The detection and frequency of two ectoparasitic mite species (Acari: Trombidiformes: Stigmaeidae & Microtrombidiidae) on field collected sand flies (Diptera: Phlebotomine) in Western Türkiye

Mites are known to attach to and parasitize sand flies, potentially affecting host survival, development and reproductive capacity. In this study, we aimed to identify and report two mite species found on the field collected sandflies during a comprehensive seasonal activity study carried out in two provinces of T & uuml;rkiye. A total of 4 3 mite specimens were recovered from 25 individual sand flies. Two mite species Eustigmaeus johnstoni Zhang & Gerson (Stigmaeidae) and Biskratrombium aff. coineaui Fain & Izri (Microtrombidiidae) were identified . This represents the first record on the presence of ectoparasitic B. aff. coineaui on adult females of Phlebotomus alexandri and P. sergenti, and the first to report of this mite species from T & uuml;rkiye. Although the effects of parasitic mites on sand fly populations remain unclear, it is likely that they utilize the host's limited resources, thereby potentially compromising the host's reproductive potential. Further experimental investigation into these specific host-parasite dynamics is essential to fully elucidate the ecological interactions and their potential implications for vector management.
