The meadow spittlebug, Philaenus spumarius (L.) (Hemiptera: Aphrophoridae), is the main vector in Europe of the recently detected plant pathogen bacterium Xylella fastidiosa Wells et al. (Xanthomonadales: Xanthomonadaceae). While the ecology of continental populations is well documented, nothing is known about the insular populations of P. spumarius, such as in Corsica, where the bacterium was detected in 2015. Hence, in an epidemiological context, the ecology of P. spumarius has been studied in a maquis landscape in the Ajaccio region between 2017 and 2019. Adults and nymphs were almost exclusively collected on Cistus monspeliensis L. (Cistaceae). However, very few specimens were collected in summer, suggesting a movement of the adults to sheltered habitats. Unfortunately, despite several trapping methods used, the location of adult summer habitat remains unknown for the studied population. It might be tempting to destroy the central plant host of P. spumarius populations. However, as spittlebug nymphs are highly polyphagous on low-growing plant species and as the females can lay eggs in any dead plant tissues, such practice could have limited the impact. Instead, the strong relationship between P. spumarius and C. monspeliensis could be used to monitor spittlebug populations, to limit/concentrate the means of insect control, or in an agronomic context to lure insects away from crops. Maintaining natural arboreal vegetation around agronomic systems could help decrease insect abundance – and potentially, pathogen load – on cultivated species. Such hypotheses need to be further studied by landscape experiments.

阿雅克肖地区（科西嘉岛）草甸喷虱 Philaenus spumarius 的生态学 - I：春天

草甸臭虫，鸬鹚（L.）（半翅目：Aphrophoridae），是欧​​洲最近检测到的植物病原菌的主要载体苛养木霉威尔斯等人. （黄单胞菌目：黄单胞菌科）。虽然大陆人口的生态学有据可查，但对大陆人口的岛屿却一无所知。P. spumarius，例如在科西嘉岛，该细菌于 2015 年被发现。因此，在流行病学背景下，P. spumarius2017 年至 2019 年期间在阿雅克修地区的马奎斯景观中进行了研究。成虫和若虫几乎完全收集在岩蔷薇L.（岩蔷薇科）。然而，在夏季收集到的标本很少，这表明成年人向庇护栖息地移动。不幸的是，尽管使用了几种诱捕方法，但对于所研究的人群来说，成年夏季栖息地的位置仍然未知。摧毁P. spumarius人口。然而，由于 spittlebug 若虫对低生长植物物种具有高度的多食性，并且由于雌性可以在任何死亡的植物组织中产卵，因此这种做法可能会限制影响。相反，两者之间的密切关系P. spumarius和C. monspeliensis可用于监测臭虫种群，限制/集中控制昆虫的手段，或在农艺环境中引诱昆虫远离农作物。保持农艺系统周围的天然树栖植被可以帮助减少栽培物种的昆虫丰度——以及潜在的病原体负荷。这些假设需要通过景观实验进一步研究。
