Observation on morphological characteristics and oviposition behavior of Cylas formicarius

甘薯小象甲是甘薯生产和储存期的一种重要检疫性害虫,成虫蛀食块根、嫩芽、嫩茎,幼虫蛀食甘薯和粗蔓,并可引发软腐病等其他病害,受害甘薯有腥味不能食用,对甘薯产业造成严重危害。文章对甘薯小象甲的形态和产卵特性进行拍照和描述,提供识别和鉴定依据,有利于提高基层检疫和植保人员的检疫、监测和防控能力。

Cylas formicarius is an important quarantine pest during the production and storage of sweet potato.The adults eat root tubers,tender buds and tender stems,and the larvae eat sweet potatoes and their thick vines.The damaged sweet potatoes have a fishy smell and can not be eaten.The feeding of Cylas formicarius can cause other diseases,such as soft rot,and cause serious harm to the production of sweet potatoes.In this paper,the morphology and oviposition behavior of Cylas formicarius were photographed and described to provide identification basis,which is beneficial for improving the quarantine,monitoring and pest control abilities of technicians.
