\section{Importance}  \textbf Utilization of infection models allow for the discovery of factors that are involved in bacterial pathogenesis and the advancement of vaccine development. Mammalian models often serves as the “gold standard” for simulating human infection. However, for high-throughput analyses, mammalian infection models can be costly. Moreover, many research institutions are not equipped to house mammals. Finally, ethical concerns and the additional paperwork that accompanies institutional oversight involving the utilization of mammals in research has discouraged many talented investigators from microbial pathogenesis research. The development of invertebrate infection models has mitigated many of these problems. In this manuscript, we detail the utilization of the orange spotted cockroach (Blaptica dubia) (\textit{Blaptica dubia})  for modeling infection with the pathogenic bacterium, Francisella tularensis. \textit{Francisella tularensis}.  This insect can survive at mammalian temperature, is easily reared and manipulated, and mutation of F. tularensis \textit{F. tularensis}  genes already shown to be important for virulence resulted in attenuation in B. dubia. \textit{B. dubia}.  We therefore contend that the B. dubia \textit{B. dubia}  infection model is superior to existing invertebrates used to study the virulence of F. tularensis \textit{F. tularensis}  and potentially other pathogenic bacteria.
