The European pepper moth (Duponchelia fovealis) is an invasive pest affecting crops in many countries. The use of chemicals to control D. fovealis is not only ineffective but is hazardous to the environment. The most effective way to reduce this invasive species is biological control using entomopathogenic fungi. Furthermore, the use of combining entomopathogenic fungi is a novel and underexplored approach in the field of biocontrol research. The compatibility of different strains of Beauveria bassiana, Purpureocillium lilacinum, and Isaria javanica was evaluated by forming two-fungi consortia. The pathogenicity of these consortia against D. fovealis, as well as the related enzymatic activities, were investigated. Seven consortia increased D. fovealis mortality, showing synergistic activity. One consortium formed by two strains of B. bassiana produced highest control. Moreover, these consortia also demonstrated increased chitinase and lipase activities. Higher mortality of D. fovealis by these consortia was mainly associated with enzyme production. One consortium, also formed by two strains of B. bassiana, was unique in producing lower D. fovealis mortality than the two strains alone. The potential use of entomopathogenic fungal consortia is a promising alternative approach for biological control. Most of the consortia used in this study improved control of D. fovealis, showed synergistic activity and could be a suitable strategy to control this pest.

欧洲胡椒蛾（Duponchelia fovealis）是一种影响许多国家作物的入侵性害虫。使用化学品控制D. fovealis不仅无效，而且对环境有害。减少这种入侵物种的最有效方法是使用昆虫病原真菌进行生物控制。此外，结合昆虫病原真菌的使用是生物防治研究领域中一种新的且尚未开发的方法。通过形成双真菌联合体来评估白僵菌、淡紫紫苏和爪哇不同菌株的相容性。这些财团对D. fovealis的致病性，以及相关的酶活性，进行了研究。七个财团增加了D. fovealis死亡率，显示出协同活动。由B. bassiana的两个菌株形成的一个聚生体产生了最高的控制。此外，这些财团还表现出增加的几丁质酶和脂肪酶活性。这些聚生体对D. fovealis的较高死亡率主要与酶的产生有关。一个也由B. bassiana的两个菌株组成的聚生体在生产下D. fovealis 方面是独一无二的死亡率高于单独的两种菌株。昆虫病原真菌聚生体的潜在用途是一种有前途的生物控制替代方法。本研究中使用的大多数财团改善了对D. fovealis 的控制，表现出协同活性，可能是控制这种害虫的合适策略。
