本方法具有快速、灵敏的特点，可日常用于北方根结线虫单条线虫的直接鉴定以及混合土壤线虫群体中北方根结线虫的检测。
The test is fast and sensitive, it can be routinely used for direct diagnosis of a single nematode and for detection of M. hapla in mixed soil nematode populations.
对线虫有强致死作用的菌株并不具有较高的几丁质酶活，细菌对北方根结线虫二龄幼虫的致死作用与其分泌的几丁质酶活性的高低相关性不大。
The activities of chitinase for effective and non-effective strains had not much difference, and the strains which were strongly lethal to the juveniles did not have high activity of chitinase.
