The current study aimed at molecular identification and comparing the diversity of arthropods communities between pig and sheep carcasses during the cold and warm season in KwaZulu-Natal province of South Africa. Adult arthropods found on and around the carcasses were collected using either fly traps or forceps. Molecular analyses confirmed the identification of twelve arthropod species collected from both sheep and pig carcasses during the cold season. Results showed that 11 of 12 arthropod species were common in both sheep and pig carcasses, with exception to (Coleoptera: Scarabaeidae) (Linnaeus, 1767) and (Diptera: Muscidae) (Rondani, 1871) species which were unique to sheep and pig carcasses respectively. However, during the warm season, the sheep carcass attracted more arthropod ( = 13) species as compared to the pig carcass. The difference in the obtained arthropod was due to the presence of which was also unique to the sheep carcass during this season. Furthermore, there was an addition of a beetle species (Coleoptera: Meloidae) (Pallas, 1782), which was collected from both sheep and pig carcasses but unique to the warm season. The pig carcass attracted more dipteran flies during both warm ( = 1,519) and cold season ( = 779) as compared to sheep carcass during the warm ( = 511) and cold season ( = 229). In contrast, coleopterans were more abundant on the sheep carcass during the warm season ( = 391) and cold season ( = 135) as compared to the pig carcass in both warm season ( = 261) and cold season ( = 114). In overall, more flies and beetles were collected on both sheep and pig carcasses during the warm season, and this further highlight that temperature influenced the observed difference in the abundance of collected arthropod between seasons.
当前的研究旨在对南非夸祖鲁 - 纳塔尔省寒冷和温暖季节猪和羊尸体上的节肢动物群落进行分子鉴定并比较其多样性。使用诱蝇器或镊子收集尸体上及周围发现的成年节肢动物。分子分析证实了在寒冷季节从羊和猪尸体上收集到的12种节肢动物的鉴定结果。结果表明，12种节肢动物中有11种在羊和猪尸体上都很常见，除了（鞘翅目：金龟科）（林奈，1767年）和（双翅目：蝇科）（龙达尼，1871年）物种，它们分别是羊和猪尸体特有的。然而，在温暖季节，与猪尸体相比，羊尸体吸引了更多的节肢动物（ = 13种）。所获得的节肢动物的差异是由于在此季节羊尸体上还存在 ，这也是羊尸体特有的。此外，还增加了一种甲虫物种（鞘翅目：芫菁科）（帕拉斯，1782年），它是从羊和猪尸体上都收集到的，但仅在温暖季节出现。与温暖季节（ = 511）和寒冷季节（ = 229）的羊尸体相比，猪尸体在温暖季节（ = 1,519）和寒冷季节（ = 779）吸引了更多的双翅目苍蝇。相比之下，与温暖季节（ = 261）和寒冷季节（ = 114）的猪尸体相比，鞘翅目昆虫在温暖季节（ = 391）和寒冷季节（ = 135）的羊尸体上更为丰富。总体而言，在温暖季节，在羊和猪尸体上收集到的苍蝇和甲虫更多，这进一步突出表明温度影响了不同季节收集到的节肢动物数量的差异。
