| 中文摘要: |
| 竹大象（Cyrtotrachelus spp.）是青皮竹等丛生竹种重要的蛀笋害虫。通过调查广东省广宁县竹大象的种类及危害情况，观测其生物学特征。结果表明，广宁县竹大象以竹直锥大象为主，占比99%；该虫在广宁县一年发生一代，以成虫在土中蛹室内越冬。5月中下旬成虫开始出土，6月为出土盛期；幼虫5月中旬开始孵化，9月下旬开始化蛹，蛹经14~18 d羽化，以成虫越冬。依据竹大象的发生特点，提出了针对性的防治建议。 |
| 英文摘要: |
| Cyrtotrachelus spp. is main shoot borer of sympodial bamboos such as Bambusa textilis. This paper investigated the species components, damage degree and biological characteristics of Cyrtotrachelus spp. in Guangning County of Guangdong Province. The results showed that the main specie of Cyrtotrachelus spp. in Guangning County was Cytotrachelus longimanus Fabricius, accounting for 99%, which happened one generation each year and overwintered as adults in the pupa room in soil. The adults began to climb out the soil in the middle or late May, and reached the peak period in June; the larvae hatched in middle May and pupated in late September, which emerged into adult after 14~18 days to overwinter. According to the occurrence characteristics of C.longimanus, this paper provided relevant control suggestions. |
