 OB:  To develop strawberry cultivars that have desirable horticultural
 characteristics and resistance to diseases and arthropod pests that are
 important in Florida. 
 AP:  Strawberry varieties and breeding stocks from various parts of the world
 which are known to possess horticultural characteristics or pest resistance
 desirable in Florida varieties will be obtained and tested to determine if
 these characteristics are exhibited under local growing conditions. Controlled
 crosses will be made between selected clones and selection from seedling
 populations will be performed. Selections will be based on yield,
 horticultural and fruit characteristics, fruit quality, and resistance to
 diseases, arthropods and nematodes.

      Research involving twospotted spider mites (Tetranychus urticae) as pests
 of strawberries showed that: 1) Four weekly applications of cyhexatin reduced
 mites on fruiting strawberries, but not as well as did twice weekly
 applications. Mites remained low for 2 weeks; 2) Methomyl treatments reduced
 natural mite predators and increased mite densities; 3) Cyhexatin,
 clofentezine and hexythiazox miticides applied in various programs reduced
 mite densities; 4) Little differences exist among 20 strawberry cultivars or
 breeding lines in their capacity to support spider mite population increase;
 5) Strawberry cultivars and breeding lines vary in their amount of
 deterioration due to spider mites feeding; 6) Strawberry cultivars and lines
 that produce larger amounts of foliage during the period of mite population
 development tended to survive spider mite infestations better than other
 plants; 7) No important advantages were detected between success of
 Phytoseiulus persimilis and P. macropilis as biological control agents; 8)
 When P. persimilis was applied at the density of one per plant, there was no
 advantage to applying one per plant again 1 and 2 weeks later; 9) P.
 persimilis predators were found 23 meters from release points 1 week after
 release; 10) Deutonymphal P. persimilis are dispersed by wind from densely
 colonized host plants.
