摘  要:
微生境对动物的生存与繁殖起着重要的作用。本项目选择在普洱市思茅区南岛河云南省咖啡试验示范基地,通过定点定期的取样,调查4种不同微生境条件(阳坡和阴坡、空旷和隐蔽咖啡地)下咖啡灭字脊虎天牛种群动态。结果表明:在阳坡、空旷的咖啡地,咖啡灭字脊虎天牛种群数量和危害高于其他微生境。咖啡灭字脊虎天牛各虫态抗逆性强,虫枝浸泡10 d,各虫态死亡率低,只有浸泡25 d后,死亡率达到90%以上。本文的研究结果对咖啡灭字脊虎天牛的危害机理进行了深入的探讨,揭示了微生境与咖啡灭字脊虎天牛种群动态的关系,为咖啡灭字脊虎天牛的防治提供了理论和技术框架。

摘  要:
Microhabitats pl ay an important role in the survival and reproduction of plants and animals.Xylotrechus quadripes in four microhabitats(coffee plantations with sun slope, shady slope, open, and shade) was regularly sampled in the same positions to monitor its population dynamics. The results show that the numbers and damages of X. quadripes were higher in open and sunny slope areas than in other microhabitats. X. quadripes at various developmental stage has strong resistance,showing low mortality 10 days after the infested branch was soaked, and only more than 90% 25 days after the treatment. Our results provide an insight into the damage mechanism of X. quadripes,revealing the relationship of the microhabitat and the population dynamics X. quadripes, which provided a theoretical and technical framework for the prevention and control of X. quadripes.
