This paper studies the impacts of antemortem ingestion of alcoholic beverages by the domestic rabbit, L., on postmortem successional patterns of insects during winter and summer 2018 in Riyadh, Saudi Arabia. Insect samples were collected from the carcasses of rabbits fed alcoholic beverages as well as untreated rabbits for 15 days postmortem during two successional studies in each season. The results showed that, during both seasons, the decomposition process for the carcasses of rabbits fed alcoholic beverages antemortem was one to two days longer. The results also showed, however, that alcoholic beverages did not affect insect succession patterns in either season. In fact, the number of insects appeared to be influenced by the ambient temperature during the two seasons, with 4415 insects in the winter compared to 1033 insects in the summer. In total, 30 insect taxa were collected during the winter study from the carcasses of rabbits fed alcoholic beverages antemortem; while 26 of these same taxa were collected from the carcasses of the untreated rabbits. Among the treated rabbits, those fed 25 ml alcoholic beverages treated attracted the highest number of insect taxa (24 taxa). In the summer study, 21 insect taxa were collected in total, 19 from the carcasses of the alcohol-treated rabbits and 13 from untreated rabbits. Among the treated rabbits, those fed 50 ml alcoholic beverages attracted the highest number of insect taxa (14 taxa). These results contribute to the understanding of the factors affecting the use of insects in medical investigations, given that alcoholic beverages are a common addictive agent.
本文研究了家兔（穴兔）生前摄入酒精饮料对2018年冬夏两季沙特阿拉伯利雅得市昆虫死后演替模式的影响。在每个季节的两项演替研究中，从喂食酒精饮料的兔子尸体以及未处理的兔子尸体上采集昆虫样本，采集时间为死后15天。结果表明，在两个季节中，生前喂食酒精饮料的兔子尸体的分解过程都延长了一到两天。然而，结果还表明，酒精饮料在两个季节中均未影响昆虫的演替模式。事实上，昆虫数量似乎受两个季节的环境温度影响，冬季有4415只昆虫，而夏季有1033只昆虫。在冬季研究中，总共从生前喂食酒精饮料的兔子尸体上采集到30个昆虫类群；而从未处理兔子的尸体上采集到其中26个相同的类群。在经处理的兔子中，喂食25毫升酒精饮料的兔子吸引的昆虫类群数量最多（24个类群）。在夏季研究中，总共采集到21个昆虫类群，19个来自经酒精处理的兔子尸体，13个来自未处理的兔子尸体。在经处理的兔子中，喂食50毫升酒精饮料的兔子吸引的昆虫类群数量最多（14个类群）。鉴于酒精饮料是一种常见的成瘾剂，这些结果有助于理解影响在医学调查中利用昆虫的因素。
