Efficacy of predatory mite, Amblyseius swirskii (Athias-Henriot) as a biological control agent of chilli thrips, Scirtothrips dorsalis Hood, was compared to a Capsicum oleoresin extract-based biopesticide, and a conventional insecticide, spinetoram, on entire strawberry (var. ‘Radiance’) plants with 5 expanded trifoliates under greenhouse conditions. Results indicate that A. swirskii and the biopesticide can be included as effective tools for integrated pest management of S. dorsalis in strawberries.



Se comparó la eficacia del ácaro depredador Amblyseius swirskii (Athias-Henriot) como agente de control biológico del trips del chile, Scirtothrips dorsalis Hood, con un biopesticida basado en extracto de oleorresina de capsicum y un insecticida convencional, spinetoram, sobre plantas entera de fresa (var. ‘Radiance’) con 5 trifoliatos expandidos bajo condiciones de invernadero. Los resultados indican que A. swirskii y el biopesticida pueden incluirse como herramientas efectivas para el manejo integrado de plagas de S. dorsalis en fresas.
