Biological Series, Vol. 15, No, 1 Ticks 93 Haemaphysalis kitaokai ^ Collected and examined O Collection records from literature (J Combination of dbove. Map 18. Known of Haemaphysalin kitaokiii. Biology: Iwasaki et al. (1964) observed the seasonal occurrence of this tick in a pasture at the foot of Mt. Sanbe, Sliimane Prefecture. There are two peaks of adult prevalence, one is a small peak appearing early in spring to June and another more p r o m i n ent peak from October to No- vember. No larval and nymphal fomis were found in the pasture or on cattle. Kitaoka and Morii (1967a) suggest this is possibly due to the fact that the immature forms are exceptionally rapid feeders and are attached to the host for a short period of several hours. Tsuchie et al. (1966) reported observations on overwintering of this tick. On 19 November 1964, they placed jars containing 60 engorged ticks and dried, fallen leaves out-of-doors, and found (|uiescent ticks 1 cm deep under the leaves on 18 Febru- ary the following year. The 53 females which had successfully wintered oviposited in early May. Ten specimens were observed and they laid 109-1,020 (average 617) eggs during the period from 5 May until 6 June, when the av- erage outdoor temperature began to rise to 15 C at the Sanbe Pasture. Kitaoka and Morii (1967a) studied the bi- ology of this species at Kodaira, Tokyo, using material originally collected at Sanbe Pasture in November 1962. They suggested that the life cycle was probably completed in one year in nature. The following table is a summary of data from Kitaoka and Morii (1967a). Nymphs and adults were fed on calves' ears.
