The association of detection of viral antigen in the tracheal system with early dissemination of the virus was analyzed using 2 × 2 tables for each dpi. The criterion for dissemination of infection was detection of viral antigen in non-midgut tissues, including head squash tissues, fat body, and salivary glands. | ||||||||
