Methods to increase and preserve Dugesia tigrina for mosquito control purposes through cocoon production, mechanical sectioning and cold storage were examined. Cocoon production was an ineffective and unreliable means of increasing planarian numbers, with an average of only 0.19 cocoons containing 0.74 young produced per adult per week. In comparison, mechanical sectioning proved to be more appropriate for increasing the number of planaria. One hundred planaria averaging 8 mm in length could be sectioned into 600 segments in approximately 18 min; regeneration was achieved by approximately 94% of these segments, usually within 8 days after sectioning. Techniques were developed to store planaria at 10 degrees C until needed for field release.
研究了通过茧生产、机械切割和冷藏来增加和保存虎纹涡虫以用于控制蚊子的方法。茧生产是增加涡虫数量的一种无效且不可靠的方法，平均每只成年涡虫每周仅产生0.19个茧，每个茧含0.74只幼体。相比之下，机械切割被证明更适合增加涡虫数量。平均长度为8毫米的100条涡虫大约可在18分钟内切成600段；其中约94%的片段能够再生，通常在切割后8天内完成。已开发出将涡虫在10摄氏度下储存直至需要野外放生的技术。
