在防治农业害虫中,作为“抱维林”制剂作用基础的白僵菌分生孢子,为实际应用开辟了前景。因此,在详细研究了深层——表面大量培养它的方法之后,提出了对这种微生物的生物学特性要作更深入、细致研究的必要性。白僵菌(Beauveria bassiana)是昆虫的兼性寄生菌。根据生活方式,自僵菌的发育呈现如下图式:分生孢子——菌丝体——分生孢子——腐生循环;分生孢子——菌丝体——内生孢子(在患僵病昆虫的组织和血液里)——菌丝体——分生孢子(在患僵病死亡的昆虫体表和体内)——白僵菌的寄生循环。在患病昆虫的血液内形成内生孢子是半知菌中很多昆虫病原菌的特点,但是,这种
In the control of agricultural pests, Beauveria bassiana conidia, as the basis of the action of “Bavelin” preparation, opened up the prospect for practical application. Therefore, after a detailed study of the deep-surface method of culturing it in large quantities, the necessity of further and careful study of the biological characteristics of such microorganisms has been proposed. Beauveria bassiana is a facultative parasitoid of insects. According to the way of life, the development of autotrophic bacteria presents as follows: conidia - mycelium - conidia - saprophytic cycle; conidia - mycelium - endospores (in stiff disease Insect tissue and blood) - Mycelium - Conidia (body and body of insects that die of deadly disease) - Parasitic cycle of Beauveria bassiana. The formation of endospores in the blood of diseased insects is characteristic of many insect pathogens in conidia, but this
