摘要:
为探索鸭盲肠杯叶吸虫Cyathocotyle caecumalis sp.nov虫卵孵化所需的最适温度和光照, 设置每天室外日照3h、不同室温 (2836℃、2028℃、1020℃、010℃) 以及在27℃恒温、无光照条件等5个试验组进行虫卵孵化试验。结果表明:室温2836℃组和室温2028℃组的虫卵发育较好, 其孵化率分别为27.5%和25.2%, 孵化时间分别为14d和21d;室温1020℃组的虫卵发育较差, 其孵化率为5.1%, 孵化时间为28d;室温010℃组虫卵不发育;而27℃恒温、无光照条件组, 虫卵发育差, 毛蚴多死亡, 孵不出毛蚴。试验表明鸭盲肠杯叶吸虫虫卵发育的适宜条件为2036℃, 每天日照3h。
Abstract:
To test the most suitable temperature and illumination for the egg hatch of duck Cyathocotyle caecumalis sp.nov, the hatch trail was set up as 5groups under the conditions of 3hours′sunshine per day with different room temperatures (2836℃, 2028℃, 1020℃ and 010℃) as well as a constant temperature of 27℃ with no sunlight.The results showed that the egg hatchability of the groups of 2836℃ and 2028℃ were 27.5% and25.2%, whose hatching time were 14 days and 21 days, respectively;while for the group of 1020℃, eggs developed poorly:the hatchability was 5%and the hatching time was 28days;and none egg of the group of 010℃developed;as to the group of constant temperature 27℃ with no sunlight, the eggs merely developed and most of the miracidias died.This trail indicated that the most suitable condition for the egg development of duck Cyathocotyle caecumalis sp.nov was the temperature of 2036℃ with more than 3hours′sunshine per day.
