不同种类的照射可以明显加快昆虫和脊椎动物细胞内病毒的发展。Sabin和koch(1963)、Smirnoff(1967)等人的这些报告提醒了我们去研究X光照射在病毒多角体的生产、核蛋白朊的生产和多角体的致病力方面的效用。本试验用的病毒是从苜蓿银纹夜蛾的核多角体有机体分离,并在粉纹夜 Different types of irradiation can significantly accelerate the development of viruses in insect and vertebrate cells. These reports by Sabin and Koch (1963) and Smirnoff (1967), et al. Remind us of the utility of X-ray irradiation in the production of viral polyhedrosis, production of nuclear proteins, and the virulence of polyhedrosis. The viruses used in this experiment were isolated from nuclear polyhedrosis organisms of Autographa californica and were pulverized at night
