在害虫的综合防治中,利用昆虫病毒治虫,是安全有效的手段之一,各地已相继开展研究和应用。近年来,我们对河北省的昆虫病毒资源开展了调查、采集、试验研究,已采集分离到部分昆虫病毒,现报导如下: 一、红腹灯蛾(Spilosomα Punctorα)核型多角体病毒(NPV)。1982,83,84年分别在保定、石家庄的甘兰、芹菜、和桑树上采到病死虫。 据电镜观察:多角体形状不甚规则,呈近似三角形,四边形,六角形以至近球形。一些多角体表面有乳头状突起或凹陷,多角体直径1.6—2.4微米,平均2.1微米。核衣壳杆状,大小约330×33毫微米。此病毒国内外未见正式报导。
In the integrated pest control, the use of insect viruses pest control, is one of the safe and effective means, all over have been carried out research and application. In recent years, we conducted a survey, collection and experimental study on insect virus resources in Hebei Province, and collected and isolated some insect viruses. The reports are as follows: First, the Spilosomα Punctorα nuclear polyhedrosis virus (NPV) . 1982, 83, 84, respectively, in Baoding, Shijiazhuang, blueberry, celery, and mulberry trees to get dead insects. According to electron microscopy: polyhedron shape less regular, was approximately triangular, quadrilateral, hexagonal and nearly spherical. Some polyhedron surfaces have papillary protrusions or depressions, polyhedra 1.6-2.4 microns in diameter, an average of 2.1 microns. Core-shaped rod, the size of about 330 × 33 nm. This virus has not been officially reported at home and abroad.
