| 摘 要： | 蚱蝉每5年一代,以卵和若虫在枝条和土中越冬。卵期260—340d,6月中下旬孵化。若虫四龄,老熟若虫7月初出土羽化,7月中下旬达盛期。成虫7月中旬产卵为害,8月上旬达盛期。成虫寿命45—60d,雌雄比1:1。其危害与树种、树龄、气候等关系密切。防治措施:利用天敌,选择抗蝉害树种,修剪卵枝,于林下喷施农药,浇灌氨水,人工捕捉出土若虫等。

| Abstract: | Cryptotympana atrata (Fabr. ) is an important branch-boring pest of poplar, elms, apple etc. Observations have shown that five years are required for the pest to complete a generation. The pest overwinters as larva in the soil and as egg in the branch. The adult occurs from early July to mid-August. Oviposition begins in mid-July; the peak of egg-laying is in mid-August; the egg period is from 260 to 340 days. The longevity of the adult is from 45 to 60 days. The sex ratio is 1:1. The adult male likes to sing. The adults have the characteristics of cybotaxis and the sociality} the space distribution pattern of the adult in the forest coincides with the aggregated negative binomial distribution. The effective control measures include the selection of the varieties of poplar resistant to the damage of the cicadj cutting branches with eggs in winter; dusting or spraying chemical pesticides on the host tree crown during oviposition period and on the forest floor during nymphal emerging period, and watering the soil with ammonia water in late June and interpianting corn young tree. |
