- Cowpats containing Culicoides larvae were frozen at different temperatures.
- Emergence of Culicoides from frozen and non-frozen subsamples was compared.
- No individuals of C. dewulfi survived freezing.
- Some individuals of C. chiopterus survived freezing at â18 °C, but not at â21 °C.
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 48 h at â18 and â21 °C. Emergence from frozen and non-frozen samples was compared. The number of emerging adults of C. chiopterus from samples frozen at â18 °C was greatly reduced and no emergence was observed from samples frozen at â21 °C. No adult C. dewulfi emerged from frozen samples, suggesting this species is less resistant to these temperatures, compared to C. chiopterus.
