| 摘 要： | 通过室外调查和室内试验,对重庆地区松褐天牛的食性、产卵寄主、产卵选择等生物学特性进行了研究。结果表明:松褐天牛成虫喜欢在马尾松、雪松、湿地松上栖息、取食和产卵,对罗汉松、园柏和柳杉取食相对较少,对怪柳和水杉几乎不取食;室内观察显示,成虫产卵前期为(5.74 0.27)d,产卵高峰期持续时间较长(约1.5个月),而产卵始期和末期时间较短,雄虫寿命(65.11 13.37)d,雌虫寿命(75.78 15.41)d;成虫一生的产卵量(155.89 67.22)粒。对有效控制松褐天牛的发生危害和松材线虫病在西南地区的传播蔓延提供一定的理论指导。 |

| Abstract: | Biological characteristics feed habits, host of oviposition, and choice of oviposition, etc. of Monochamus alternatus were studied by field observation and lab investigation in this paper. M. alternatus prefered to rest, feed,and lay eggs on Pinus massonlana, Cedrus deodara and Pinus elliottii, less on Podocarpus macrophyllus, Sabina chinensis and Cryptomeria fortunei, hardly on Tamarix and Metasequoia.The observation in laboratory showed the preoviposition period of was (5.74±0.27) d, the peak period of oviposition lasted longer about 1.5 months, initial oviposition and final were shortest. The longevity of male was (65.11±13.37) days,while female (75.78±15.41) days. The total oviposition amount of a female was (155.89±67.22). The study may provide some theoretical instruction on the control of M. alternatus and the epidemic widespread of Bursaphelenchus xylophilus in Southwest of China. |
