昆虫病原线虫泰山 I号,是一种异小杆属(Heterorhabditis sp)线虫,1983年5月我们从山东省果树研究所苹果园土壤中分离获得。在长江以北发现此科的昆虫寄生性线虫乃是首次。它与Xenorhabdus细菌共生。寄主受线虫侵染48小时之内死亡,尸体变红,其尸体或虽已被侵染但仍能暂时爬动的? The entomopathogenic nematode Taishan I, a Heterorhabditis sp nematode, was isolated in May 1983 from the soil of the apple orchard in Shandong Institute of Pomology. It is the first time that parasitic nematodes have been found in the north of the Yangtze River. It is symbiotic with Xenorhabdus bacteria. The host died of nematode infection within 48 hours, the body became red, although the body or has been infested but can still temporarily crawl?
