The brown marmorated stink bug, Stål (Hemiptera: Pentatomidae), is native to Japan, China, Taiwan, and Korea. Its dispersion from Asia to the United States of America and Europe caused serious damage to fruit, vegetables, and high-value crops. In Greece, damages are reported in kiwi orchards in the regions of Pieria and Imathia, which are the main production areas of kiwifruit. Greek kiwifruit production is expected to increase twofold within the next years. The aim of this research is to study the terrain and canopy properties that may have an impact on the development of populations. Thus, five kiwi orchards in total were selected in the regions of Pieria and Imathia. Τen traps were installed from early June to late October within each selected kiwi orchard-two types of traps at every side of the orchards and the center. The installed traps were examined weekly and the number of the captured was recorded. During the same days, sentinel satellite images were analyzed to calculate the vegetation index, NDVI (Normalised Difference Vegetation Index), and NDWI (Normalised Difference Water Index). The results showed population variability within the kiwi orchards since the population of was higher in areas with high NDVI and NDWI values. Additionally, our research revealed that prefers to develop populations at higher altitudes at both regional and field scales. The results of this research can be used to reduce damages by in kiwi orchards using different rates of pesticides depending on the prediction of the population size. There are multiple benefits of the proposed practice, such as a reduction in the production cost of kiwifruits, an increase in farmers' profit, and environmental protection.
茶翅蝽，斯塔尔（半翅目：蝽科），原产于日本、中国、台湾和韩国。它从亚洲扩散到美国和欧洲，对水果、蔬菜和高价值作物造成了严重损害。在希腊，皮埃里亚和伊马夏地区的猕猴桃果园报告了损害情况，这两个地区是猕猴桃的主要产区。预计希腊的猕猴桃产量在未来几年将增加两倍。本研究的目的是研究可能影响其种群发展的地形和树冠特性。因此，在皮埃里亚和伊马夏地区总共选择了五个猕猴桃果园。从6月初到10月底，在每个选定的猕猴桃果园内安装了10个诱捕器——果园的每一侧和中心各安装两种诱捕器。每周检查安装的诱捕器，并记录捕获的数量。在同一时期，分析哨兵卫星图像以计算植被指数，即归一化差异植被指数（NDVI）和归一化差异水指数（NDWI）。结果表明，猕猴桃果园内存在种群变异性，因为在NDVI和NDWI值较高的地区，其种群数量较多。此外，我们的研究表明，在区域和田间尺度上，它都更喜欢在较高海拔地区发展种群。本研究结果可用于根据种群规模预测，使用不同剂量的农药来减少猕猴桃果园中茶翅蝽造成的损害。这种做法有多重好处，比如降低猕猴桃的生产成本、增加农民利润以及保护环境。
