Entomopathogenic fungi are fungal species which are used as a potential source of biopesticides. These fungi produce secondary metabolites which in insects can cause disruption in the normal functioning of their bodies, disease or even death. In order to fully characterize the physiology of entomopathogenic fungi we should identify the volatile organic compounds which are involved in this process. Therefore, we conducted a qualitative and quantitative analysis of volatile compounds produced by entomopathogenic fungi. Seven different species of fungi were analyzed: Metarhizium anisopliae, Metarhizium flavoviride, Pandora sp., Isaria fumosorosea, Hirsutella danubiensis, Batkoa sp. and Beauveria bassiana. The analyses were performed using the HS-SPME/GCMS technique. In the analyzed fungi, 63 volatile compounds were identified and classified into the following groups: aldehydes, ketones, alcohols, esters, acids, terpenes and others. The results show that entomopathogenic fungi produce a wide profile of secondary metabolites. Principal Components Analysis was used to determine whether separate classes of fungi can be distinguished from one another based on their metabolite profiles.

致病性真菌是用作生物农药潜在来源的真菌。这些真菌会产生次级代谢产物，这些代谢产物会在昆虫中引起其身体正常功能的破坏，疾病甚至死亡。为了充分表征昆虫病原真菌的生理学，我们应确定该过程中涉及的挥发性有机化合物。因此，我们对昆虫病原真菌产生的挥发性化合物进行了定性和定量分析。七种不同的真菌种类进行了分析：绿僵菌，绿僵flavoviride，潘多拉，SP，棒束孢fumosorosea，被毛danubiensis，Batkoasp。和球孢白僵菌。使用HS-SPME / GC MS技术进行分析。在所分析的真菌中，鉴定出63种挥发性化合物并将其分为以下几类：醛，酮，醇，酯，酸，萜烯等。结果表明，致病真菌产生广泛的次级代谢产物。主成分分析用于确定是否可以根据其代谢产物概况将不同类别的真菌区分开。
