“…UC has conducted strawberry breeding continuously since 1930 (Bringhurst and Voth 1960), and the improvement of traits important for commercial productivity has been substantial (Shaw and Larson 2008). The choice of parents for the population-improvement component of this program has depended in part on resistance to important pathogens, and the longest continuous screening effort has been dedicated to Verticillium dahliae Kleb.…”

“…The response to selection for horticultural traits has been well documented in the UC program. For example, Shaw and Larson (2008) demonstrated improvement of 47% to 140% for yield, fruit size, fruit appearance Cross year Verticillium resistance score genotypes may or may not exist within the currently available germplasm, but there is no reason to suspect its absence until more sensitive tests are developed.…”

Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is a major pest of strawberry. The efficacy of three species of predatory mites, Typhlodromips montdorensis (Schicha), Neoseiulus cucumeris (Oudemans) (both: Acari: Phytoseiidae), and Hypoaspis miles (Berlese) (Acari: Laelapidae), and their compatibility with spinosad for the control of this thrips was evaluated in commercial strawberry in spring. Low tunnel‐grown strawberry was treated with ‘water then mites’, ‘spinosad then mites’, or ‘mites then spinosad’. Predatory mites were released as single‐, two‐ and three‐species combinations. Overall, spinosad‐treated plants had fewer thrips than water‐treated plants (control). In all treatment regimes, each species of predatory mite reduced the number of thrips relative to those plants that received no mites. Predatory mites were most effective in reducing thrips when released after spinosad was applied. Any multiple‐species combination of predatory mites reduced thrips numbers more than single‐species releases. The two‐species combination of T. montdorensis (foliage inhabiting) and H. miles (soil dwelling) was the most effective in suppressing thrips. The next most effective combination was a three‐species release. Of multiple‐species combinations, the two‐species combination of T. montdorensis and N. cucumeris was the least effective in suppressing thrips numbers. The spinosad and mites only temporarily reduced the numbers of F. occidentalis. This suggests that further application of predatory mites, spinosad, or both is required to maintain F. occidentalis populations below an economically damaging level.

“…Runners of strawberry, Fragaria x ananassa Duchesne (Rosaceae) cultivar Camino Real (short day), developed by the University of California,40, 41 were planted in potting mix (Baileys Fertilisers, Rockingham, WA) in 325 mm × 325 mm × 405 mm plastic pots and kept in glasshouses at UWA and the Department of Agriculture and Food Western Australia (DAFWA), South Perth, WA. All pots were fitted with drippers with an automatic timer and watered every third day.…”
