effects on the development of dipylidium caninum and on the host reaction to this parasite in the adult flea (ctenocephalides felis felis).temperature was found to be a major factor affecting the development of dipylidium caninum and the presence of a host reaction of adult ctenocephalides felis felis to d. caninum. adult fleas reared at 30-32 degrees c contained fully developed metacestodes when they emerged from their cocoons. however at lower temperatures, d. caninum could not complete development until the flea hosts had spent some time on their mammalian hosts. it was the surface temperature of the mammals (31-36 degrees c) an ...19873575292
