Emerging Invasive Pest Mites and Mite-Transmitted Diseases

Spider mites (Acari: Tetranychidae) distribution in high-Andean peatlands of the Salinas and Aguada Blanca National Reserve of Arequipa, Peru

Sunday, November 5, 2023
4:00 PM – 4:15 PM ET
Location: Gaylord National Resort & Convention Center, Chesapeake 6
In-Person
The first phytophagous mite surveys were carried out in the Salinas and Aguada Blanca National Reserve of Arequipa in October-December 2021 and March-September 2022. A total of 330 samples of Distichia muscoides peats were collected from the wetlands areas of the eight localities of the National Reserve. Over 2503 specimens of spider mites were collected using Berlese-Tullgren funnels. Mites were preserved using Hoyer´s medium, dried on a slide warmer and identified under a Phase Contrast Microscope. Two species were found, Beerella sp (Bryobinae) represented by 53.9% (1350/2503) in five localities and Tetranychus sp (Tetranychinae) with 46.1% (1153/2503) in all eight localities. The occurrence of spider mites associated with wetlands is presented for the first time for Peru and notes about distribution and ecology are discussed.
