- Abstract
[ Objective ]The resources of entomopathogenic fungi from Endoclyta signifer were identified to screen out the dominant isolates with strong pathogenicity and provide references for biological control of Endoclyta signifer. [ Method ] Entomopathogenic fungi of E. signifer were isolated by common tissue isolation method. The pathogenicity test of acquired fungi against E. signifer was conducted and taxonomic position of entomopathogenic fungi was determined by morphological characteristics and rDNA ITS sequence. [ Result ]A total of 206 fungal isolates were obtained from the diseased E. signifer.They were identified as genus of Beauveria, Fusarium, Paecilomyces,Aspergillus,Penicillium,Mucor and Evlachovaea, among which isolation rate of Beauveria was 87.4% and isolation rates of other fungi were relatively low. After pathogenicity tests were completed, it showed that Beauveria bassiana was the predominant species with stronger pathogenicity. Fusarium and Evlachovaea were weakly pathogenic fungi and others were non-pathogenic fungi. B. bassiana, F. oxysporum and Evlachovaea sp. were identified by morphological characteristics and rDNA ITS sequences. Evlachovaea sp. was recorded in China for the first time. [ Conclusion ]Entomopathogenic fungi of Endoclyta signifer in Guangxi are B. bassiana, F. oxysporum and Evlachovaea sp, of which B. bassiana is the predominant species with high application value
