| 中文摘要: |
| 人工饲养条件下,比较观察了不同养殖模式(水体、土壤)和不同温度(24℃、26℃、28℃、30℃、32℃和34℃)对菲牛蛭(Hirudinaria manillensis)交配率的影响,并进行了不同卵茧质量(<0.6 g、0.6~1.0 g、1.0~1.5 g、1.5~2.0 g、>2.0 g)及不同温度(22℃、24℃、26℃、28℃、30℃和32℃)对亲蛭卵茧孵化数、孵化率和孵化时间影响的实验。结果表明,菲牛蛭在相同温度下土壤环境中的交配率要明显高于水体环境,其中土壤环境中28℃和30℃下亲蛭具有最高的交配率;卵茧质量组中,1.0~1.5 g和1.5~2.0 g组的孵化数及孵化率最高;温度对卵茧孵化影响显著,在26℃和28℃时出现最高的孵化数和孵化率。随着温度升高,卵茧孵化时间呈逐渐下降趋势,22℃下孵化时间最长,达58 d,而30℃和32℃高温下孵化时间明显缩短,均不超过20 d。 |
| 英文摘要: |
| The mating behavior and mating rate of Hirudinaria manillensis were observed under temperature of 24℃, 26℃, 28℃, 30℃, 32℃ and 34℃, both in soil and in water. The hatching number, hatching rate and incubation period were compared among groups with different cocoon weight of <0.6 g, 0.6-1.0 g, 1.0-1.5 g, 1.5-2.0 g and >2.0 g, and under temperatures of 22℃, 24℃, 26℃, 28℃, 30℃ and 32℃, respectively. The results showed that the average mating rate of leeches in soil was significantly higher than that in water, and the highest mating rate occurred in the cases of 28℃ and 30℃ in soil. The cocoon with weights of 1.0-1.5 g and 1.5-2.0 g had the highest hatching number and hatching rate under artificial condition. In addition, temperature influenced hatching significantly, and among 6 temperature groups, the treatments of 26℃ and 28℃ yielded the highest hatching number and hatching rate. With increased temperature, the incubating period of cocoon decreased gradually. The 22℃ group had the longest incubation period of 58 d, while less than 20 d in groups of 30℃ and 32℃. |
