| 摘 要： | 采用注射侵染和自然侵染法，测试了长尾斯氏线虫X-7品系、小卷蛾斯氏线虫All品系和嗜菌异小杆线虫H06品系对同一寄主大蜡螟幼虫的相互作用，及其对线虫繁殖的影响。结果表明，无论是注射侵染还是自然侵染法，对大蜡螟幼虫个体的致死竞争能力最强的是长尾斯氏线虫，其次是小卷蛾斯氏线虫，嗜菌异小杆线虫的致死能力最弱。在同一大蜡螟幼虫体内时。异小杆线虫的繁殖受斯氏线虫的不利影响较大，而两种斯氏线虫的繁殖受异小杆线虫的不利影响较小。两种斯氏线虫对各自的繁殖影响不大。 |

| Abstract: | Competitive interaction and reproduction of three species of entomopathogenic nematodes Steinernema longicaudum X-7(Sl),S.carpocapsae All (Sc) and Heterorhabditis bacteriophora H06(Hb) in Galleria larvae were determined.Whether with the natural infection method or the injection infection method,Sl infected significantly more Galleria hosts than Hb or Sc,and Sc caused higher larval mortality than Hb.When Hb was inoculated in the same Galleria larva with Steinernema genus nematodes,adverse effects on development were observed for Hb but only slightly for Steinernema genus nematodes.When Steinernema genus nematodes Sl and Sc were inoculated in the same Galleria hosts,no adverse effects occurred to the development of each of the two nematode species. |
| Keywords: | entomopathogenic nematode Galleria larva competition mortality reproduction |
