摘要: The aim of this study was to better understand the pathogenesis of the entomopathogenic fungus Beauveria bassiana (Balsamo) strain TST05 observed on the peach fruit moth (Carposina sasakii (Matsumura)), an important orchard pest. The morphological and ultrastructural characterization of the mature larvae of C. sasakii infected by B. bassiana was investigated by using light, scanning and transmission electron microscopy. The results of the study show that B. bassiana TST05 infected the host larvae mainly by penetrating the integument. The conidia of the fungus adhere easily to the area around the mouthparts and to the basal area around the acanthae on the thorax and abdomen. Observations of the host's defensive response to the fungal attack indicated that dark spots appeared on the cuticle and that melanization appeared in the hemocoel. After overcoming the host's defense system, the pathogen grew and reproduced primarily in the hemocoel. The infection spread sequentially to the internal tissues, e.g., fat body, muscle, Malpighian tubules, gut and even the silk gland. Ultimately, the larval internal organs and tissues were damaged very extensively. Finally, the fungus emerged through the cuticle of the dead insect and released conidiophores that could act as new pathogens to infect other larvae. (c) 2012 Elsevier Ltd. All rights reserved.
