The first record of Zygothrica orbitalis (Sturtevant, 1916) for the state of Rio Grande do Sul and the southernmost limits for seven species of Drosophilidae (Insecta: Diptera) (original) (raw)

AI-generated Abstract

This study reports the first occurrence of Zygothrica orbitalis in the state of Rio Grande do Sul, Brazil, and establishes the southernmost distribution limits for seven species of Drosophilidae within the Pampa Biome. Utilizing McPhail traps baited with Karo® syrup, a total of 78 drosophilids were collected, revealing a shift in species abundance compared to traditional bait methods, notably surpassing D. simulans in favor of L. cf. maculosa. The findings underscore the importance of diversified sampling methods for accurately assessing Drosophilidae diversity.
