本文报道不同温度下罗索线虫寄生前期幼虫可存活的时间。试验表明，在－２～２℃温度下贮存５天，９０％以上的线虫幼虫能保持其感染蚊幼虫的能力。而在２６～２８℃和１６～１８℃下，９０％的线虫仅能存活１天和２天。低温贮存方法可延长线虫的寿命并保持其感染力。
This paper reports the survival time of parasitism larvae at different temperatures. Experiments show that at -2 ~ 2 ℃ for 5 days storage, more than 90% of nematode larvae can maintain their ability to infect mosquito larvae. While at 26-28 ° C and 16-18 ° C, 90% of nematodes survived only one day and two days. Cryopreservation can prolong nematode life and maintain its infectivity.
