Sex Ratio and Abundance Fluctuations of Sarcosaprophagous Calyptratae (Diptera): Field Evaluation of Two Sampling Techniques

A study comparing two sampling techniques for sarcosaprophagous Calyptratae (Diptera) flies in Los Alerces National Park and other Valdivian temperate forests found that bottle traps baited with putrescine reliably estimate local abundance, matching active capture methods. The research also revealed significant intraspecific sex ratio differences between the two techniques, despite expected interspecific variations in trapping efficiency. This insight highlights the importance of selecting appropriate sampling methods to accurately assess fly populations and their sex ratios, which could impact ecological studies and conservation efforts.
