棉铃虫核型多角体病毒,在生物防治上具有广阔的前景。现将1975年初步试验结果整理如下: 一、繁殖棉铃虫核型多角体 病毒的简单过程 棉铃虫核型多角体病毒,只能在棉铃虫幼虫体内不断增殖而致死棉铃虫,对其它害虫及益虫没有作用。在600倍显微镜下,可以看到游离的核型多角体病毒的颗粒(实际上是一个集团)。由于它是多边型而折光性强,看上去好像一颗颗游动的蓝色宝石,闪闪发光。不溶于有机溶剂,不溶于水,能溶于氢氧化钠,所以可用10％的氢氧化钠进行检验。 Helicoverpa armigera nuclear polyhedrosis virus, has a bright future in biological control. Now preliminary results of 1975 are collated as follows: First, the simple process of breeding cotton bollworm nuclear polyhedrosis virus Helicoverpa armigera nucleopolyhedrovirus can only continue to multiply in cotton bollworm larvae to death and lethal to cotton bollworm, other pests and beneficial insects No effect. Under a 600x microscope, you can see the particles of the free nuclear polyhedrosis virus (actually a group). Because it is polygonal and refraction of strong, looks like a moving blue gems, glittering. Do not dissolve in organic solvents, do not dissolve in water, soluble in sodium hydroxide, so the test can be 10% sodium hydroxide.
