Feltiella acarisuga (Vallot, 1827) (Diptera: Cecidomyiidae) is an effective and common beneficial species that feeds on many species of Tetranychid mites. Although it has been detected in Turkey, there are few studies on this predatory species. In this study, weekly leaf samples were taken to represent the growing area in the soilless strawberry greenhouse of Akdeniz University in 2020 and 2021. In leaf examinations, it was determined that F. acarisuga had an average egg size of 0.21 mm, young and mature larva of 0.26-1.51 mm, and a cocoon size of 2.01 mm. The average body length of male and female individuals was measured as 0.89 mm and 1.11 mm, respectively. It was determined that F. acarisuga can feed on all biological stages of Tetranychus urticae Koch, 1836 (Acari: Tetranychidae), as eggs, larvae, nymphs and adults were seen in the greenhouse in all seasons. Feltiella acarisuga is the most common natural enemy of T. urticae, with a maximum average of 0.38 larvae + cocoons/leaf in the greenhouse in the first year and 0.62 larvae + cocoons/leaf in the second year. In this study, a new species was detected, Aphanogmus sp., which was determined to be the parasitoid of F. acarisuga and different from its known congeners. The parasitization rate of F. acarisuga was found to be between 0 and 51.5%.

Feltiella acarisuga (Vallot, 1827) (Diptera: Cecidomyiidae), Tetranychid akarların birçok türü ile beslenen etkili ve yaygın bir doğal düşman türüdür. Türkiye’de varlığı tespit edilmiş olmakla birlikte bu predatör tür ile ilgili olarak son derece kısıtlı çalışmalar bulunmaktadır. Bu çalışmada 2020 ve 2021 yıllarında, Akdeniz Üniversitesine ait topraksız çilek serasında üretim alanını temsilen haftalık yaprak örnekleri alınmıştır. Yaprak incelemelerinde, F. acarisuga'nın ortalama 0,21 mm yumurta, 0,26-1,51 mm genç ve olgun larva, 2,01 mm kokon büyüklüğüne sahip olduğu belirlenmiştir. Erkek ve dişi bireylerin vücut uzunluğu ise sırasıyla ortalama 0,89 mm ve 1,11 mm olarak ölçülmüştür. Feltiella acarisuga’nın, Tetranychus urticae Koch, 1836 (Acari: Tetranychidae)’nin yumurta, larva, nimf ve ergin olmak üzere tüm biyolojik evrelerinde beslenebildiği ve tüm sezon boyunca serada görülebildiği tespit edilmiştir. En yoğun olarak, ilk yıl serada ortalama 0.38 adet larva + kokon/yaprak, ikinci yıl ise 0,62 adet larva + kokon/yaprak tespit edilmiş olan F. acarisuga'nın, T. urticae’nin en yaygın doğal düşmanı olduğu belirlenmiştir. Feltiella acarisuga'nın parazitoiti olarak belirlenen ve bilinen türdeşlerinden farklı yeni bir tür olan Aphanogmus sp'nin tespit edildiği bu çalışmada, F. acarisuga’nın parazitlenme oranı %0-51,5 arasında bulunmuştur.
