The Making of Arguments The intermediate host, it had turned out, was a small amphibian that was susceptible to commercial insecticide. The Lani People The mosquito serves as the intermediate host for the parasite of yellow fever. The Making of Arguments What you have here is a Kardonian variant which has adapted to some particular intermediate host on this world. The Lani People In the latter case the insect may act as an intermediate host. Insects and Diseases A Popular Account of the Way in Which Insects may Spread or Cause some of our Common Diseases Having for years given much thought to this subject, I became some time since impressed with the view that probably in yellow fever, as in the malarial fevers, there is an "intermediate host." The Making of Arguments It still must pass through its life cycle, but its intermediate host need not be one species of snail, fish, or copepod. The Lani People Like all trematodes it has a three-stage life cycle, but unlike every other fluke, its life cycle is not fixed to definite intermediate hosts. The Lani People We have to kill its intermediate host—or hosts if it has more than one. The Lani People |
