摘　　要：赫氏筒天牛是毛乌素沙地固沙植物塔落岩黄芪的钻蛀性害虫。此虫 2年发生 1代 ,在寄主根部越冬。 5月中旬羽化盛期用 2 5%甲胺磷乳剂 10 0 0倍稀释液喷雾杀成虫 ,防治效果可达 87.4 %。Hedysarum furxicosum Pall.var.Leave (Maxim) H.C.Fu is a major strub to fix the sand in Maowusu sandland. It is damaged by Oberea herzi Gangllauer, a wood\|boring insect. It takes two years to complete a generation, overwintering as larva inside host\|plant roots. The peak of emergence is the middle of May. Through spraying Methamidophos upon the plants, the controlling effect may reach as high as 87 4%. The harm can be effectively controlled by cutting the plant part up the ground.
