AbstractWild bee pollinators were collected in tree-fruit orchards and uncultivated habitats in the Okanagan Valley. Higher abundance and diversity of wild bee pollinators were found at uncultivated sites than on tree-fruit crops. Wild bees were not abundant enough in orchard habitats to provide adequate tree-fruit pollination. Variable flower visitation patterns by polylectic bees in orchard and uncultivated habitats make it difficult to predict floral visitation patterns. Therefore, orchardists cannot rely on a substantial and predictable contribution to pollination of fruit crops by wild bee species. Research into the use of wild bees as managed pollinators for tree-fruit crops in the Okanagan Valley may have potential. Future studies should consider three wild bee species collected in Okanagan Valley orchards, Bombus terricola occidentalis Greene, Bombus bifarius nearcticus Handlirsch, and Osmia lignaria propinqua Cresson, for pollination management.

Foliar Urea

Reserve nitrogen is an important factor for plant growth and fruiting performance in tree fruit crops. The fall foliar urea application appears to be an efficient method for increasing N reserves. The effect of fall foliar urea application on N reserves and fruiting performance were studied with four year old `Gala'/M26 trees grown in 20 gallon containers in a pot-in-pot system from 2001 to 2003 at the Lewis-Brown Horticulture Farm of Oregon State Univ.. The trees were either sprayed with 0 or 2 times 3% urea after harvest in October. Shoot and spur samples were taken at the dormant season for reserve N analysis. Fruit performance was recorded in the following growing season. The fall foliar application significantly increased spur N reserve and had the trend to increase shoot N reserve but not significantly. The fall foliar application significantly increased tree fruit set and cluster fruit set. With normal fruit thinning, fall foliar urea application has the trend to increase both tree yield and average fruit size; without fruit thinning, fall foliar urea application has the trend to increase tree yield. These results indicate that fall foliar urea application an effective method to increase reserve N for maintaining tree yield.
