| 中文摘要: |
| 四线奇尺蛾天津亚种［Chiasmia saburraria richardsi (Prout, 1908)］是新发现的为害柠条锦鸡儿(Caragana korshinskii Kom.)的重要食叶类害虫。通过室内饲养结合野外采集调查, 详细描述了蛹和成虫的外部形态特征及其两性鉴别特征。结果如下:雌蛹生殖孔位于第8腹节后缘中央, 平均长度为165 μm, 两侧平坦, 无凸起, 并且生殖孔与肛门间的距离明显大于雄蛹; 雄蛹生殖孔位于第9腹节腹面中央, 平均长度为155 μm, 生殖孔两侧各有1半圆形瘤状突起。雌成虫体长较雄成虫粗短, 前翅长较雄成虫短, 腹部末端圆筒状; 雄成虫腹部末端稍尖。 |
| 英文摘要: |
| Chiasmia saburraria richardsi (Prout, 1908), a defoliator pest on Caragana korshinskii Kom., was newly found in Ningxia, China. The morphology of pupa and adult was studied through rearing in the laboratory, the morphology of pupa and adult of pest, as well as the sex identification characteristic of pupa and adult, were reported in details in this paper. The results were as follows: in female pupa, the gonopore with smooth sides exists in the middle of the 8th abdominal segment with the average length of 165 μm, and the length of suture between 8th and 10th abdominal segment is significantly longer than that of male pupa’s suture between 9th and 10th abdominal segment. While on the male pupa, the gonopore is obviously visible on the 9th abdominal segment, with the average length of 155 μm, and with a semicircular lump on each side. The body length of female adult is shorter than that of male, and the length of forewing is also shorter. The female adult has round abdominal end, while the male adult has a forcipate one. |
