Daily every leafhopper left several tens of its oral probing punctures on the host plant. The probing frequency (the number of probing punctures on the test leaf per adult in 48 hr) was influenced by enviromental conditions. The probing frequency was significantly increased or decreased according to the high or low of the temperature. The highest frequency was observed at about 30℃. It was genarally found that the probing frequency of the adult collected from the field was more frequent than that of those reared indoors, especially the adult inhabiting in the field of dent foxtail, Alopeculus aequalis SOBOLEWSKY var. amurensis OHWI was more frequently. Diurnal rythm of the feeding behavior of the leafhopper : the probing was not active in the forenoon and midnight but activity increased very much from about six to nine in the evening. Average time of the stylet inserting period was 29.2 min. and average interval between insertions was 5.1 min. The ratio of total feeding time in a given period was 84.9 per cent average. It was generally found that the probing frequency was well connected with the activity of the leafhopper.
