摘要： 为揭示魔芋叶柄基部被咬食进而导致整个植株感病的原因，以期揭示魔芋虫害与病害的内在关系，为大田魔芋病虫害防治提供理论依据。笔者采用田间调查与室内人工喂养试验进行证实。田间调查结果发现，在安康、汉中、宝鸡等地均发现鼠妇咬食魔芋叶柄基部进而导致魔芋感病的现象，且多发生在潮湿荫蔽的地块；室内试验表明，鼠妇主要咬食魔芋叶柄基部和叶片。此外，鼠妇对魔芋器官的咬食程度因品种不同略有差异。以上结果表明，鼠妇是一种魔芋新“害虫”，也是魔芋病害的诱导因素之一。

Abstract: The paper aims to reveal the reasons for the disease infection of the whole konjac plant caused by the petiole bases bitten by pillworm, so as to clarify the inter-relationship between insect pests and disease of konjac, and provide a theoretical basis for pest control in field. The authors adopted field investigation and indoor artificial feeding. Field investigation showed that the petiole bases of konjac were bitten by pillworm, then resulted in infection of the plant in Ankang, Hanzhong, Baoji and so forth, and most infection happened in wet and shady places; laboratory experiment showed that pillworm mainly bit konjac leaves and petiole bases. Besides, the biting degree of pillworm on konjac was different according to varieties. The above results prove that pillworm is a new kind of pest of konjac and an inducer of konjac disease.
