Abstract：
UNASSIGNED: Aspergillus nomiae is known as a pathogenic fungus that infects humans and plants but has never been reported as an entomophagous fungus (EPF) that can provide other functions as an endotype.
UNASSIGNED: A strain of EPF was isolated and identified from diseased larvae of Spodoptera litura in a soybean field and designated AnS1Gzl-1. Pathogenicity of the strain toward various insect pests was evaluated, especially the ability to colonize plants and induce resistance against phytopathogens and insect pests.
UNASSIGNED: The isolated EPF strain AnS1Gzl-1 was identified as A. nomiae; it showed strong pathogenicity toward five insect pests belonging to Lepidoptera and Hemiptera. Furthermore, the strain inhibited the growth of Sclerotinia sclerotiorum in vitro, a causal agent of soil-borne plant disease. It colonized plants as an endophyte via root irrigation with a high colonization rate of 90%, thereby inducing plant resistance against phytopathogen infection, and disrupting the feeding selectivity of S. litura larvae.
UNASSIGNED: This is the first record of a natural infection of A. nomiae on insects. A. nomiae has the potential to be used as a dual biocontrol EPF because of its ability to not only kill a broad spectrum of insect pests directly but also induce resistance against phytopathogens via plant colonization.

摘要：
■诺米曲霉被称为感染人类和植物的致病性真菌，但从未被报道为能够提供其他功能作为内型的食虫真菌（EPF）。
■从大豆田中的斜纹夜蛾的患病幼虫中分离并鉴定了EPF菌株，并命名为AnS1Gzl-1。评估了该菌株对各种害虫的致病性，特别是定殖植物并诱导对植物病原体和害虫的抗性的能力。
■分离的EPF菌株AnS1Gzl-1被鉴定为A.nomiae；它对属于鳞翅目和半翅目的五种昆虫害虫显示出强致病性。此外，该菌株在体外抑制了菌核病菌的生长，土传植物病害的病原体。它通过根灌溉以90％的高定殖率将植物定植为内生菌，从而诱导植物对植物病原体感染的抗性，并破坏了斜纹夜蛾幼虫的摄食选择性。
■这是对昆虫自然感染A.nomiae的第一个记录。nomiae具有用作双重生物防治EPF的潜力，因为它不仅能够直接杀死广谱的害虫，而且能够通过植物定植诱导对植物病原体的抗性。
