病毒是什么?很难以三言两语下一个确切的定义,随着岁月的推移和研究的深入,在不同时期有着不同的解释。综合现代的观点,可以认为:从生物学角度来讲,病毒是没有细胞结构的约20—300um大小的传染因子,从化学方面来说,它是一个以自身DNA或RNA作为复制的遗传物质,以旦白质作为保护外壳的粒子;从结构功能来说,它是以核苷酸构成基因组的表达因子;从增殖过来说,它只能在活体内增殖,并利用活细胞的合成抗器来合成完整的粒子。那么,什么叫昆虫病毒呢?就是以昆虫作为宿主、并在宿主种群中发生流行病的病毒。它能在昆虫体内进行从一个细胞进入另一个细胞、或从一个个体进入另一个个体的水平传播,也能进行病毒核酸自我复制的垂直传播。因为病毒是昆虫的特异性病原,可
What is a virus? It is difficult to define exactly what the next few words, with the passage of time and research, in different periods have different interpretations. From a modern point of view, it can be considered: from a biological point of view, the virus is a cell factor of about 20-300um size of the infectious agent, chemically, it is a self-DNA or RNA as a copy of the genetic material, It uses denatured particles as a protective shell; it is a structural factor that makes it a nucleotide-based genome; it proliferates and proliferates only in vivo and is synthesized using living cells Complete particle. So, what is an insect virus? It is an insect that hosts a virus that is endemic in the host population. It can be carried in insects from one cell to another cell, or from one individual to another individual’s level of transmission, but also for viral nucleic acid self-replication of vertical transmission. Because the virus is a specific pathogen of insects, can
