Hymenolepis populations in Peromyscus and various beetles

In the present study, laboratory demonstrations of susceptibility to infection of potential intermediate hosts are considered to provide only circumstantial evidence that these experimental hosts may also be natural intermediate hosts for tapeworms. Therefore, an important part of this work is devoted to comparing the susceptibility of various beetle species to laboratory infection and the occurrence of natural infections of H. microstomoides and H. citelli in these same beetles.
