昆虫病毒和其它高等动、植物的病毒一样,是一类没有细胞构造的生物体,其主要成分是核酸和蛋白质。蛋白质构成病毒的外壳称为壳体。核酸在壳体之内,壳体和核酸合称核壳体,这就是病毒个体,又称病毒粒子。一种病毒只包含一种核酸,脱氧核糖核酸 Insect viruses, like other higher animal and plant viruses, are a class of non-cellular organisms that are composed mainly of nucleic acids and proteins. The shell of a protein that makes up a virus is called a shell. Nucleic acids within the shell, shell and nucleic acid together called the nuclear shell, which is the individual virus, also known as virus particles. A virus contains only one nucleic acid, deoxyribonucleic acid
