    Eotetranychus lewisi is an important pest in peach crops in various parts of the world and it has recently been reported in the province of Tungurahua, Ecuador. Therefore, in the present study, the biology and life table of E. lewisi were studied on three peach varieties (‘Zapallo’, Blanco abridor’and ‘Tejón’) under laboratory conditions (). The study was conducted in the Entomology laboratory of the Faculty of Agricultural Sciences, UTA. The mites were collected from Euphorbia pulcherrima. The effect of the variety on the duration of the life cycle of E. lewisi was demonstrated, observing that the lewis mite did not develop when reared on Zapallo leaves, while life cycle was similar in ‘Abridor’ and ‘Tejón’. Regarding the reproductive parameters, Tejon proved to be the breeding substrate that offers the greatest development potential for E. lewisi since it presented less pre-oviposition time and greater fertility, which was evidenced in the parameters of the table of life where it presented the highest data in the net reproduction rate (Ro). Based on the results, cultivar Zapallo seems to have resistance mechanisms to this pest, so its inclusion in a pest management program could be considered.
