锈色粒肩天牛[Apriona swainsoni(Hope)]是北方重要绿化树种国槐的一种蛀干害虫,主要以幼虫蛀食树干和大枝.作者通过解析枝干,发现该虫主要以2～3龄幼虫在枝干韧皮部和边材部分横向蛀食,切断树体上下输导组织,影响植株生长.该幼虫蛀道系统总体上可分为横向道、侵入道、纵向道和羽化道4部分,且侵入道、纵向道和羽化道在枝干内呈扭曲的"Z"字形.并针对人工插毒签或注射药液防治方法,提出了合理化建议.

Apriona swainsoni(Hope)is an important pest of the northern tree Sophora japonica Linn. mainly with its larvae boring the trunks and big sticks.It Was found that the main damaging stages were the 2nd and 3rd instar larvae that bored the tree from top to bottom and affected plant growth.The wormhole system could be divided into horizontal tunnel,invasive tunnel,vertical tunnel and eclosion tunnel,and the invasive tunnel,vertical tunnel and eelosion tunnel were twisted in the branches,with a"Z",shape.Reasonable suggestions were given in prevention and treatment of this pest.
