【摘要】 目的了解和掌握伍氏病蚤和穗缘端蚤的一些生物学特性,为广东省鼠疫防治提供科学依据。方法用电子天平称取蚤卵、成蚤空腹及吸血体重,并计算吸血量;用显微镜的测微尺镜下测量蚤卵的直径。结果伍氏病蚤和穗缘端蚤的卵长、短径分别为(0.636±0.035)mm、(0.360±0.017)mm和(0.536±0.024)mm、(0.256±0.011)mm;卵的平均重量分别为0.055和0.029mg;伍氏病蚤和穗缘端蚤空腹、吸饱血的平均体重分别为(0.364±0.134)mg、(0.523±0.198)mg和(0.179±0.050)mg、(0.230±0.062)mg。两种蚤的平均吸血量分别为(0.159±0.082)mg和(0.050±0.021)mg。结论伍氏病蚤成蚤及卵的体积和重量均较穗缘端蚤大,吸血量也大。更多还原

【Abstract】 Objective To study some biological characteristics of Nosopsyllus wualis laizhouensis and Acropsylla episema girshami, to provide scientific evidence for evaluating their plague-vector efficiency. Methods Weigh the flea eggs, hungry fleas and the full blood fleas using the electronic scale, and calculate sucking amount of blood; Measure the diameter of the flea egg with wee ruler of microscope. Results The long and short diameters of eggs of Nosopsyllus wualis laizhouensis were ( 0.636± 0.035)mm , ( 0.360± 0.017)mm respectively, and the Acropsylla episema girshami’s were ( 0.536± 0.024)mm , ( 0.256± 0.011)mm respectively; The average weights of the eggs were 0.055 mg , 0.029 mg respectively; The average weights of hungry fleas and the full blood fleas of Nosopsyllus wualis laizhouensis were ( 0.364± 0.134)mg , ( 0.523± 0.198)mg respectively, and Acropsylla episema girshami’s were ( 0.179± 0.050)mg , ( 0.230± 0.062)mg respectively. The average sucking amounts of blood of the two species of fleas were ( 0.159± 0.082)mg , ( 0.050± 0.021)mg respectively. Conclusion Compared with the Acropsylla episema girshami, Nosopsyllus wualis laizhouensis has heavier weight as well as larger size of egg, and the average sucking amount of blood is more.更多还原
