| 中文摘要: |
| 黄脊竹蝗Ceracris kiangsu Tsai是一种危害性极大的草地和森林害虫，主要危害禾本科植物，掌握黄脊竹蝗的食性偏好可为其防控提供理论基础。本研究选取10种禾本科植物：多年生黑麦草Lolium perenne L.、高丹草Sorghum hybrid sudangrass、苏丹草Sorghum sudanense (Piper) Stapf.、扁穗雀麦Bromus cartharticus Vahl.、白茅Imperata cylindrica (L.) Beauv.、玉米Zea mays L.、青皮竹Bambusa textilis McClure、箬竹Indocalamus tessellatus (Munro) Keng f.、刚竹Phyllostachys sulphurea (Carr.) A.‘Viridis’、箭竹Fargesia spathacea Franch.，研究黄脊竹蝗不同龄期的跳蝻及成虫取食能力、取食偏好、取食频率与时间关系的差异。结果表明：黄脊竹蝗取食量随着龄期的增加而持续增加，跳蝻喜食禾本科牧草，2~5龄跳蝻取食最多的禾本科植物为白茅，3龄时开始出现暴食，5龄时达到取食峰值；成虫多喜食竹类和玉米，其中，取食偏好玉米和青皮竹，且成年雌性取食量高于雄性；黄脊竹蝗的活动时间与一天的温度与光照有密切关系，一天内取食频率会出现两个高峰期（即上午10∶00-12∶00，下午15∶00-18∶00）。研究结果为黄脊竹蝗防控提供理论基础，也为黄脊竹蝗的人工饲养及开发利用提供基础数据。 |
| 英文摘要: |
| Ceracris kiangsu Tsai is a kind of extremely harmful grassland and forest pests, which mainly harms gramineous plants. Mastering the feeding habits of C.kiangsu can provide a theoretical basis for its prevention and control. Ten species of gramineous plants were selected in this study: Lolium perenne L., Sorghum hybrid sudangrass, Sorghum sudanense ( Piper ) Stapf, Bromus cartharticus Vahl, Imperata cylindrica (L.) Beauv., Zea mays L., Bambusa textilis McClure, Indocalamus tessellatus (Munro) Keng f., Phyllostachys sulphurea (Carr.) A.‘Viridis’, Fargesia spathacea Franch. The feeding ability, feeding preference, feeding frequency feeding time between locusts and adults at different ages were studied. The results showed that the intake of C.kiangsu continued to increase with the increase of age. C.kiangsu in the second to fifth instars preferred gramineous forages. C.kiangsu in the second to fifth instars consumed the most, which began to overeat at the third instar and reached the peak at the fifth instar. Adults of C.kiangsu preferred to eat bamboos and corn, of which maize and green bamboo were preferred, and adult females eat more than males. The activity time of the yellow ridge bamboo locust was closely related to the temperature and light of the day. There were two peaks in the feeding frequency of the day (i.e., 10 a.m. to 12 a.m. and 15 p.m. to 18 p.m.). The results provide a theoretical basis for the prevention and control of C. kiangsu, and also provide basic data for the artificial breeding, development and utilization of C. kiangsu. |
