摘　　要：本研究对寄生于羊上的捻转血矛线虫卵和肝片吸虫卵在水滴中和５５～３５５℃室温内的发育能力进行了观察。结果表明，捻转血矛线虫卵在１７５～３５５℃条件下发育成幼虫仅需７～４天；肝片吸虫卵在２２～３５５℃下发育成毛蚴需１６～１０天。肝片吸虫毛蚴感染中间宿主———椎实螺后发育成尾蚴，３２～３５天游离螺体，形成感染性囊蚴。作者在上述研究的基础上，提出了防治捻转血矛线虫病和肝片吸虫病的建议。The development ability of the eggs of Haemonchus contortue and Fasciola hepatica in sheep in water drip was observed at the room temperature of 5.5℃ to 35.5℃. The results showed, it took 7 to 4 days that the Haemonchus contortus egg developed into larva at the range of 17.5℃ to 35.5℃. The development of Fasciola hepatica from egg to miracidium took 16 to 10 days at the range of 22℃ to 355℃. The miracidium of Fasciola hepatica developed into cercaria after infeeting intermediate host (Lymnaeid). The cercaria left snail 32 to 35 days after, and developed into infeetive metacercaria. The suggestiong of prevention and control of haemonchsis and fascioliasis were made.
