Abstract: | Los murciélagos son frecuentemente parasitados por dípteros hematófagos de las familias Streblidae y Nycteribiidae, poco estudiados en Ecuador pese a su gran diversidad de quirópteros. Para abordar esta brecha, se realizó una revisión exhaustiva de la literatura sobre asociaciones ecuatorianas hospedero-parásito complementada con examinación en campo de 200 murciélagos de cuatro provincias. Se registraron datos para 21 especies de moscas de murciélagos asociadas a 17 especies de hospederos, incluyendo dos nuevos registros para Ecuador (Anastrebla caudiferae y Trichobius petersoni). Además, 14 combinaciones hospedero-parásito fueron nuevas para el país, la mitad de estas nuevas también para la literatura. Hallazgos notables incluyen los primeros ectoparásitos para Anoura aequatoris e interacciones entre Exastinion deceptivum y especies de Anoura distintas de A. peruana. Varias asociaciones mostraron alta especificidad, particularmente las del género Anastrebla, mientras que parásitos menos específicos incluyeron Exastinion deceptivum y especies asociadas a Carollia. Adicionalmente, se detectaron cinco asociaciones no primarias, tres de ellas probablemente ecológicas en origen. Análisis de prevalencia indican tasas de infestación altas en poblaciones de Sturnira bogotensis y Anoura peruana, y bajas en Artibeus lituratus y Glossophaga soricina de Manabí. Análisis preliminares a nivel de red apoyan alta especialización y modularidad, consistente con investigaciones previas sobre estos sistemas. En resumen, los hallazgos en este estudio contribuyen a la diversidad conocida de las moscas de los murciélagos ecuatorianas, apoyan alta especificidad de hospedero en el país y remarcan la importancia de futuras investigaciones en regiones poco exploradas, como los ecosistemas montanos que aportaron parte significativa de los nuevos registros. |
Description: | Bats are often parasitized by a variety of hematophagous dipterans from the families Streblidae and Nycteribiidae, understudied in Ecuador despite the large diversity of Chiroptera in the country. To address this gap, a comprehensive literature review on Ecuadorian host-parasite reports was combined with field examinations of 200 bats from four provinces. Original data was recorded for 21 species of bat flies associated to 17 host species, including two new parasite species for Ecuador (Anastrebla caudiferae and Trichobius petersoni). In addition, 14 host-parasite combinations were new for Ecuador, half of them also new for literature. Notably, the first ectoparasites for Anoura aequatoris, as well as interactions between Exastinion deceptivum and species of Anoura other than A. peruana. High host specificity was observed in many associations, particularly for bat flies of the genus Anastrebla, while less specific parasites included Exastinion deceptivum and Carollia-associated bat flies. Additionally, five non-primary associations were detected, three of which were likely ecological in nature. Values obtained from site-specific prevalence analysis indicate high infestation rates in populations of Sturnira bogotensis and Anoura peruana, and lower prevalence in Artibeus lituratus and Glossophaga soricina in Manabi. Preliminary network-level analysis support high specialization and modularity, consistent with previous research regarding bat-bat fly systems. In summary, the findings in this study contributed towards the known diversity of Ecuadorian bat flies, support high host-specificity in the country and highlight the importance of further exploration in understudied regions such as montane ecosystems, which provided a significant portion of the new records. |
