摘要
本文报告在半干旱低山丘陵草原景观内,用^(125)I标记达乌尔黄鼠和方形黄鼠蚤,观察方形黄鼠蚤随黄鼠体在15～29天内扩散的最大直径为760～780米,该结果接近黄鼠鼠疫血清监测的扩散范围的下限(800米),为黄鼠鼠疫疫区的处理范围由10公里缩小到4公里的设想提供了实验依据。而且实验过程说明使用^(125)I标记方法研究鼠疫动物病的流行过程和黄鼠种群及其寄生蚤的生态特点的技术是先进的,有广阔的应用前景。
Observation with 125I labelling method revealed that the greatest spreading diameters of Citellophilus tesquorum sungaris on Citellus was 760-780 m in semi-dry hill grassland in a 15-29-day period which was close the lower limit (800m) of the spreading extent of Citellus plague epizootic found by serological investigation. It provided evidence to tonarrowing the range of epidemic facus management from 10km to 4km in Citellus plague epizootic control.
