美国白蛾(Hyphantria ounea Drury)核型多角体病毒是由丹东动植物检疫所与辽宁省蚕科所先后于丹东地区采到,经室内外试验证明,对美国白蛾有较强的毒力.但能否感染柞蚕,这对蚕区的应用有着密切的关系;另外,病毒在不加任何物质的情况下,其毒力于保存期常伴有活性损失,使毒力逐渐衰减.毒力的强弱,直接影响生产上的使用效果.为此,我们做了如下试验. 一、材料与方法 (一)试验材料病毒来源由丹东动植物检疫所提供的病毒虫尸,经过虫体扩繁获得.室内对柞蚕感染
The Hyphantria ounea Drury nuclear polyhedrosis virus was collected by the Dandong Animal and Plant Quarantine Office and Liaoning Province Silkworm Clinic in the Dandong area. The indoor and outdoor tests showed that the Hyphantria ounea Drury virus is highly virulent to the American white moth. But can infect the tussah silkworm, which is closely related to the application of the silkworm area. In addition, the virulence of the virus in the preservation period often accompanied by loss of activity, the virulence gradually decayed without adding any substance. Strength and direct impact on the production of the effect of use.To this end, we have done the following test.First, the material and methods (a) test material virus source provided by the Dandong animal and plant quarantine virus worm body, obtained by propagation of parasites Indoor infection of tussah
