Ecological Consequences of a New Coffee Production Technology

PI建议调查三种类型的 咖啡种植对当地昆虫动物区系与 区 初步规划活动包括：文献综述， 网站位置、必要的权限和协作 机构、方法试验、初步数据 收集、数据分析和解释、实验重新设计 并撰写最终提案。 第一年的活动 将涉及3个管理系统的比较：1） 传统的农林复合系统，有多种遮荫树 与咖啡间作; 2）农林系统，只有一个 通过定期修剪集中管理的遮荫树种; （3）无遮荫树的单作咖啡。 代表 农场将被选中。 与蚂蚁相关的基线数据 群落、病虫害密度和分布 将使用标准抽样方法收集。 光子通量 密度和CO2吸收将直接使用 太阳能电脑程序。 卫星照片将用于 确定种植在单一文化的国家的面积 系统 施氮量的效应和 杀虫剂杀虫剂的应用对蚂蚁集群和 将在今后几年中对害虫进行研究。

The PI proposes to investigate the effects of three types of coffee cultivation on the native insect fauna associated with the area. Preliminary planning activities include: literature review, site location, necessary permissions and collaborating institutions, experimentation with methodologies, preliminary data gathering, data analysis and interpretation, experiment redesign and writing of final proposal. Activities during the first year will involve the comparison of 3 management systems: 1) Traditional agroforestry system with a variety of shade trees interplanted with coffee; 2) the agroforestry system with just one shade tree species intensively managed through periodic pruning; and 3) monocultural coffee with no shade tree. Representative farms will be selected. Base-line data related to ant assemblages, insect pest and disease densities and distributions will be gathered using standard sampling methods. Photon flux density and CO2 uptake will be calculated directly using the Solarcal computer program. Satellite photographs will be used to determine the area of the country planted in the monocultural system. The effect of nitrogen fertilization and the effect of pesticide insecticide applications on the ant assemblage and on pests will be studied in subsequent years.
