摘 要：
【目的】芫菁是一类重要的药用昆虫,眼斑芫菁又名黄黑小斑蝥,是我国药典中收录的一种重要的动物药。但是斑蝥的规模化人工饲养技术尚不成熟,成为限制斑蝥素类药物开发与利用的瓶颈之一,因此,我们多年来一直致力于眼斑芫菁规模化饲养技术的研究,本文旨在探究温度和土壤含水量2个基本条件对眼斑芫菁生长发育的影响。【方法】本实验在实验室内饲养眼斑芫菁,设计了5组温度和5组土壤含水量连续饲养眼斑芫菁6代。【结果】在实验中未发现眼斑芫菁滞育越冬虫态,每年可在室内繁殖3个完全世代。不同温度处理条件下,30℃下孵化率高于其他处理,达到90.01%;32℃下幼虫和蛹的发育历期最短(14和35 d),且羽化率最高(76.00%),但与30℃下无显著差异。不同土壤含水量条件下,12%的土壤含水量条件下各发育指标显著高于其他处理,卵的发育历期最短(32 d),且孵化率最高(90.11%),幼虫和蛹的发育历期最短(14和35 d),且羽化率最高(76.00%)。【结论】综上所述,在实验室内30℃的温度条件和12%的土壤含水量是眼斑芫菁卵、幼虫及蛹的发育最适环境。结果对眼斑芫菁的规模化饲养繁殖提供了技术指导,也为芫菁的生物学研究及今后斑蝥资源的开发利用奠定了理论基础。

摘 要：
【Objective】Blister beetles are important medicinal insects due to their secretion of catharidin, Mylabris Cichorii was listed as an animal drug in Chinese Pharmacopoeia. However, the artificial raising technology dramatically limits the development and utilization of the catharidin resource. Therefore, we have been committed to the research of large-scale feeding technology of Mylabris Cichorii for many years. The purpose of this paper is to explore the effects of temperature and soil moisture on the growth and development of Mylabris Cichorii.【Method】In this experiment, six generations of M. cichorii were reared continuously at five groups of temperature and five groups of soil water content. 【Result】The results showed that the larvae could finish three complete generations per year and did not enter diapause. The growth and development of M. cichorii under different temperature and soil water content were also studied. The hatching rate under 30 ℃(90.01 %) significantly was higher than that of other temperature conditions. The developmental durations of larvae and pupae(14 and 35 days, respectively) were the shortest and the emergence rate(76.00 %) was the highest under 32 ℃, but had no significant differences between these characteristics under 30℃. Under the soil water content of 12 %, all developmental characteristics were significantly higher than other conditions, with the hatching rate of 90.11 %, developmental durations of larvae and pupae of 14 and 35 days, and the emergence rate of 76.00 %.【Conclusion】 Therefore, the optimum conditions for the growth and development of M. Cichorii were 30 ℃ and the 12 % soil moisture. These results provide the basis for large-scale breeding and reproduction of M. Cichorii.
