Abstract

Background: Due to their abundance in some environments, the blood-sucking habit and the involvement in the transmission of several diseases, blackflies of the genus Simulium (Diptera: Simuliidae) can be considered among the most annoying biting arthropods.

Methods: Following repeated attacks to humans and animals, entomological investigations were carried out in green areas of Rome and surroundings. Site and period of attacks were reported, together with the human and animal reactions to the bites.

Results: Four Simulium species have been identified through morphological or molecular analysis: Simulium intermedium, Simulium lineatum, Simulium lundstromi and Simulium ornatum (complex). Larval breeding sites were identified in small moats, where a high density of blackflies larvae and pupae was revealed.

Conclusions: Being able to thrive in highly polluted water, even in few mm depth watercourses, some blackfly species are widely distributed in the area and their bites caused mild to severe reactions to humans and animals.

黑蝇(Simulium spp.)在罗马及其周边地区(意大利中部)攻击人类和动物。

背景:由于蚋属(双翅目:蚋科)在某些环境中的大量存在、吸血习性以及参与多种疾病的传播，它们可以被认为是最令人讨厌的叮咬节肢动物之一。方法:在罗马市区绿地及周边地区，对多次发生的人畜袭击事件进行昆虫学调查。报告了袭击的地点和时间，以及人类和动物对叮咬的反应。结果:通过形态学或分子分析鉴定出4种拟南麻属植物:中间拟南麻、线状拟南麻、无底拟南麻和复拟南麻。在小护城河中发现幼虫孳生地，幼虫和蛹密度较高。结论:某些种类的黑蝇可在高污染水体中繁殖，甚至在几毫米深的水道中也能繁殖，其叮咬对人畜造成轻、重度反应。
