Five aqueous suspensions with different conidia concentrations in logarithmic series were prepared. The fungus showed high virulence as it caused 100% mortality at low conidia concentration (1.5 × 102 conidia/mL). Remarkable changes in the cellular and humoral responses were also observed when adult grasshoppers were infected with the fungus. The number of hemocytes decreased significantly within 12 h after infection. In addition, the total number of granulocytes increased rapidly in the first 12 h then gradually decreased 24 and 48 h after infections, while the number of coagulocytes fluctuated over time. The infection influenced the humoral response by increasing the phenoloxidase activity. © 2011 The Authors.
