Biological control of two-spotted spider mite is interesting in everbearing strawberry culture, because its harvesting period stretching over more than four months makes it difficult to apply a classical acaricide treatment schedule. In strawberry cultures on substrate, three years of two-spotted spidermite control with the predator Phytoseiulus persimilis showed that a satisfactory control could be obtained under certain conditions. The auxiliary has to be ordered as soon as the leaves occupation rate by the pests reaches 10%.With a concentration of tenmobile predators per m2, it takes two weeks until the pest population decreases. After four weeks, the spider mites were controlled. In the event of a strong attack of mites, it is recommended to combine the auxiliaries release with an acaricide treatment with fatty acid. With such a biological pest control, the fruit quality is not reduced and the cost is affordable for the producer.
