目的为明确冬虫夏草寄主幼虫在人工饲养期间大量死亡的时间。方法采用定期统计养虫盒内成活或死亡幼虫数量的方法。结果幼虫最初陡然降低到最低点,然后逐渐回升到最高水平,之后又缓慢回落到平均水平一直到统计结束。结论初孵幼虫大量死亡的时间是在初孵幼虫投放后1个月内。 The purpose of this study was to determine the timing of substantial death of Cordyceps host larva during artificial feeding. Methods The method of regularly counting the number of larvae that survived or died within the feeding box was used. As a result, the larvae initially dropped sharply to the lowest point, then gradually rose back to the highest level, then slowly dropped back to the average level until the statistics were over. Conclusion Newly hatched larvae died in large numbers within 1 month after the newly hatched larvae were put into operation.
