木毒蛾(Lymantria xylina Swinhoe)属于鳞翅目毒蛾科,是我省沿海木麻黄防护林的严重害虫。我们在莆田地区的福清、平潭、长乐、莆田,晋江地区的晋江、惠安,龙溪地区的漳浦,宁德地区的连江等县沿海木麻黄林的调查表明,在自然条件下木毒蛾幼虫能大量感染核多角体病毒而死亡。为了探索木毒蛾核多角体病毒对木毒蛾幼虫的致病力,为进一步开展大面积防治提供理论依据,我们对木毒蛾核多角体病毒进行了室内毒力测定与林间防治试验。现将初步结果整理如下。
Lymantria xylina Swinhoe belongs to Lepidoptera. It is a serious insect pest of Casuarina equisetifolia in the coast of our province. Our investigation of Casuarina equisetifolia in Fuqing, Pingtung, Changle, Putian, Jinjiang, Putian, Zhangpu in Longxi and Lianjiang counties in Ningde showed that in the natural conditions, Can be infected with a large number of nuclear polyhedrosis virus death. In order to explore the virulence of the woodpox moth nuclear polyhedrosis virus larvae virginal larvae, in order to further provide a theoretical basis for large-scale prevention and control, we have virulent nuclear wood polyhedrosis virus Woodpecies and forest prevention and control experiments. The preliminary results are now organized as follows.
