【摘要】 该文报道了西南地区麻疯树人工林中危害叶、花、果实和根的22种有害生物种类及其危害分布。麻疯树柄细蛾Stomphastis thraustica Meyrick、麻疯树蛀梢斑螟Oncocera faecella Zeller、蓖麻夜蛾Achaea janata Linnaeus、丽盾蝽Chrysocoris grandis Thunberg、长盾蝽Scutellera perplexa Westwood、绿鳞象甲Hypomeces squamosus Fabricius、堆蜡粉蚧Nipaecoccus vastator Maskell、黑翅土白蚁Odontotermes fomosanus Shiraki、烂皮病Phomasp.、白粉病Oidium monilioides Nees、灰霉病Botrytis cinerea Pers、麻疯树叶褐斑病Cercospora malloti Ell.、麻疯树枝枯病普遍发生,麻疯树柄细蛾、麻疯树蛀梢斑螟在1~3 a生人工林危害较重,灰霉病在苗圃危害较重,黑翅土白蚁、烂皮病在个别林分已引起少数树株死亡;麻疯树枝枯病在个别林分引起树株枯死率最高达85%,是麻疯树人工林最危险的有害生物种类。通过室内和林间试验初步提出了主要有害生物的化学控灾技术。更多还原

【Abstract】 Sixteen species of pest insects and 6 diseases were found in Jatropha curca plantations in southwest China.Among them,Stomphastis thraustica Meyrick,Hypomeces squamosus,Achaea janata Linnaeus,Chrysocoris grandis,Scutellera perplexa,Oncocera faecella Zeller,Botrytis cinerea Pers,Phoma sp.,Oidium monilioides Nees were important pests and diseases.Their chemical control technology were suggested after experiments in the field.更多还原
