摘要：

蜻蜓是一类有较高开发利用价值的昆虫资源,为了实现蜻蜓的室内大批量饲养,本研究采用控制变量法比较了饲养密度、水质、食物以及有无依附物对锥腹蜻稚虫存活率和开始死亡时间的影响。结果表明,高密度饲养条件会加速锥腹蜻稚虫死亡,2只组的存活率显著高于4只组和8只组,8只组稚虫开始死亡时间显著早于4只组。每天换水组稚虫的存活率显著高于隔天换水组,稚虫开始死亡时间显著晚于隔天换水组。饲喂红虫能够减少锥腹蜻稚虫死亡,饲喂红虫组稚虫开始死亡时间均显著晚于饲喂蚊子组;饲养密度为8只时,饲喂红虫的稚虫存活率显著高于饲喂蚊子。放入依附物并不显著影响锥腹蜻稚虫的存活。表明饲养密度、水质、食物对锥腹蜻低龄稚虫的存活存在显著影响,锥腹蜻低龄稚虫的最佳饲养条件为:2只为一组,每天换水,用红虫作为食物。本研究结果将为锥腹蜻以及其他蜻蜓的人工饲养和开发利用奠定基础。

Abstract:

In order to explore the indoor mass rearing condition of dragonflies, a class of insect resources with high exploitation value, the effects of rearing density, water quality, food, and the presence of dependents on the survival rate and the onset time of Acisoma panorpoides nymphs death were investigated in the study. The results showed that high-density rearing conditions accelerated the mortality of Acisoma panorpoides nymphs, and the survival rate of two nymphs group was significantly higher than that of the four nymphs and eight nymphs groups. The death time of eight nymphs was significantly earlier than that of four nymphs. The survival rate of nymphs in the daily water change group was significantly higher than that in the other day water changed group, and the death time of nymphs was significantly later than that in the other day water changed group. Compared with feeding mosquito larvae, feeding red worms could reduce the death of nymphs. The death time of nymphs fed with red worms was significantly later than that fed with mosquito larvae. When there were 8 nymphs, the survival rate of nymphs fed with red worms was significantly higher than that fed with mosquito larvae.The survival of nymphs was not significantly affected by the addition of attachments. Feeding density, water quality and food had significant effects on the survival of young nymphs. The best feeding conditions for young nymphs were as follows: 2 nymph in a group, changing the water every day and using red worms as food. Our results will lay a foundation for the breeding and utilization of dragonflies, including Acisoma panorpoides.
