| 中文摘要: |
| 通过定点观察的方法，对榆沫蝉［Cnemidanomia lugubris(Lethierry)］的形态及在吉林市的周年发生规律进行了调查研究。结果表明，榆沫蝉在吉林市1年1代，以卵在枝条皮层下越冬。每年4月下旬至5月下旬严重为害榆，偶尔也为害榆叶梅、山楂等树木。并提出了防治建议。 |
| 英文摘要: |
| The morphology and annual occurrence rules of elm spittlebugs (Cnemidanomia lugubris) were investigated in Jilin City by the method of site fixed observation. The results indicated that the insect has one generation per year in Jilin and overwinters beneath the cortex of branches in the egg stage. Elm spittlebugs may cause significant damage to elm trees during late April to late May every year. Occasionally, they also do harm to flowering plum, hawthorn and some other trees. Based on the results, some control measures are put forward. |
