In the previous paper, the author reported that the tendency of host selection by A. beneficus shows the remarkable variation, and especially some individuals select Ceroplastes pseudoceliferus only, though they emerged from Ceroplastes rubens. In this paper, the author wishes to clarify if there are some differences in the tendencies of individuals in selecting hosts with ages and localities of Anicetus beneficus. Fig. 1 shows the relation between the ages of individuals and their tendencies of host selection. The ages of individuals are indicated in days since emergence and the tendencies are shown in R concentration ratio (see Report 4; viz. 0% of R-ratio shows that some individual selects C. pseudoceliferus only, and 100% shows C. rubens only.) From Fig. 1, we have seen that the individuals which select C. pseudoceliferus only or C. rubens only are not restricted to some specific periods of ages. These individuals are found at any time of thier lives since the first day of emergence to 25 days old. Table 1 shows distribution of the individuals belonging to the R-ratio 0% or 100%, according to the localities collected. The results seem to suggest that the individuals showing 0% or 100% are not restricted to special localities. The results of these two points suggest that the ages and localities of the individuals do not so much influence the tendency of host selection.
