AN OBSERVATIONilON THE SPOTTED LEAF-CUT WEEVIL PAROPLAPODERUS PARDALIS

  • 摘要: 昆明地区的昆明朴树Celtis kunmingensis Cheng et Hong是理想的庭园观赏树木,且为造纸和人造棉的原料。近年遭受花斑切叶象Paroplapoderus parodalis Snellen von Vollenhoven的为害,严重时将昆明朴幼树的营养叶全部卷成筒巢,影响树的生长和观赏价值。花斑切叶象在文献上记载是以壳斗科多种树木为寄主植物。为害榆科植物尚属首次记载。花斑切叶象生长发育各个时期都在筒巢中,仅成虫外出活动。一年一代,成虫有越夏习性。一种茧蜂Bracon sp.寄生于其幼虫及蛹,寄生率可达60%。在防治上应加以保护利用。
