本文研究了小卷蛾线虫、拟双角斯氏线虫、古巴斯氏线虫用大蜡螟幼虫繁殖时其脱离寄主虫体时间和离体后短期贮存对线虫侵入率及运动能力的影响。结果表明：线虫离体时间对其侵入率有一定影响，第１天离体的线虫其侵入率均大于第７天离体的线虫，这在古巴斯氏线虫中异常显著。在３０天贮存期内，３种线虫随着贮存期的延长，其侵入率逐渐提高，小卷蛾线虫和拟双角斯氏线虫一般贮存７天，古巴斯氏线虫贮存１５天，其侵入率即达到高峰，以后基本趋于稳定；经短期贮存后，除古巴斯氏线虫的运动能力无显著提高外，其它两种线虫贮存１０天后其运动能力均高于刚离体的线虫。
In this paper, we studied the effects of parasitism and in vitro storage on the nematode invasion and exercise capacity of the larvae of C. elegans, C.subergii and C.subtilis during their propagation from C. lactea larvae. The results showed that the in vitro nematode time had an impact on its invasion rate. The invader rates of nematodes in vitro on day 1 were higher than those on days 7, which was abnormally significant in C. crassa. During the storage period of 30 days, the invasion rate of three kinds of nematodes gradually increased with the prolongation of storage period, and the larvae and imago were generally stored for 7 days and the nematodes were stored for 15 days. The invasion rate Which reached the peak after the basic stability; after short-term storage, in addition to the Cuban nematode exercise capacity was not significantly improved, the other two nematodes after 10 days of storage capacity were higher than those just off-body nematodes.
