木毒蛾(Lymantria xylina Swinhoe)是木麻黄的重要害虫。该虫分布广,蔓延快,食量大,严重危害着我省沿海10多万亩木麻黄防护林。为了多渠道开辟木毒蛾生物防治的途径,我们于1983年5月在福建省平潭县木麻黄林内对各种类型的自然感病死亡的木毒蛾幼虫进行调查,新发现一种质型多角体病毒。通过人工感染试验,证实木毒蛾质型多角体病毒具有较强的感病力。木毒蛾质型多角体病毒(cpv)是国际上首次发现,现将观察试验结果报告如下。
Lymantria xylina Swinhoe is an important pest of Casuarina. The worm is widely distributed, spread fast, food intake, seriously endangering the coastal province of more than 10 million mu Casuarina Protection Forest. In order to open up the pathway for the biological control of the wood moth through multiple channels, we investigated various types of wood moth larvae that died of natural diseases in the Casuarina plantation in Pingtan County, Fujian Province in May 1983. We found a new type of polyhedron virus. Through artificial infection test, it was confirmed that P. moth polyhedrosis virus had strong virulence. The woodworm moth polyhedrosis virus (cpv) is the first discovery in the world, the observation test results are reported as follows.
