Abstract

Abstract: 12 different entomopathogenic fungi isolated from diseased Drosicha corpulenta Kuwana showed high virulence with 70%~90% mortality. CYT10 strain was identified based on the morphological and molecular characteristics. Conidiogenous cells were short-globose to flask-shaped and the conidiophore elongated in a long zig-zag extension after each conidium is produced. The result of Blast search indicated that the ITS and EF1-α sequence of CYT10 showed a high similarity with those of other strain of Beauveria bassiana (>95%). Phylogenetic analysis showed that it was closely related to ARSEF-1185 strain, which was belonging to B. bassiana. CYT10 strain was classified as a member of the species B. bassiana based on the morphological characteristics and analysis of DNA sequences.

Key words: Beauveria bassiana, thrip, morphological characteristics, rDNA-ITS, EF1-a
