Liberibacter”和“Candidatus Phytoplasma”。尽管与植物原体不同，“Liberibacter候选菌”的细胞壁不同，但它们都具有减少的基因组，并且在培养中不可用。此外，木虱以持久、循环和繁殖的方式传播这两种细菌。由于这些病理系统的相似性，我们采用电穿透图（EPG）来研究木虱的探测行为。这些研究可能有助于了解挑剔细菌、植物宿主和昆虫媒介之间的具体相互作用，并导致创新的控制策略。在此，我们讨论了EPG在研究和理解确保植物间成功传播的营养相互作用方面的潜力。此外，还综述了EPG在木虱防治策略评价中的应用，包括农药和耐受性品种。

期刊介绍： Phytopathology publishes articles on fundamental research that advances understanding of the nature of plant diseases, the agents that cause them, their spread, the losses they cause, and measures that can be used to control them. Phytopathology considers manuscripts covering all aspects of plant diseases including bacteriology, host-parasite biochemistry and cell biology, biological control, disease control and pest management, description of new pathogen species description of new pathogen species, ecology and population biology, epidemiology, disease etiology, host genetics and resistance, mycology, nematology, plant stress and abiotic disorders, postharvest pathology and mycotoxins, and virology. Papers dealing mainly with taxonomy, such as descriptions of new plant pathogen taxa are acceptable if they include plant disease research results such as pathogenicity, host range, etc. Taxonomic papers that focus on classification, identification, and nomenclature below the subspecies level may also be submitted to Phytopathology.
