First report of Eotetranychus lewisi in the Andean region from Ecuador on Arracacia xanthorrhiza (white carrot), Tropaeolum tuberosum (mashua)

Abstract:

Eotetranychus lewisi (McGregor) is reported for the first time on white carrot (Arracacia xanthorrhiza Bancr.) and mashua (Tropaeolum tuberosum Ruiz y Pavon) in Province of Tungurahua, Ecuador. Highest population levels of E. lewisi were observed on a purple petiolated and vein A. xanthorrhiza while on mashua only a lower number of this mite was registered. Observations were made at Facultad de Ciencias Agropecuarias, Universidad Técnica de Ambato. Based on economic importance of white carrot in rural communities it is suggested to carry out more detailed studies dealing potential impact of E. lewisi in the Ecuadorian Sierra.
