农业生态系统的复杂性也可以通过系统和周围环境的不同土地利用来评估,作为评估景观异质性和对兴趣社区影响的相关方法,在这种情况下,昆虫。因此,这项工作的目的是验证如何在智利莴苣园艺系统的周围环境中使用土壤,在科金博地区,改变了作物的昆虫学群落。使用黄锅诱捕器进行昆虫采样(2021年2月至2022年3月)。将在七个研究的莴苣作物中的每一个上采样两个地点。定义了土地利用和土地覆盖类别:森林,水体,灌木植被,草原,贫瘠的土地,不可渗透的表面,和城市地区。在土地利用和土地覆盖分类之后,在每个数据收集点周围创建500到5,000m的缓冲区。对于数据分析,将不同类别的土地利用百分比与生态属性进行了比较:昆虫的丰度,大量的害虫,昆虫学家族和口腔器具类型的丰富性(舔吸盘,下颌骨,picker-sucker,和傻瓜)。与园艺系统相距不同距离的土地使用会影响昆虫学群落。
The complexity of the agroecosystem can also be assessed by the different land uses in the system and the surroundings, being a relevant way to assess the heterogeneity of the landscape and the effects on the community of interest, in this case, entomofauna. Thus, the objective of this work is to verify how the use of soil in the surroundings of Chilean lettuce horticultural systems, in the Coquimbo Region, alters the entomological community of the crop. Insect sampling was conducted (February 2021 to March 2022) using yellow pan traps. Two sites will be sampled on each of the seven studied lettuce crops. Land use and land cover classes were defined: Forests, water bodies, shrub vegetation, grasslands, barren lands, impermeable surfaces, and urban areas. After land use and land cover classification, buffers of 500 to 5,000 m were created around each data collection point. For data analysis, the percentages of land use of different classes were compared with the ecological attributes: Abundance of insects, abundance of insect pests, richness of entomological families and types of oral apparatus (licker-sucker, mandible, picker-sucker, and sucker). Land uses at different distances from horticultural systems affected the entomological community.
