| 中文摘要: |
| 2019年4月底,在北京、甘肃、湖北、辽宁等地一些梨园陆续发现梨树叶片异常被害状,经调查发现造成该为害状的害虫为一种未知梨木虱,在国内尚未见报道。本文简要描述了此种梨木虱的形态识别特征,测定了该害虫的16S rDNA和COⅠ基因片段序列,依据测序结果及形态特征,鉴定为苏嘎梨喀木虱Cacopsylla pyrisuga,为国内新记录种。本文还描述了该害虫的为害状、为害程度、药剂防治效果,为深入研究其发生规律和防治技术提供参考。 |
| 英文摘要: |
| At the end of April 2019, pear leaves in some orchards in Beijing, Gansu, Hubei and Liaoning provinces showed abnormal damaged symptoms. It was found that there was an unknown pear psyllid, which has not been reported in China. This paper briefly described the morphological identification characteristics of this pear psyllid. According to the 16S rDNA and COⅠ gene sequences and morphological characteristics, the psyllid was identified as Cacopsylla pyrisuga, a newly recorded species in China. This paper also described the damage characteristics, degree of hazard and chemical control effect, which could provide the reference for further study of its appearance dynamics and prevention and control technology. |
