• OKAMOTO, Kiku, (Entomol. Lab., Kyoto Univ. Kyoto) The reproduction curve of host in host-parasite interacting system and parasite free system. Jap. J. Ecol. 21,197-203 (1971) Using the azuki bean weevil, Callosobruchus chinensis (L) and its larval parasite, Anisopteromalus calandrae (Howard), the population fluctuation in host-parasite interacting systems and that in parasite free systems were examined under the physical condition of 30℃ and 70% R.H.. Strictly constant quantity of larval food was supplied to each generation. In the parasite free systems, the host populations maintained nearly constant levels of their density (Fig.1), and the reproduction curves of saturation type were obtained from these population fluctuation (Fig.2). Besides the relation between parental density and progeny density in particular generations, was examined and mountainshaped reproduction curves were obtained as shown in Fig.3. Rather concentrated age distribution and narrow spaces of experimental cages may have been responsible for the appearance of this type or reproduction curve. In the host-parasite interacting systems, the relationship between the final host density in a given generation and the initial host density in the next generation was represented by a saturation curve. As the initial host density, it is resonable to use the sum of the numbers of emerged hosts, parasites and further dead corpses of the host in the beans. Thus, the reproduction curve of the azuki bean weevil was fundamentally regarded as a saturation type in the populations of both the parasite free systems and the host-parasite interacting systems.
