为了证明分离物是否为致病菌种,我们依据“Koch氏法则”进行了大量的田间侵染致病试验。蚜霉菌如何才能被接种成功?许多科学工作者已试验了多种方法。瑞典学者Gustafsson证明,用孢子悬液喷雾接种是最容易和最好的接种方法。Yendol等比较试验了各种接种方法,他认为用蚜虫在培养物表面爬行比用顶头放射孢子法获得的死亡数高。他还指出:蚜霉 In order to prove whether the isolate is a pathogenic species, we carried out a large number of field-borne pathogenic tests according to the Koch’s Law. How can aphids be vaccinated? Many scientists have tested many ways. Gustafsson, a Swedish scholar, has shown that spray vaccination with spore suspensions is the easiest and best method of vaccination. Yendol et al. Tested various inoculation methods in comparison, arguing that using aphids to crawl on the culture surface is higher than the number of deaths obtained by the head radiosperm method. He also pointed out:
