Zusammenfassung: | Changes in the digestive activity after detachment in nymphal Haemaphysalis longicornis were examined. The quantity of total protein decreased rapidly from the detachment day to the 9th day after detachment, and thereafter decreased slightly. The greater part of protein in the midgut was lost during the first 9 days. The major part of proteins in the midgut contents was hemoglobin and albumin. The quantity of hemoglobin was much larger than that of albumin at the detachment day, decreased rapidly until day 9 after detachment, and then was maintained at a low level. The quantity of albumin decreased at a constant rate which was conspicuously lower than that of hemoglobin. A large quantity of hematin was detected in the midgut at the detachment day. The quantity of hematin increased as hemoglobin digestion proceeded, and started to decrease rapidly from the 1st day after detaching. |
