飞虱虫疫霉 Erynia delphacis(Hori)是水稻害虫稻褐飞虱的天敌,在田间常造成流行病,使大量褐飞虱死亡。在研究利用真菌防治害虫方面,一个很重要的问题就是如何在人工培养基上培养病原菌,并获得大量可以保存的孢子然后用于田间。本试验的重点在于用液体培养的方法获得这种菌的分生孢子,并测定了液体和固体培养的产孢量和产孢时间。 Planthopper Erynia delphacis (Hori), a natural enemy of the rice pest brown planthopper, often causes epidemics in the field and causes a large number of brown planthopper deaths. A very important issue in studying the use of fungi for the control of pests is how to cultivate pathogenic bacteria on artificial media and obtain large quantities of spores that can be preserved for later use in the field. The focus of this experiment was to obtain the conidia of this strain by liquid culture and determine the sporulation and sporulation time of the liquid and solid cultures.
