Abstract
Strawberry Fragaria x unanussa Duchesne is attacked by many arthropod pests, both insects and mites, in addition to pathogens, which vary widely in their distributions and host damage.Tetranychid mites are the most attacking group found on strawberry both in greenhouses and fields. Borage Borngo officinnlis L. has been found to be a companion plant of strawberry as it attracts honeybees and other pollinators. Moreover, Predatory mites of the family Phytoseiidae as well as some insects are considered to be among the most important natural enemies of spider mites on strawberry and several other cultivated plant species. Plant -based foods i.g. pollen may serve as alternative resources in meeting the nutritional requirements of predatory mites and insect predators. Therefore, the present study was carried out to investigate acceptance of 16 tetranychid mite species on both borage and strawberry as host plants as well as studying host plant suitability of the same tetranychid mite species on borage and three strawberry cultivars, being; Nyoho, Sagahonoka, and Toyonoka. On the other hand, the effect of borage on phytoseiid predatory mites and insect predators that utilize to control spider mites in strawberry greenhouses through preference, reaching time and prey egg consumption. In addition to the use of pollen grains of two plants as an alternative food for predators maintainence when the preferred prey species is scarce.
