SccirtothripsdorsalisHood(Thysanoptera:Thripidae)是一种侵袭性害虫,通常被称为辣椒蓟马。这种害虫具有分布在72个植物家庭中的广泛宿主,对许多具有重大经济意义的作物造成损害。在美洲,它存在于美国,墨西哥,苏里南,委内瑞拉,哥伦比亚,和一些加勒比群岛。了解具有适合该害虫生存的环境条件的区域对于植物检疫监测和检查很重要。因此,我们的目标是以美洲为重点,预测美国的分布潜力。模型是用来设计这个分布的,其中使用的环境变量在Wordclim2.1版中可用。用于建模的算法是广义加法模型(GAM),广义线性模型(GLM),最大熵(MAXENT),随机森林(RF),和Bioclim,除了合奏,其中包括所使用算法的分组。用于评估模型的指标是曲线面积(AUC),真实能力统计(TSS),索伦森得分。所有模型对所有使用的指标都有令人满意的结果(>0.8)。在北美,该模型显示了美国西海岸和纽约附近东海岸的有利区域。在南美洲,害虫的潜在分布是显著的,涵盖所有国家的地区。结论是,美国三个亚大陆有适合发生的地区。特别是,南美的大部分地区。
Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive pest that is popularly known as chilli thrips. This insect pest has a wide range of hosts distributed across 72 plant families, causing damage to numerous crops of great economic importance. In the Americas, it is present in the USA, Mexico, Suriname, Venezuela, Colombia, and some Caribbean Islands. Knowing the regions which have environmentally suitable conditions for the survival of this pest is important for phytosanitary monitoring and inspection. Thus, our objective was to forecast the distribution potential of S. dorsalis with a focus on the Americas. Models were produced to design this distribution, in which the environmental variables used were made available in Wordclim version 2.1. The algorithms used for the modeling were the generalized additive model (GAM), generalized linear model (GLM), maximum entropy (MAXENT), random forest (RF), and Bioclim, in addition to the ensemble, which consisted of the grouping of the algorithms used. The metrics used to evaluate the models were area over the curve (AUC), true ability statistics (TSS), and Sorensen score. All models had satisfactory results (> 0.8) for all metrics used. In North America, the model showed favorable regions on the west coast of the USA and east coast near New York. In South America, the potential distribution of the pest is significant, encompassing regions in all countries. It is concluded that S. dorsalis has suitable areas for the occurrence in the three American subcontinents and, in particular, a large part of South America.
