Resumen:
Wild vegetation surrounding crops may provide temporary habitat andpotential food sources for phytoseiids in different seasons. Monthly vegetation samples of wild plants adjacent to strawberry plants and wild plants in a vegetation strip close to thecrop were taken. The frequency of Neoseiulus californicus, Tetranychus urticae and othermites and insects was recorded. In addition, in a laboratory assay, the survival, developmentaltime and fecundity of females fed on pollen of strawberry and pollen of wild plantswhere N. californicus was recorded during their flowering, were estimated. Pollen fromUrtica urens, Lamium amplexicaule, Convolvulus arvensis, Sonchus oleraceous, Galegaofficinalis, and Fragaria x ananassa (strawberry) allowed development of N. californicusto adult, but not reproduction. Survival was 70?80 % when fed on pollen from S. oleraceus,G. officinalis and C. arvensis, 80?90 % when fed on pollen from U. urens and F. xananassa, and more than 90 % when fed on T. urticae and on pollen from L. amplexicaule.In autumn and winter, U. urens, L. amplexicaule and S. oleraceous could promote thepersistence of N. californicus when prey density in strawberry is low, offering T. urticae,thrips and pollen. In summer, pollen of C. arvensis and G. officinalis would contribute tothe persistence of N. californicus when the strawberry crop is ending and offers scarce foodresources. Although the pollen of these plants would not enable the predator population toincrease, the presence of these plants in the vicinity of strawberry could contribute to thepersistence of N. californicus population and help to limit T. urticae growth when this pestbegins to colonize the crop.
