线虫是我省中、南部一代粘虫的优势天敌,常年寄生率一般达40%左右,高的80%左右,其寄生率高低不仅影响当地一代粘虫的发生为害程度,而且影响虫源外迁的数量,其重要性已逐渐被植保界所重视.为提高测报和防治水平及探索其应用的可能性,1975年以来,对寄生粘虫的线虫进行了初步的调查和饲养观察,现将初步研究结果简结于下:一、形态特征经初步鉴定,寄生于粘虫的线虫属索科 (Mermithidae).种名待定,暂称索线虫.
The nematodes are the predominant natural enemies of the southern and southern generation of armyworms. The perennial parasitism rate is about 40% and the height about 80%. The parasitic rate not only affects the local generation of armyworm but also affects the relocation The importance of which has gradually been taken seriously by the plant protection community.To improve the detection and control of the level and to explore the possibility of its application since 1975, the parasitic armyworm nematodes conducted a preliminary survey and feeding observations, the initial The results are summarized as follows: First, the morphological characteristics of the initial identification of parasitic on the armyworm nematode Sociology (Mermithidae) species to be determined, tentatively called cable nematode.
