Abstract

Males and females of C. Tesquorum altaicus, the main vector of plague in its natural focus, were experimentally studied in different seasons (spring, summer) for their capacity of block formation. The experiments used 2 groups of fleas: the insects that have been infected in last autumn and hibernated and <> insects, a that year's breeding. The investigations demonstrated that the hibernated fleas had insignificant differences (P>0.05) in the rates of block formation by sex in spring and early summer. Among the <> fleas, a that year's breeding, the males with a gizzard block considerably exceeded the females in number (P<0.05) in July-August (a period of an intensified epizootic process in the focus). By seasons, the rates of block formation were 7.0 to 21.7% in males and 2.0 to 14.0% in females.

摘要

在自然疫源地中作为鼠疫主要传播媒介的阿尔泰黄鼠(C. Tesquorum altaicus)的雄性和雌性,于不同季节(春季、夏季)对其形成菌栓的能力进行了实验研究。实验使用了两组跳蚤:去年秋季感染并冬眠的昆虫以及当年繁殖的“年轻”昆虫。研究表明,冬眠的跳蚤在春季和初夏按性别划分的菌栓形成率上差异不显著(P>0.05)。在当年繁殖的“年轻”跳蚤中,7 - 8月(疫源地 epizootic 过程加剧的时期)有砂囊菌栓的雄性数量显著超过雌性(P<0.05)。按季节划分,雄性菌栓形成率为7.0%至21.7%,雌性为2.0%至14.0%。
