| 摘要: |
| 文章为我国首次记录帕劳条粉蚧（Trionymus palauensis）的形态特征、地理分布和寄主。对
帕劳条粉蚧的28S rDNA 部分序列进行了扩增和测序，为该虫的分子检测提供依据。该虫寄主为王草
（Pennisetum purpureum × P. americanum）等禾本科植物，对王草等牧草生长构成潜在威胁。 |

| Abstract: |
| In the paper, the morphological features, geological distribution and host plants of Trionymus
palauensis were the first record in China. In addition, 28S rDNA partial sequence was amplified and sequenced,
which provided the basis for molecular identification of this insect. The hosts of the T. palauensis were Gramineae
grasses such as Pennisetum purpureum× P. americanum, which was a potential threat to the growth of the forage. |
| Key words: Trionymus palauensis new record species Setaria palmifolia China |
