| 摘 要： | 沙蒿尖翅吉丁Sphenoptera sp.是黑沙蒿上主要的钻蛀性害虫,引起沙蒿长势下降甚至死亡。对其形态特征及生物学特征的观察和研究结果表明:该虫在宁夏1年发生1代,以各龄幼虫在被害沙蒿根部越冬。老熟幼虫于4月中下旬开始化蛹,成虫始见于5月上旬,羽化期有两个高峰,分别是5、6月下旬。成虫羽化后并不马上离开蛹室,2～3d后咬出羽化孔,钻出蛹室。成虫需取食沙蒿叶片补充营养,2～7d后开始交尾,集中在13:00-16:30,雌雄成虫均可多次交尾。幼虫常多头聚集危害同一株沙蒿。大多数老熟幼虫在距坑道端部5mm处的根部化蛹,少数在直径为5～8mm的较粗的枝条内化蛹。沙蒿尖翅吉丁幼虫期有2种寄生性天敌,蛹期和成虫期各有1种寄生性天敌。 |

| Abstract: | The artemisia buprestid,Sphenoptera sp.has become a major pest in Inner Mongolia and Ningxia in recent years,mainly damaging the stems and roots of wormwood(Artemisia ordosoca and A.sphaerocephala)during its larval stage.A preliminary study of the morphological and biological characteristics of this pest was conducted in order to control it more effectively.The results indicated that Sphenoptera sp.has one generation per year in Ningxia,and that all larval instars overwinter.Mature larvae begin to pupate in... |
