The emergence of Culicoides chiopterus (Meigen), 1830 and C. dewulfi Goetghebuer, 1936 (Diptera: Ceratopogonidae) from cowpats in northwestern Germany was investigated. In order to investigate the survival of both species at low temperatures, cowpat subsamples were frozen for 48h at -18 and -21°C. Emergence from frozen and non-frozen samples was compared. The number of emerging adults of C. chiopterus from samples frozen at -18°C was greatly reduced and no emergence was observed from samples frozen at -21°C. No adult C. dewulfi emerged from frozen samples, suggesting this species is less resistant to these temperatures, compared to C. chiopterus.
对1830年的库蠓（Culicoides chiopterus (Meigen)）和1936年的德氏库蠓（C. dewulfi Goetghebuer）（双翅目：蠓科）在德国西北部牛粪中的羽化情况进行了调查。为了研究这两个物种在低温下的存活情况，将牛粪子样本在-18°C和-21°C下冷冻48小时。比较了冷冻样本和未冷冻样本的羽化情况。在-18°C冷冻的样本中，库蠓羽化的成虫数量大幅减少，而在-21°C冷冻的样本中未观察到羽化现象。冷冻样本中没有德氏库蠓成虫羽化，这表明与库蠓相比，该物种对这些温度的耐受性较差。
