摘　　要：黄角筒天牛是近年来在宁夏灵武市天然杠柳林中新发现的一种蛀干害虫,通过3年的室内饲养观察和野外实地调查,明确了黄角筒天牛在宁夏灵武市一年一代,以老熟幼虫在杠柳枝条内越冬。成虫雌雄性比为1∶0.8,每雌平均产卵39粒。卵期平均7.5d,幼虫期平均189d,蛹期平均15.6d。并根据其为害特性提出了切实可行的防控措施。Huangjiao barrel longicorn is a new stem borer pest discovered in Perifloca sepiurn in Lingwu City, Ningxia Province, in recent years. Through three years of indoor rearing and field survey, we found the pest oc- curred one generation a year in Lingwu City, and overwintered with mature larva in the branches. The ratio of fe- male and male was 1：0.8. The female laid 39 eggs on average. The duration of eggs, larva and pupa was 7.5 d, 189 d and 15.6 d, respectively. Practical control measures were proposed according to its damage characteristics.
