作为一种传统的中药材，其死亡率高、生长缓慢是制约其规模化养殖发展的最大瓶颈。首先，研究了五种不同颜色（白色、蓝色、绿色、红色和黄色）的光对幼虫生长的影响。在70.00 μmol m−2s−1的相同强度下，实验持续45天。在本试验条件下，蓝光条件下的增重率和特定生长率显著高于其他处理（P≤ 0.05）。因此，蓝光可以促进水蛭的生长。另外，在5个蓝光强度（20.00 ± 3.84、40.78 ± 4.18、53.67 ± 5.98、70.00 ± 7.26和87.33 ± 5.77 μmol m-2s-1）处理下，增重率和生长速率均随光强的增加而增加。同时，70.00和87.33 μmol m−2s− 1处理组显著高于对照组（P≤ 0.05）。在较高光强下，消化酶活性较高，抗氧化酶活性较低。这些结果表明，适合于白腐病菌培养的最佳光谱是：在生活史早期，pigra为蓝色，最适光照强度为较高的光照强度（70.00-87.33 μmol m-2s-1）。
Used as a traditional Chinese medicine, the high mortality rate and slow growth ofWhitmania pigralarvae are the most serious bottlenecks for the scale development of artificial breeding. Firstly, five light colour treatments (white, blue, green, red and yellow) were tested to determine effects of light spectrum on the growth of larvalW. pigraat the same intensity of 70.00 μmol m−2s−1. The experiment lasted for 45 days. Under our experimental conditions, the weight gain (WG) and the specific growth rate (SGR) under blue light condition were significantly higher compared with the other treatments (P≤ 0.05). It is reasonable to conclude that blue light can promote the leech growth. In addition, reared at five blue light intensity treatments (20.00 ± 3.84, 40.78 ± 4.18, 53.67 ± 5.98, 70.00 ± 7.26 and 87.33 ± 5.77 μmol m−2s−1), the WG and SGR increased with increasing intensity. Meanwhile, they were significantly higher in the 70.00 and 87.33 μmol m−2s−1treatments (P≤ 0.05). In the higher intensity light treatments, the digestive enzymes were higher and antioxidant enzymes were lower. These results suggest that the optimal light spectrum for the culture ofW. pigraduring the early life stage was blue and the optimal light intensity was higher light intensity (70.00–87.33 μmol m−2s−1).
