The landing patterns of blood-sucking females (Diptera: Tabanidae) are largely influenced by their visual perceptions. When attacking humans, the shape of different body parts and overall brightness of the body could be the factors determining the place of blood-sucking. The visual attractiveness of the human body for tabanids was investigated through a black and a white mannequin in the Danube floodplain, Slovakia. The mannequins were covered by glue once a week. On both of the mannequins, 332 horse flies were stuck. The trapped horse flies on the mannequins belong to the genera Tabanus Linnaeus, 1758, Hybomitra Enderlein, 1922, Chrysops Meigen, 1803, Haematopota Linnaeus, 1758 and Atylotus (Linnaeus, 1767). Based on the trapped tabanids, the black mannequin is 6.06 times more attractive than the white one. The most tabanid carcasses were found on the lower limbs (56.32%) and the least occurred on the head (2.1%), the difference in their occurrence between the lower limbs and head of both mannequins was significant (P < 0.001). A similar significant difference was observed on certain parts of both mannequins on the taxonomical level of the genera Tabanus, Hybomitra, and Atylotus, the carcasses of which aggregated mostly on the lower limbs, rather than on the upper limbs and head.
吸血雌蝇(双翅目:虻科)的着陆模式在很大程度上受其视觉感知的影响。在攻击人类时,不同身体部位的形状和整体亮度可能是吸血位置的决定因素。通过在斯洛伐克多瑙河泛滥平原的一个黑人和一个白人假人身上研究虻科对人体的视觉吸引力。每周一次,假人身上会被涂上胶水。在两个假人身上,总共粘住了 332 只马蝇。粘在假人身上的被困马蝇属于虻属(Tabanus Linnaeus,1758)、斑虻属(Hybomitra Enderlein,1922)、金蝇属(Chrysops Meigen,1803)、血蝇属(Haematopota Linnaeus,1758)和黄虻属(Atylotus(Linnaeus,1767))。根据被困虻科的种类,黑人假人比白人假人更具吸引力,吸引力是白人假人的 6.06 倍。下肢(56.32%)发现的虻科尸体最多,头部(2.1%)发现的最少,两个假人下肢和头部的虻科尸体发生率差异显著(P<0.001)。在两个假人某些部位,如虻属、斑虻属和黄虻属的分类学水平上,也观察到类似的显著差异,这些虻属的尸体大多聚集在下肢,而不是上肢和头部。
