【摘要】 【目的】为在室内防止捕食螨逃逸,设计一种防止逃逸行为的饲养观察装置。【方法】对比研究了传统隔水式饲养装置和改进型装置在防止逃逸行为中的效果,及改进型装置对捕食螨发育及繁殖能力有无影响。【结果】改进型装置通过添加瓶塞、棉线、盖玻片组成密闭小室,可有效防止捕食螨的逃逸,逃逸率仅为3.3%。另外,使用该装置后的捕食螨生长发育及繁殖等能力与隔水式饲养法相比未受到显著影响。【结论】本文设计的饲养观察装置可在捕食螨生物学、生态学及农药抗性等基础研究中应用。更多还原

【Abstract】 [Objectives] To prevent mites escaping from the rearing platform a new setup for rearing and observing predatory mites in the laboratory was designed. [Methods] We compared the efficiency of the improved method with that of the traditional water-barrier rearing setup. In addition, the effect of the new rearing method on the development and reproduction of the mites was evaluated. [Results] The improved setup, which consisted of a medicine bottle capsule, cotton thread and glass cover, effectively prevented mites escaping(3.3 percent loss rate), but had no significant effect on development and fecundity compared to the traditional water-barrier rearing method. [Conclusion] We suggest that the improved setup be adopted for future research on the biology, ecology and pesticide resistance of predatory mites.更多还原
