二次接种1×109个鼠疫菌，存活鼠在饲养168d后产仔，从父本、母本、仔鼠体内测出鼠疫F1抗体，证实了子午沙鼠♀鼠抗体可通过胎盘传递。

M.meridianus received secondary inoculation with 1 × 10 9 plague bacilli gave offsprings in survivors after feeding for 168 days . F1 antibody to plague bacillus was detected from male parent , female parent and offsprings . It demonstrated that matrilineal antibody in M.meridianus be transmitted through placenta .

结论以胴体重为指标，划分子午沙鼠年龄是一种比较可靠、适用的方法。

Conclusion It is a reliable and applicable method that trunk weight as criterion of M.meridianus were divided into age groups .

西安地区啮齿动物隶属4科16属24种，其中子午沙鼠为本地区首次报道。

Rodents population in Xi an area belong to 24 species 16 genera and 4 families . Meriones meridianus Pall is the first time being reported in the area .

体蚤高峰在温暖季节，而巢蚤高峰在寒冷季节，主要寄生于黄兔尾鼠、长爪沙鼠、子午沙鼠和布氏田鼠。

The active Peak of body flea is in the warm season , and however , the nest flea is in the cold season . It parasitize mainly for Lagurus luteus , Meriones meridianus , Meriones unguiculatus .

1983年和1984年4～5月期间，对新疆霍城县西部荒漠进行了调查：共捕获啮齿动物11种544只，其中大沙鼠和子午沙鼠是调查区啮齿类的优势种。

Surveys were made in the desert area in western Huocheng during April and May , 1984 . Five hundred and four rodents of 11 species were captured with Rhombomys opimus and Meriones meridianus as dominant species .

结论影响种群数量变动的主要因素有种群年龄组成中幼年组的百分比、怀孕率、繁殖指数以及该地区子午沙鼠、三趾跳鼠和黑线仓鼠的数量。

Conclusion The important elements of population dynamics were the population age structure , the pregnant rate , the reproductive indices and the population number of other species ( little Chinese jird , northern three-toed jerboa and striped hamster ) .

以植物营养体为主要食物的三趾跳鼠和子午沙鼠的消化率和同化率也很高，显著高于其它地区同食性种类，而接近于食种子种类。

Dipus sagitta and Meriones meridianus feeding mainly on plants are also have high digestibility ( 82.20 % ~ 85.44 % ) and assimilation ( 79.59 % ~ 82.94 % ), which is higher than those dwelling in other regions with the same food habits .
